Subject: image size depends on screen resolution
Message-ID: <NDBBKMPGELCFDJPOHAMEOEPKCAAA.peter42@dds.nl>

Hello,

I've implemented a very small Java script for creating a mapserv image where
the size depends on the resolution of the screen of the user. I thought that
perhaps some of you might be interested. Just put something like this in the
HTML template

<script language=Javascript>
        <!--
            if (screen.width==800)
            {
                var imgsizex=420;
                var imgsizey=320;
            }
            if (screen.width>800)
            {
                var imgsizex=600;
                var imgsizey=480;
            }
            document.write ('<input type="hidden" name="mapsize"
value="'+imgsizex+' '+imgsizey+'">');
         //-->
</script>

Now you've created just another hidden input type that is being send to the
mapserv

Regards,

Peter

Hello Stephen and others,

It works for all the browsers I've tested. These are Microsoft Internet
Explorer and Netscape for both Linux as Windows.
It's in my opinion a very common Java code.

The book in front of me here says the screen javascript object is available in 
Navigator 4 and Internet Explorer 4 (and presumably 5).  It is not available in 
earlier versions.

Message-ID: <s8bea1e6.098@gwgate.dnr.state.mn.us>

There is a EMPTY parameter for the webObj. The argument is a fully qualified URL
to redirect users to when a query returns an empty result set. For example:

  EMPTY "http://myserver.com/mapapp/notfound.html" 

Similarly there is an ERROR parameter for other error messages. If EMPTY is not
defined than all errors are redirected to ERROR. If neither is defined then the
standard error message is used.

the MapServer falls back on a bounding box intersection test FOR EACH

Subject: mapserv & PHP
Message-ID: <NDBBKMPGELCFDJPOHAMEAEAJCBAA.peter42@dds.nl>

Hello,

A year ago there were some meesages about the combination of mapserv and
PHP. Stephen explained that it is immpossible to combine them because the
results of mapserv are sent directly to the user instead of Apache.
I use PHP in the template files and make the template files update the
shapefiles (using mascript). This works OK.
I have 1 other remark. I'm testing a WAP way for the mapserv that will be
able to fetch all the information to local mobile phones (I think the
Wireless Application Protocol=WAP is European, but I'm not sure)
If anyone is interested, please mail me

Regards,

Peter

Howdy,

I'm afraid this is going to be a typical newbie-type question but...

I've downloaded the complete mapserv package and installed it according to
the instructions on the web site.  I am now testing the mapscript with
some sample data I grabbed from ESRI's web site. 

Unfortunately, when I run my test script, I get the following error:

Can't load
'/usr/lib/perl5/site_perl/5.005/i386-linux/auto/mapscript/mapscript.so'
for module
mapscript: /usr/lib/perl5/site_perl/5.005/i386-linux/auto/mapscript/mapscript.so: undefined
symbol: gdImageGif at /usr/lib/perl5/5.00503/i386-linux/DynaLoader.pm line
169.

I'm compiling this under Redhat Linux 6.1 (kernel 2.2.12-20) with perl
5.005.  I believe I've got everything installed right although it looks
like mapscript doesn't know where to find the gdImageGif Function.

Suggestions?

I am not that familiar with mapscript (and perl) but what version of
the gd-library is installed on your system ? The developers dropped
gif-support from the library due to the licence issues with Unisys 
(they hold a patent on the LZW data compression used by the gif format).
Newer versions of gd (>= 1.6 ?) support only png-format (which is not a
limitation IMO). MapServer is alrady reflecting this by a define-rule
to be set in the makefile (GD=-DUSE_GD_1_6).

Cheers,

        Frank

I'm using the version of gd-lib that comes with mapserv (gd-1.2) which
looks like it still supports GIF.  I've tried recompiling everything
(including mapscript) and re-installing to no avail.

If there is any additional information you need, please let me know.

This is how I initially installed it.

At someone's suggestion (Thanks Steve!  It's appreciated!), I've also
copied libgd.a to /usr/lib but that didn't work either... :(

Subject: Building 3.3.007
Message-ID: <s8c3adec.080@gulf-states.com>

I recently downloaded and built ms_3.3.007 with no problems.  I built it with gd-1.7.3 and libTiff.  I then copied the mapserv executable to my CGI directory.  Everything works fine.  I have 3 different projects set up and all work great.  Unfortunately, I removed the ms_3.3.007 directory before copying the other utilities.  So, I was just going to replicate what I did before and copy the utilities and the mapscript stuff.  However, when I try to build it now, I get the errors shown below.  I thought that I did everything identical to before, but apparently not.  Here's what I did:

1) tar xzvf ms_3.3.007.tar.gz
2) cd ms_3.3.007
3) tar xzvf ../gd-1.7.3.tar.gz
4) vi Makefile (changed all references to gd-1.2 to gd-1.7.3 and all -DUSE_GD_1_2 to -DUSE_GD_1_6)
5) cd gdft
6) vi Makefile (changed all references to gd-1.2 to gd-1.7.3 and all -DUSE_GD_1_2 to -DUSE_GD_1_6)
7) cd ..
8) make
9) Got "maplabel.c:13: freetype.h: No such file or directory"
10) make clean
11) cd gdft
12) cp /usr/local/include/freetype/*.h .
13) cd ..
14) make

then, I get the following.  Any ideas?  Since my mapserver is working OK, should I just wait for ms_3.3.008?

Thanks,

Robert Aldridge

I've seen this error before. Did you add the -lpng -lz to the library defines in the Makefile's?

>>> "Robert Aldridge" <RALDRIDG at gulf-states.com> 03/06/00 01:08PM >>>
I recently downloaded and built ms_3.3.007 with no problems.  I built it with gd-1.7.3 and libTiff.  I then copied the mapserv executable to my CGI directory.  Everything works fine.  I have 3 different projects set up and all work great.  Unfortunately, I removed the ms_3.3.007 directory before copying the other utilities.  So, I was just going to replicate what I did before and copy the utilities and the mapscript stuff.  However, when I try to build it now, I get the errors shown below.  I thought that I did everything identical to before, but apparently not.  Here's what I did:

1) tar xzvf ms_3.3.007.tar.gz
2) cd ms_3.3.007
3) tar xzvf ../gd-1.7.3.tar.gz
4) vi Makefile (changed all references to gd-1.2 to gd-1.7.3 and all -DUSE_GD_1_2 to -DUSE_GD_1_6)
5) cd gdft
6) vi Makefile (changed all references to gd-1.2 to gd-1.7.3 and all -DUSE_GD_1_2 to -DUSE_GD_1_6)
7) cd ..
8) make
9) Got "maplabel.c:13: freetype.h: No such file or directory"
10) make clean
11) cd gdft
12) cp /usr/local/include/freetype/*.h .
13) cd ..
14) make

then, I get the following.  Any ideas?  Since my mapserver is working OK, should I just wait for ms_3.3.008?

Thanks,

As a followup to the undefined symbol problem, I've noticed when the
installation script for mapscript runs Mkbootstrap, it creates a file
called mapscript.bs.

This file is a zero-length file.

Could this have anything to do with it?

Just for fun, I tried compiling mapserver/mapscript with gd-1.7.3 instead
of gd-1.2.  Upon re-installation, it told me that png_get_error_ptr was
undefined.

I then decided to go into the gd-1.7.3 src and make sure the thing was
installed.  In the course of fiddling with it, I discovered that libgd.a
was being installed in /usr/local/*

Normally, this wouldn't be a problem except that in my work environment
/usr/local is actually NFS-mounted off of another machine.  Furthermore,
there is already another version of libgd.a in there.

So my guess is that mapscript is trying to link off of that other version
of libgd.a which is causing the problems (I've no idea what version is on
the NFS server).

So basically, I've got two options:

1) Install the latest-n-greatest version of GD on the NFS box
   (risky.  Could break other programs)

2) Install mapserver on a completely separate machine.

Thanks for the help!

Chris,

I'd recommending building the libraries locally, and link GD (possibly
others) statically.   The dynamic libraries could be a problem, especially if
they are NFS mountes.  Sounds like a questionable practice to me.


With 3.3.007 make sure that the mapscript "Makefile.PL" uses the 
same -D defines as the mapserv Makefile.  That one, I had to tweak
by hand.

That is about the only other suggestions I can make.

-Chris

This is strange though. I just installed all this on an Alpha running RH6.1 with no problem. There was another version of GD installed on that box as well. Anyone know if -L./gd takes precedence over anything found in default library locations (i.e. /usr/lib or /usr/local/lib) or the other way around?

Normally the system compiler (assuming gcc) will search predefined paths
(/usr/lib) before searching user-specified paths unless you specify the
compiler option '-nostdlib' before the '-L', in which it will search only
the specified paths.

That's what layer TYPE POLYLINE is for. You can use any line symbol

Hi all,

does anyone know if it is poosible to render 24-bit TIF files instead of the
8-bit raster files?
Is it perhaps possible with the jpeg library?
People then have the possibility to choose between a very sharp but slow
picture or a less sharp but faster picture.

I think the jpeg support is currently limited to input only, but it would
be great to render 24-bit TIFFs.  By the time you whack a 24-bit image
to 8-bits...  It doesnt look so great anymore.

Adobe Illustrator has the ablility to zoom into a 24-bit TIFF 
without pixelization or distortion of any kind.  The output is
really nice.... I was hoping to see a similar functionality
is some other free graphic package like ImageMagick or GIMP.  

Is it libtiff's limitation to do < 8-bit images, or what?  
PNG is a output option, but JPEG would be nice too.    While on the topic
of wants...  Does anyone know of a public b-spline routine for multipoint
labelling?  Or perhaps another algorithm that might work?

Regards,

-Chris

The limitation is not due to libtiff. It can handle just about any friggin tiff you give it. The limitation is purely one of GD. It can only produce 8-bit output. It's a big move to 24-bit graphics so I'm not surprised they have't done it yet although it is in the works. MapServer is poised to take advantage of it when it does happen (notice all the colors are rgb etc.).

There are some practical reasons why not to use 24-bit output. Number one is there really isn't a decent format yet. Yes, png is promising but many browsers don't support it. File sizes are another.
MapServer 8-bit output compresses well. Triple the file size (at least) and users won't be that happy. Lastly there are performance issues. Antialiased graphics, update 3+ image planes all takes time. Imagemagick supports some of the GD functionality in 24-bits but is 6 to 8 times slower. A high price to pay. JPEG simply is not well suited to line art applications.

BTW JPEG support is limited to 8-bit greyscale input. JPEG was not built to support random (ie. windowed) access so should be avoided at all cost. Use TIFF instead.

Your usage looks fine. It's the code that sucks. It appears that a few small bugs have rendered on-the-fly projection useless. I'm surprised nobody noticed since I think it's been busted for several versions. Anyway, it's fixed in 3.3.008 which I will release later today.

Just in it's begining. The basic hooks are there just need to write the guts. I finally have access to the SDE libs and a server so will be actively pursuing.

Hello List,

Just out of curiosity, what's the status of adding hooks to SDE data sources in Mapserver?

For those of you considering using the latest version
of GD, maybe you will have better luck with it than
I did. Even after changing all the Makefiles to reflect
the newer version of GD, it still wouldn't work.
I was getting an error that it couldn't find jinclude.h
I did some searching to find out what jinclude.h could
be, and my best guess is that it has to do with jpegs.
I made sure I had the latest jpeg and libjpeg libraries,
but it didn't help.

GD-1.8 requires a few more libraries, but making sure
I had the latest of each didn't help.

I finally switched it back to GD-1.2 and had no problems.

If any of you are going to use a version of GD other than
1.2 note that there are 2 places further down in the 
ms_3.3.008/Makefile where "GD-1.2" is hardcoded in.
So change the version there as well as in the top part.

The latest version of GD I had tried was 1.7.3. The jpeg stuff
is brand new. MapServer won't use it anyway cause at the
moment there is no way to toggle between PNG, JPG or BMP
output with the new version. I imagine you could compile
GD without JPEG support and it would probably work. I'll
try it at home.

Note: You don't have to edit any additional references in 
the Makefile to gd-1.2. Those references are to build and
clean up the 1.2 directory. If you want comment out the
line "MAKE_GD" to prevent it from being built. Otherwise
those other lines are harmless. In other words, only edit
lines in the GD section in the Makefile and the gdft/Makefile.

I used gd 1.7.3 (I think... I'm away from that computer right now...) and
had to move a couple of .h files around but everything else made and worked
fine.  Don't know about 1.8, however.

I have compiled mapserver 3.3-008 with GD 1.8 successfully.
Steve, you are right, GD has to be compiled without jpeg support.
Here the steps:

o in the Makefile of gd sources:
        - CFLAGS=-O -DHAVE_XPM -DHAVE_LIBTTF
        - LIBS=-lm -lgd -lpng -lz -lttf -lXpm -lX11
        - VERSION=1.8 # :)

o make libgd.a  

o in the Makefile of mapserver:
        - As described in the GD Section, add -lpng and -lz to
          GD_LIB for png-support and set GD=-DUSE_GD_1_6 
        - modify the path to libgd
        - #MAKE_GD=gd
                (to suppress compilation of gd-1.2 packed with the
                 mapserver)

o make

Thats it and it works fine for me (Since all other libs are available).

Regards,

        Frank

Greetings,

I'm using mapscript to draw building polygons on a basemap; users can
select building names/types from an interface - mapscript pulls the
appropriate polygon data from a Postgres database, creates a shapefile
and adds and draws the polygon as a layer to the overall map.

What I'd like to do is create a client side image map out of these
building polygons.  Obviously, the polygon geo-coordinates are easy to
access, but is there some way to access the corresponding image
coordinates that get created when the polygon layer is rendered by
mapscript/mapserver?  There's probably an easy way to calculate what the
corresponding image coordinates would be, but I'm just not seeing it.
Any ideas?

Thanks,

The easiest way would be to add a method to a shapeObj to apply a 
map to it. That is to clip, thin and transform the coordinates. It's a
pretty easy addition. However, I've frozen development until I get the
webCVS running with the folks at the UMN. It'll be a couple of weeks
before I can make the changes.

In order to build MapServer on NT, you will need makefiles and also the
regex package which is not standard in MSVC++.

The following ZIP file contains the regex source and the makefiles ready
to build MapServer on NT using MSVC++ 6.0:

    http://www2.dmsolutions.on.ca/mapserver/ms_vc_makefiles.zip

Extract the ZIP file on top of your ms_3.3.008 directory and follow the
instructions in the README.VC file to compile.

These makefiles compile only the basic MapServer without any optional
component (i.e. no TIFF, no PROJ.4, no FreeType, etc.).  I am planning
to start building MapServer with all these optional components as well
and will make my other makefiles available when I have them, likely
sometimes next week.

Also, for those looking only for executables, a version of the 3.3.008
exectuables can also be downloaded from:

    http://www2.dmsolutions.on.ca/mapserver/ms_3.3.008_win32.zip

Once again, these do not include any of the optional components... but I
should have a new version with at least TIFF and FreeType soon.

To those who wish to compile MapServer 3.3.008 and GD-1.8 with JPEG
support, here are the steps I used.

I'm assuming you have the supporting library sources under the
ms_3.3.008 directory tree and that you already have libpng and zlib. 
I'm also assuming your JPEG directory is called "jpeg6b" and your gd-1.8
directory is "gd-1.8".


1. Compile JPEG
 $ ./configure
 $ make
 $ make install

2. Edit GD-1.8 Makefile
  -  Add the JPEG source path to INCLUDEDIRS:

INCLUDEDIRS=-I../gd-1.8 -I../jpeg-6b -I/usr/include -I/usr/local/include
-I/usr/include/X11 -I/usr/X11R6/include/X11

3. Edit ms_3.3.008 Makefile
  - Change all gd paths to gd-1.8
  - Change GD=-DUSE_GD_1_2 to GD=-DUSE_GD_1_6
  - Add "-lpng -lz" to GD_LIB=-L./gd-1.8 -lgd

Here's a Makefile snippet:
***
GDFONT_OBJ=gd-1.8/gdfontt.o gd-1.8/gdfonts.o gd-1.8/gdfontmb.o
gd-1.8/gdfontl.o gd-1.8/gdfontg.o
GD_INC=-I./gd-1.8
GD_LIB=-L./gd-1.8 -lgd -lpng -lz
GD=-DUSE_GD_1_6
MAKE_GD=gd 
.
.
.
gd::
	cd gd-1.8; make; cd ..
***

4. Edit gdft Makefile to make use of gd-1.8 stuff

Here's a snippet of gdft Makefile
***
GD_INC=-I../gd-1.8
GD_LIB=-L../gd-1.8 -lgd -lpng -lz
GD=-DUSE_GD_1_6  
***

5. Compile MapServer



The key step is in configuring the JPEG source.  When you run
"./configure", it copies jinclude.h from one of the architecture
dependent jinclude files (i.e., jinclude.linux, jinclude.sgi).  Gd-1.8
looks for this file during compile.

Hope this helps.

To those who wish to compile MapServer 3.3.008 and GD-1.8 with JPEG
support, here are the steps I used.

I'm assuming you have the supporting library sources under the
ms_3.3.008 directory tree and that you already have libpng and zlib. 
I'm also assuming your JPEG directory is called "jpeg6b" and your gd-1.8
directory is "gd-1.8".


1. Compile JPEG
 $ ./configure
 $ make
 $ make install

2. Edit GD-1.8 Makefile
  -  Add the JPEG source path to INCLUDEDIRS:

INCLUDEDIRS=-I../gd-1.8 -I../jpeg-6b -I/usr/include -I/usr/local/include
-I/usr/include/X11 -I/usr/X11R6/include/X11

3. Edit ms_3.3.008 Makefile
  - Change all gd paths to gd-1.8
  - Change GD=-DUSE_GD_1_2 to GD=-DUSE_GD_1_6
  - Add "-lpng -lz" to GD_LIB=-L./gd-1.8 -lgd

Here's a Makefile snippet:
***
GDFONT_OBJ=gd-1.8/gdfontt.o gd-1.8/gdfonts.o gd-1.8/gdfontmb.o
gd-1.8/gdfontl.o gd-1.8/gdfontg.o
GD_INC=-I./gd-1.8
GD_LIB=-L./gd-1.8 -lgd -lpng -lz
GD=-DUSE_GD_1_6
MAKE_GD=gd 
.
.
.
gd::
        cd gd-1.8; make; cd ..
***

4. Edit gdft Makefile to make use of gd-1.8 stuff

Here's a snippet of gdft Makefile
***
GD_INC=-I../gd-1.8
GD_LIB=-L../gd-1.8 -lgd -lpng -lz
GD=-DUSE_GD_1_6  
***

5. Compile MapServer



The key step is in configuring the JPEG source.  When you run
"./configure", it copies jinclude.h from one of the architecture
dependent jinclude files (i.e., jinclude.linux, jinclude.sgi).  Gd-1.8
looks for this file during compile.

Hope this helps.

Hello everyone,

I was just wondering what would be the simplest way to convert some of my

Any command line utilities out there?

Thanks, Vinod

I'm working on street labeling (Auto Position, Auto Angle, etc.) and ran
into a weird TrueType labeling issue.

When I switch from bitmap to TrueType in 3.3.008 it looks like the label
overlay is rotated 90 degrees and mirrored.

Any thoughts?

This is a GD version mismatch problem. GD 1.3 and higher use a row major (i.e. pixel[y][x]) scheme for storing the images. There is code to handle this if the appropriate preprocessor variables are set. Did you edit Makefiles in both ms_3.3.008 and ms_3.3.00/gdft? Could also be extraneous versions of GD installed on your machine.

Hi everyone,

I am a newbie to the world of MapServer.

My system is:
NT 4.0 using IIS.
MapServer 3.3006

In my html code, I have a java applet that set the variable
imgxy(mouseclick), imgbox(the area of zoom in pixel) and submit the map
request.
The applet also set the zoom variable( 3-zoom in| 0-query/pan| -3-for zoom
out ).
The result of the zoom sometimes works and sometimes I get this error
message:

"loadForm(): Web application error. Reference map coordinate out of range."

Does anyone know what this message means?


Furthermore, There seems to be 3 ways to perform zooming:

1) zoomdir/zoomsize
2) zoom ( x > 0 - zoom in | 0 > x - zoom out | x = 0 - pan/query )
3) imgbox( x1 y1 x2 y2 )

a) Are there more than these three methods?
b) If these three methods were being used in the same HTML,
   which of these have more priority over the other?

Thanks in advance for your help.

Cheers!

Thanks Steve.

I've put together a quick and dirty little Perl routine that does the
job
too, for what it's worth.  Seems to work well so far.

I'm getting the coordinates for the shapes I want to render from a
Postgres
database -- these coordinates are retrieved in another routine and
stored
in @polygon in the form (point1x, point1y, point2x, point2y, point3x,
point3y ...),

Rob

sub create_imagemap {

    #Read image width and height from map file
    $imgwidth = $map->{width};
    $imgheight = $map->{height};

    #@polygon is a simple list that stores the real world coordinates of

the object pulled from the database
    @vertices = @polygon;

    #loop through the list grabbing each x and y coordinate and
converting
the geo-coordinate to image coordinates
    while (@vertices) {

         #grab first coordinate, remove any parentheses
        $xvert = shift(@vertices);
        $xvert =~ s/[\(\)]//g;

         #convert x map coordinate to image coordinates
        $cellsizex = (($map->{extent}->{maxx} -
$map->{extent}->{minx})/($imgwidth - 1));
        $ximg = (($xvert - $map->{extent}->{minx})/$cellsizex);

        #add image coord. to the new list
        push (@imgshape,$ximg);

        #grab second coordinate, remove any parentheses
        $yvert = shift(@vertices);
       $yvert =~ s/[\(\)]//g;

        #convert y map coordinate to image coordinates
        $cellsizey = (($map->{extent}->{maxy} -
$map->{extent}->{miny})/($imgheight - 1));
        $yimg = (($map->{extent}->{maxy} - $yvert)/$cellsizey);

        #add image coord. to the new list
        push (@imgshape,$yimg);

       }

    #form the <area> tag for html output
    $coords = join(",", at imgshape);
    $area = "\<area shape=\"polygon\" coords=\"$coords\"
href=\"URL-HERE\"\>\n";
    print STDERR "$area";
    push (@areas, $area);
}

The error message is a tad deceiving in that the word "Reference" should
not be there. It should read "Image map coordinate...".

Any way MapServer defines MAXCLICK and MINCLICK vars to detect 
potentially bogus input. These values are set to 1000 and -1000 right now.
With very large images or simulated pans using imgxy you could find them
too small. They can be bumped by editing mapserv.h. Your error means 
the values for imgxy your sending exceed those limits. Either your using large
images or some code is wrong.

(Note that were talking about image coordinates, and not map coordinates.
They represent a raw mouse click but can be set by an application to achieve
pan effects.)

As for zooms, let's see:

 using a user "click" (imgxy/img.x/img.y) you can use
   - zoom 
   - zoomdir and zoomsize
   
or you can use a user "box"

of you can use a user reference map click (ref.x/ref.y), but this is pan only

(if you've got map coordinates you can create maps with an extent, a point and
a distance, or a point and a scale factor)

In terms of precedence: imgbox, then img.x/img.y and finally imgxy. If the imgbox
resolves to a point it is not used and another method is found. Note that img.x and
img.y are set ONLY if the user clicks in a form <input type="image"...> element.

As for zoom controls pick one and stick with it. There is no precedence so mixing
them will yield unpredictable results.

Image coordinates are to be expected. Ref.x and ref.y are the coordinates of the mouse
click and are converted to map coordinates on the server. I think the problem is that you
haven't specified a size (eg. SIZE 100 125) in the reference object. It could be grabbed
from the image itself I suppose (requires opening the file an extra time) but at this point 
it needs to be hardcoded in the map file.

I'm trying to use my reference map as an input image that will pan the main map to be centered on the point that is clicked on the reference map.  When I click on the reference map, however, the coordinates for ref.x and ref.y appear to be in image coordinates rather than map coordinates.  I end up with a blank image for my main map.  Below is a snippet from my .map file.  Any help is appreciated.

Thanks,

Hi An,

I am also a newbie at UMN MapServer, I did ESRI MOIMS and SDE programming. I am
interested in having a look at your Java applet for client side interacting,
perhaps
some other fellows from newsgroup are also.

DO you share your knowledge...thanks in advance!

Cheers

I've posted 3.3.009 on the MapServer web site. It's mainly a convenience
release for users doing work on win32 platforms (thanks Daniel). If your
having any trouble with MapScript you should try this one. 3.3.008 contained
a naming problem that was not caught by the linker when building MapScript.

I will be updating system documentation to relect changes in .008 and higher
tonite.

Yup, the extent is recaclulated based on the shape of the extent and the window
size/shape. You are gauranteed to see the whole extent plus a bit more. The
algorithm fits your requested extent in either x or y dimension (whichever fits
best) and then pads the other dimension as needed. This has to be done in
order to get the right map to image transformation. You wouldn't necessarily
have to actually display data outside the actual requested extent but that would
result in a great deal of blank space in the resulting image, so the computed extent
is used to select/clip data.

Doing this is a little tricky but not too bad. The input page is straight forward, just a
normal MapServer type form. The key is how you process the request. 

In the mapfile you'll want to set the overall map status to OFF, this just tells the MapServer to process
the request but not to actually make the map gif. The map will get created in a second "mode=map"
request.

You'll also want to create a layer definition for the users point. It should have no DATA element but
should set up the correct symbol and fonting you want. It's status should be OFF. Lets assume you 
call the layer 'user'.

Now, normally in a MapServer template file you have a line that looks like:

<input type="image" name="img" src="[img]">

in this case you want to replace [img] with (assuming a layer called user):

/cgi-bin/mapserv?map=[map]&mode=map&map_user_feature=new&map_user_feature_points=[mapx]+[mapy]
&map_user_feature_text=[label]&layer=users&mapext=[minx]+[miny]+[maxx]+[maxy]

The rest of the template is as normal. In this case [mapx] and [mapy] are the coordinates of the users click.
[label] takes the value typed in by the user in the previous form assuming the name of that text box was
'label'. The nice thing about this approach is that since no has to be created initially the template loads
very quickly, then the browser fetches the map. The DNR Compass uses this technique. (see 
http://www.dnr.state.mn.us/compass/)

Clear as mud?

With mapscript, you can add points, etc.    Hope that helps.

Hi Steve,
I have a small problem and would like to discuss this here.

1. When I specify a bbox (lat, lon), then the result map should  fit exactly within this
BBox.
2. When I specify a width and height, the result bitmap should have this width and
height.
3. What is when I specify bbox and width and height? Then something is over defined!
    - I assume, the result should exactly fit in the bbox AND the bitmap should fit
exactly in one
      dimension width or height and the other dimension of the bitmap should be
calculated
      on the fly!
- I get something unexpected when the map server extracts the bbox, especially when I
like to integrate the bitmap into an other application and assume, that the bitmap has
the
bbox, that I used to generate it.

Is there any way to get what I assume in 3. !

Sincerely

Frank Lochter

The current behaviour, which is to create the smallest possible extent

the aspect ratio of the image, is as specified in the OpenGIS Consortium
Web Map Server specification.

A perl wrapper for mapserv to conform to the OGC specification is under
construction. We'll be putting it up on  public CVS site as soon as we
can.

Steve, I have asked this before - is it possible, and can you provide an
example, of specifying the projection to be used from the CGI
parameters?

Future plans include actually parsing the .map file to create the
"Capabilities Document" in XML required for OGC conformance. (Its
currently hand built)

Also, a modified version of the mapimage Applet that uses the OGC
protocol to get a base map and allows Javascript control of the extent
to fetch will be posted. Just need to check the copyright on the
original code to see if this is OK.

The community will be free to take these and modify them further.

Rob,  Where are the specifications for the OGIS server?
Yes, that is a goal we should be working towards...  
I'd like to at least read up on it and see what kind
of problems we can identify.

Maybe Doug Nebert, or someone else on the list can
give some feedback about the getting mapserver working
in with the OGIS Web Mapping testbed apps.

On the issue about aspect ratio, most a map server
software will adjust to best fit and meet the input bb
args. I make the assumption that the algorithms for
adjusting the aspect ratio will vary.  Is there is a
published specification for doing that?

Regards,

Chris

Vinod, and other MapServer users,

I think that the Windows utilities that were posted in reply to your
question a couple of days ago are probably the best option if you have
access to a Windows system, which is quite likely if you are dealing
with MIF files.

However, the OpenSource fans around will be happy to hear that there is
also an OpenSource/multiplatform solution coming down the pipe.  We have
at the moment a command-line utility that could be compiled on any OS
and could go between MIF, TAB, SHAPE, and a bunch of other formats, but
it's not very user-friendly yet, that's why I think the Windows
solutions above are still the best (if they really work!).

What I'm talking about is the OGR library, it is an OpenSource lib in 
C++ that implements the OGC simple feature specs (and supports SFCOM) to
give generic access to vector formats.  The OGR was written by Frank
Warmerdam (who also wrote the Shapelib that gives MapServer its shape
file access) and at the moment it supports a number of formats including
SHAPE, MIF and TAB.   One of the OGR test programs is a command-line
utility to go from one format to another, I could make a copy available
if anyone needs it.  

Also, one of our plans in the next few months is to implement an
optional MapServer module based on OGR that would give transparent
access to multiple data formats.  This will have to be coordinated with
Steve and would not replace the optimized Shapefile access, but for
those who are ready to pay a small price in performance, then this will
become a very interesting option.

For more information, the OGR web page is at:

If you force the mapsize or its aspect ratio to be twice 
as wide as it is tall (500 x 250) then it will do its best 
to fit the requested map into that space. if you experiment 
with always defining regions that are this shape, the request 
will work fine. The mapserver will never distort the coordinates 
to display within a specified mapsize, it will align with the 
smaller extent dimension and show more in the other dimension.

Hmmm. I wrote a nice detailed response to this on Friday. Looks like it never made
it to the list. Probably a DNR problem. Anyway, here's the skinny...

First of all I understand the problem. That said everyone must understand that the
MapServer was written (initially) to support interactive mapping. That is, interfaces
where the user would pan/zoom repeatedly. In that scenario image size needs to
be constant. You could change it (i.e. via mapsize=) but once set it was fixed and
the extent was massaged to fit the image size perfectly. When acting as an image
engine for other apps I can certainly see the value of supporting 1. as defined by
Frank below. Trouble is how to do that. An extent is not enough. In addition to the
extent you need either:

  - one image dimension, the other can be calculated
  - an image resolution, cellsize for which both image dimensions can calculated

Me thinks both should/can be supported. For case one I propose adding a new
mapfile parameter, something like FIT which would have to possible values- IMAGE
and EXTENT with the default being EXTENT. You'd still define a SIZE but only one
dimension would be used depending on how things are oriented. This is just like extents
are handled now. For case two i'd propose adding a new CGI parameter (cellsize) that
would be used with mapext in generating image size.

I can make these changes in 3.3.010 if it's seems ok to folks. These changes would
have no impact on existing apps.

There of course other alternatives:

  - you can use mapscript to generate image sizes based on extent yourself
  - the client application can do it

It should be noted that the assumtion that 'the result should exactly fit in the bbox' will almost
never be true even with the modifications discussed. The is because image sizes are integral
and computations often result in fractional (i.e. 525.345) results. However, with the changes
suggested about errors will be less than half a pixel which is as good as one could expect unless
you do work in the client application to ensure a perfect fit.

Hi Steve,

I have a small problem and would like to discuss this here.

1. When I specify a bbox (lat, lon), then the result map should  fit exactly within this BBox.
2. When I specify a width and height, the result bitmap should have this width and height.
3. What is when I specify bbox and width and height? Then something is over defined!

    - I assume, the result should exactly fit in the bbox AND the bitmap should fit exactly in one
     dimension width or height and the other dimension of the bitmap should be calculated on 
     the fly!

    - I get something unexpected when the map server extracts the bbox, especially when I
      like to integrate the bitmap into an other application and assume, that the bitmap has
      the bbox, that I used to generate it.

Is there any way to get what I assume in 3. !

Sincerely

Frank Lochter

Hi all

Just a quick note to say that mapscript (3.3.009)
seems to work fine with Python.

If anyone wants I can send them the
mapscript_wrap.c and mapscript.py
but swig worked on the first try

swig -strict 0 -shadow -docstring -dhtml -python -lembed.i -DPYTHON -module
mapscript -o ./mapscript_wrap.c ../mapscript.i

Peter,

That CGI variable error message you encountered refer to the mapserver
mapfile.  Since you are getting a CGI variable error, you at least have the
mapserv.exe in the right place.  You don't have to do anything special with
it except to start writing an application.  I suggest downloading the
MapServer demo for NT at http://128.101.73.80/ms_demo/ms_demo.zip and play
with it.  To see how the demo should look, go to
http://128.101.73.80/ms_demo.  You can also check the tutorial for MapServer
on NT at http://128.101.73.80.

These links should get you started.

Hi Steve,
thank you very much for your answer. I'd like to include my comments directly into
your answers. But first of all, I love your map server and would like to thank you for
the very good job you do here!
Unfortunately I wasted a lot of time with a GMT wrapper. It's fast, but not flexible enought.

May be it's enough, that only one dimension has be constant. Our "best practice" is
568 pixel horizontal  see: http://dc.gfz-potsdam.de/gis/  .

Why not only to check, whether there are width and height in the request and when
only one dimension is specified you can  calculate the second dimension on the fly.

I can live with that. But if you use e.g. the OGC (www.opengis.org) specification for map servers,
the idea is to use different OGC map servers to generate layers. You should be able to overlay
these layers from different map servers into one map. That's why, the BBOX has to be exactly
what was specified for the request to the map server.
We've a very poor interface to 2 map servers (under construction) following partly the OGC map
server specs  (http://dc.gfz-potsdam.de/~puchert/metaserver/mapserver_demo.html).
The wrapper for your map server (to make it OGC conform)  is from Rob Atkinson with some
of our own additions.
You can use the interface or you can use the URL's directly, that are beneath the "Request" button.

You are missing a map tag, and the map value is a path name not a URL.

Try something like
http://dgi/cgi-bin/mapwerv.exe?map=C:\inetpub\wwwroot\cgi-bin\demo_map.txt

You could probably get away without the full path,
http://dgi/cgi-bin/mapwerv.exe?map=demo_map.txt

Thanks to all who responded to my question. The ESRI command line utility
worked very well. Had it not been brought to my attention I would have still
been searching for it since it does not seem to show up on the ESRI website

Vinod, and other MapServer users,

I think that the Windows utilities that were posted in reply to your
question a couple of days ago are probably the best option if you have
access to a Windows system, which is quite likely if you are dealing
with MIF files.

However, the OpenSource fans around will be happy to hear that there is
also an OpenSource/multiplatform solution coming down the pipe.  We have
at the moment a command-line utility that could be compiled on any OS
and could go between MIF, TAB, SHAPE, and a bunch of other formats, but
it's not very user-friendly yet, that's why I think the Windows
solutions above are still the best (if they really work!).

What I'm talking about is the OGR library, it is an OpenSource lib in 
C++ that implements the OGC simple feature specs (and supports SFCOM) to
give generic access to vector formats.  The OGR was written by Frank
Warmerdam (who also wrote the Shapelib that gives MapServer its shape
file access) and at the moment it supports a number of formats including
SHAPE, MIF and TAB.   One of the OGR test programs is a command-line
utility to go from one format to another, I could make a copy available
if anyone needs it.  

Also, one of our plans in the next few months is to implement an
optional MapServer module based on OGR that would give transparent
access to multiple data formats.  This will have to be coordinated with
Steve and would not replace the optimized Shapefile access, but for
those who are ready to pay a small price in performance, then this will
become a very interesting option.

For more information, the OGR web page is at:
	http://gdal.velocet.ca/projects/opengis/index.html

The problem is you have the wrong syntax for JOIN.  JOIN is now used in the
same way as other objects in a map file.  That is you begin with the keyword
JOIN and end with END.  Here's how it should look, based on the example you
gave:

QUERYITEM usclass
QUERY
    EXPRESSION "421"
    TEMPLATE lakes.html
    JOIN   # start of JOIN object
        NAME water
        TABLE "lakejoin.dbf"
        FROM "islake"
        TO "type"
        TYPE single
    END   # end of JOIN object
END
QUERY
    EXPRESSION "^-"
    TEMPLATE land.html
    JOIN   # start of JOIN object
        NAME notwater
        TABLE "lakejoin.dbf"
        FROM "islake"
        TO "type"
    END   # end of JOIN object
 END
END # layer

Have a look at the map file docs (http://mapserver.gis.umn.edu/mapfile.html)
for other mapserver objects/keywords.

Carlo,

(I'll CC: my response to the MapServer list since other
MapInfo users might be interested.)

First of all, I would like to say that I can appreciate the fact that
MapInfo users would be extremely interested in using MapServer if they
could use it to serve their data directly.

Adding support for OGR in the MapServer would automatically provide
support for MapInfo TAB files.  There would be no gain in replacing the
shapefile support in MapServer by MITAB only.  Mind you, access to
MapInfo TAB files would still be quite efficient even going through OGR
since MapInfo files are quite well organized for random access.

The loss in performance that I talked about was due to the fact that OGR
uses a set of generic C++ classes defined to accomodate most formats
(while respecting the OGC Simple Feature specs), and as a consequence of
that, stuff like creating objects in memory for every feature that you
read for instance will never be as efficient as a direct C API optimized
for a specific format like shapelib.  And since MITAB is built on the
OGR object model anyways, accessing it directly will not require less
development effort nor provide much better performance than going
through OGR and support several other formats by the same way.

However, there is one thing that would have to be done in MapServer to
make MapInfo users really happy: the way MapServer works today, it could
not really take advantage of the symbology stored in a MapInfo file
(i.e. colors, line width, patterns, etc.).  So something would probably
have to be done to allow MapServer to use symbology information attached
to the data when it is available.  As part of OGR, I have started work
on specs for a generic way to carry symbology information between
formats.  So eventually the optional OGR extension for MapServer could
use that information as an alternative to defining CLASSes in the MAP
file.  How this would work exactly in MapServer is still undefined and
would have to be discussed with Steve though.

These are all very cool ideas that I would love to pursue but I have
only so much time in my hands... so I can tell you today that it is 99%
sure that MapServer will support OGR (and thus TAB files) before the end
of the summer because we have to do it for one of our clients.  On the
other hand, other changes in MapServer to take advantage of the
symbology coming from formats like MapInfo TAB will probably stay on the
ToDo list it becomes a priority for one of our clients... or if I find
the time to do it on a rainy weekend.  :-)

Best Regards,

Message-ID: <OFE1F63F9D.6FFA2131-ON862568A9.00692127@cr.usgs.gov>

Hello mapserv users,

I am trying to change map file parameters on the fly.  I understand I have
to use form variables, but there is not much documentation on how to use
them.  Here is what I am trying to do.  I have a polygon coverage of
watersheds.  The user selects a watershed by a mouse click.  From this I am
able to acess all the attributes from that polygon.  Now I want to use this
polygon's attributes to form a class expression and query expression on the
same polygon shapefile.   The output I need is a map with all the polygons
highlighted that got selected in the class expression.  Here is the HTML
code I am using, am I doing something wrong?  All it returns is the image
from the previous point query.  One problem I noticed is the [DOWNSTREAM],
[FROM_DON_], and [TO_DON_] get turned into the values of the polygon's
attributes that got selected from the mouse click.


 <form name="query_map" method="GET" action="/cgi-bin/mapserv.exe">
   <input type="hidden" name="map" value="[map]">
   <input type="hidden" name="imgext" value="[mapext]">
   <input type="hidden" name="map_layer_0_classitem" value="DOWNSTREAM">
   <input type="hidden" name="map_layer_0_class_expression" value
=(([DOWNSTREAM] ge [FROM_DON_]) and [DOWNSTREAM] le [TO_DON_]))">
   <input type="hidden" name="map_layer_0_class_color" value="255 255 0">
   <imput type="image" name="img" src="../watershed/temp_mapserv/[img]"
border="0">
   </form>

Does any onw have any suggestions?  Would this also be possible to do with
a URL instead of form variables?

Its a symbol set issue. I imagine the demo you downloaded was pre-3.3 and
has old symbol sets. Replace the file 'line.sym' in the ms_demo/symbols directory
with the one attached and give it another try.

On the expression front again the 3.2 demo is wrong. ^- is a regular expression
that means anything starting with a minus sign. Regular expressions should be
enclosed in //'s so change the occurances of "^-" to /^-/. Other expressions
are tests for equality and should be fine as is.

A new 3.3 only demo is underway. Yes, a book would be nice. Any co-authors?
How bout a user group meeting?

Message-ID: <s8d8e243.037@gwgate.dnr.state.mn.us>

Interesting problem. If all you want is the image then there is no need to
have another form. I assume you want some of the values in the expression
filed in and others left alone. (note: you don't have to provide a CLASSITEM
with logical expressions, it's ignored)

The problem is that MapServer sees the [DOWNSTREAM] and wants to 
replace it. One workaround might be to escape the []'s. Your page could
contain:

<img src="/cgi-bin/mapserv.exe?map=[map]&mapext=[mapext]&map_layer_0_class_expression=((&#91;DOWNSTREAM&#93;&#32;ge&#32; [FROM_DON_])&#32;and&#32;&#91;DOWNSTREAM&#93;&#32;le&#32;[TO_DON_]))&map_layer_0_class_color=255&#32;255&#32;255&mode=map">

In theory ;-) this should be the image you describe. It looks ugly but what I did is pretty
simple. Spaces and []'s  got replaced by their appropriate HTML escape sequences. [TO_DON_]
and [FROM_DON_] will be replaced by the MapServer but [DOWNSTREAM] won't since
it's not escaped. Note the mode=map at the end. It tells MapServer to only kick out the image
and nothing else.

Hello mapserv users,

I am trying to change map file parameters on the fly.  I understand I have
to use form variables, but there is not much documentation on how to use
them.  Here is what I am trying to do.  I have a polygon coverage of
watersheds.  The user selects a watershed by a mouse click.  From this I am
able to acess all the attributes from that polygon.  Now I want to use this
polygon's attributes to form a class expression and query expression on the
same polygon shapefile.   The output I need is a map with all the polygons
highlighted that got selected in the class expression.  Here is the HTML
code I am using, am I doing something wrong?  All it returns is the image
from the previous point query.  One problem I noticed is the [DOWNSTREAM],
[FROM_DON_], and [TO_DON_] get turned into the values of the polygon's
attributes that got selected from the mouse click.


 <form name="query_map" method="GET" action="/cgi-bin/mapserv.exe">
   <input type="hidden" name="map" value="[map]">
   <input type="hidden" name="imgext" value="[mapext]">
   <input type="hidden" name="map_layer_0_classitem" value="DOWNSTREAM">
   <input type="hidden" name="map_layer_0_class_expression" value
=(([DOWNSTREAM] ge [FROM_DON_]) and [DOWNSTREAM] le [TO_DON_]))">
   <input type="hidden" name="map_layer_0_class_color" value="255 255 0">
   <imput type="image" name="img" src="../watershed/temp_mapserv/[img]"
border="0">
   </form>

Does any onw have any suggestions?  Would this also be possible to do with
a URL instead of form variables?

Thanks,

Um, er. Forgot to update the docs for this one. Embeding works for scalebars
at this point. The EMBED parameter is not used rather you set the STATUS
to EMBED. You MUST have a markerset defined to use embedded scalebars.
They are actually added as a symbol and rendered using the noramal marker
utilities. Here's a typical definition:

SCALEBAR
  STATUS EMBED
  LABEL
    SIZE tiny
    COLOR 0 0 0
    OUTLINECOLOR 255 255 255
  END
  STYLE 0
  INTERVALS 3
  SIZE 100 3
  COLOR 0 0 0
  BACKGROUNDCOLOR 255 255 255
  OUTLINECOLOR 0 0 0
  UNITS MILES
  POSITION LR
  TRANSPARENT TRUE
END # Scalebar

TRANSPARENT turns the image transparent. POSITION is similar to POSITION for labels.
Supported positions are UL,UC,UR,LL,LC,LR. Attached is an example image with an
embedded scalebar using the above definition.

Does the EMBED parameter still work for legends and scalebars?  I haven't tried it with a legend, but when I add 'EMBED true' to my scalebar parameters in my .map file, I get:

loadScalebar(): Unknown identifier. (EMBED):(67)

I don't know that I'd use it.  Just wanted to see how it looks.

Doug: Cool. It is simple although a bit cryptic. A couple of questions:

  - got any example urls for calling the ms.pl script?
  - where/what is the required file dumpvars.pl?

Seems the capabilities.xml file would be best built from the mapfile itself. I believe
most of the params presented in the the .xml file are accounted for in the mapfile
syntax. MapScript would really simplify that process. It could be used to simplify the
getMap request by avoiding any CGI altogether. MapScript also supports queries
now so a getFeatureInfo request should be easily doable. In addition, you have
direct access to the shapefiles in MapScript so dumping vectors as SVG or whatever
can be done too.

Anyway, nice work Rob/Doug. Looking forward to learning more about this capability.

I have modified the http://clearinghouse3.fgdc.gov/wmswrapper.html
to reflect the necessary files and an example invocation. The 
dumpvars was a diagnostic include and was commented out, now it is 
not in the ms.pl file.

I like this idea and would encourage any takers to show us how 
mapscript could really be used to do this. There are a number of 
useful values (Name, Title, Abstract) for each layer that may not 
have a counterpart in a map file (only Name) and are really useful 
for searching and evaluating the available layers in a catalog. 
Perhaps these could be gleaned from legend-like constructs in a 
future mapfile?

I am confident this can be done for both raster and vector 
targets under mapserver, just not yet implemented. As the 
XML-encoded vectors stabilize in OGC's GML proposal this would be 
a very cool output feature to demonstrate among the FGDC and other 
pilot projects in the coming 6 months.

Hello,

I have not looked at Mapserver in depth yet, but need to determine if it
will be suitable for the application we have in mind.

The application would allow a user to input values at the web page and have
those values determine which data to attach to the shapefile. Based on the
variables, the appropriate legend, title, etc would be selected/constructed
for the map as well. This would allow the creation of a large number of
different maps with relatively little work being done. We want to avoid
having a seperate file or set of files for each individual map to be
produced (that is currently the case with ArcView IMS and likely to be true
with ArcIMS as well).

Is there a mechanism whereby attribute data residing an a database (eg. MS
Access) can be joined to a shapefile, which is then used in the creation of
a custom map on the fly? (the legend would apply to the joined attributes)
OR
Does the data have to be merged with the shapefile .dbf component? (I saw
some posts to this effect in the archives from November)

I will not be in the office on Friday, so if I do not reply to messages by
the end of today I will have to get to them on Monday.

HI all-
Two basic questions:

   With every submit the "map" drifts to the lower right, eventually going
   off the image area. I realize its California, but ... I have tried
   changing the map extent to no effect. Do I really need to crank down
   the map extent to acheive the centering I desire or is there another 
   solution?

2) In unix/linux: When I implement freetype, etc as part of MS, do I need
   to make a library path change so that these will function- they don't
   now, I get an error if I uncomment them now. Could someone post a
   sample so that I can try it out if this something that I need to do.

Thanks in advance,

Check your html template to make sure that img.x, and img.y exist and
default to the center of your image (1/2 the dimension).

I suspect that img.x and img.y are both too big in your template which is
causing the drift.

Mapserver doesn't support Access, but you could dump your access database to
.dbf
A periodic script could be written to dump your Access database to .dbf

With the standard package the attributes must be part of the shapefile.
You can get around that by using MapScript. and processing shapes
in turn within the scripting environment. Hopefully most base layers would
not have to handled this way so the performance hit wouldn't be that
bad.

Hi there,

I'm a new user and have just finished installing ms_3.3.009 on my Linux
system. The install went off without a hitch but I am having a few
problems with the demo file. I was able to fix most of them but I'm now
presented with the following error,

msSaveImage(): Unable to access file. (DEMO954150496700.gif)

when I initialize from the demo_init.html. I've done a search through
the archives but found nothing. Could it be that the script is trying to
write the above-mentioned gif but having permission problems? Thanks,

Anyone have a methodology for a compile of mapserv using 
the Cygnus gcc compiler for win32 or lcc compilers?  Both 
are free C++ environments for the Windows environments... 
Or do we need to go patronize Redmond? I haven't done 
much with either of these but have experimented on some 
light programs using the gcc stuff. It allows ports of many 
UNIX programs destined for the gcc environment.

a quick chown or chmod shoud do the trick

mapserv compiled out of the box for me with Cygnus toolkit
updated to use the gcc-2.95.2 compiler and the Dec 15 1999 dll
and the /usr/local distribution from
http://cygutils.netpedia.net/ 

I would imagine that the V1.0 cd distribution would
work also.

FWIW
There is a pending release of a new Cygnus distribution
that should work as well.  I would recomend waiting for it
if you do not have an augmented Cygnus system already.

I did not try to compile the Perl version of mapscript
but I did compile a Python version successfully.

I would recommend the Perl distribition also from
http://cygutils.netpedia.net/ 
for those trying to compile a Cygnus Perl mapscript.

 Hi there,

 I am not sure at what stage you are (meanning if you already have your
libtiff.lib build already).

In any case the best thing I can do is to refer you to the zip files
 http://www2.dmsolutions.on.ca/mapserver/ms_vc_makefiles_v3.3.009.zip

containing the makefiles necessary for mapserver to link properly with Tiff
and Freetype librairies.

I have added in this zip a file called COMPILE_MAPSERVER.vc with basic
instructions on steps to follow.

Perhaps a special note for those who do not want the freetype version but the
libtiff, you have to edit the makefile.vc (the one in the main mapserver
directory) and comment out any referenece to freetype library (all thinks
related to TTF and gdft should be removed).

If you still have a problem, please let me know what exactly are the errors.

I have also put a mapserver.exe binary file with tiff and true type support
for those who needs it.

 http://www2.dmsolutions.on.ca/mapserver/ms_3.3.009_win32.zip


Hope it helps,


Best Regards.

Message-ID: <OF63D8E004.95400649-ON862568B0.006F5A99@cr.usgs.gov>

I want to thank Brent Fraser and Assefa Yewondwossena for helping me with
compiling mapserver for NT with freetype and libtiff.  I'm sorry I did not
try Brent's instructions, but they look like they would work just fine.  I
used Assefa's makefiles for Visual C++.  For anyone else that is new to
using Microsoft Visual C++, like myself.  I think it might be important to
add this to Assefa's step four:


These are insturctions to compile Freetype:
 - Open Visual C++

 - Open Workspace (File Menu) : ./freetype/lib/arc/win32/freetype.dsw. It
is a visual project file
(containing all the refernece to the source code).

 - Once it is loaded you go in the menu Build and you should see Build
freetype.lib. Select that and
it is supposed to build for you the library. I beleive the libaray will be
build in the directory
./freetype/lib/arch/win32/debug/freetype.lib.

- Once it is build, copy this library in the directory ./freetype/lib; this
is because the makefiles
from mapserver that I sent expect to find the freetype.lib in that
directory.

- Last step is to build mapserver using the command nmake /f makefile.vc in
the mapserver main
directory. There is also a readme.vc file for reference.

Thanks again,

Hi,

I had similar experiences with 3.3.006 when rendering an image (with no

further than deleting the .qix files. I was using a WinNT/mingw32
platform.

Hi Markus,

Not too clear what you are attempting to do, but here is the essense of
extracting RGB values from ODB/AVL storage format, according to our
Avenue-guy.  I assume you have ArcView (I wasn't sure from your
message).  Script1 essentially creates an ODB with color values in it
and then Script2 extracts them...hope this gets you started.


/////////////////////////////////////////////////////////

'Script Number 1:
'Writes colors out to an ODB.  Colors are stored in ODB in hexadecimal
format.
theODBFN = "$TEMP\colors.odb".AsFilename
theODB = ODB.Make(theODBFN)

the1stColor = Color.Make
the1stColor.SetRGBList({212, 155, 96})
theODB.Add(the1stColor)

the2ndColor = Color.Make
the2ndColor.SetRGBList({21, 15, 9})
theODB.Add(the2ndColor)

theODB.Commit


'Script Number 2:
'Reads colors in from the ODB created in Script Number 1.  Displays the
RGB values (GetRGBList) in a MsgBox.
theODBFN = "$TEMP\colors.odb".AsFilename
theODB = ODB.Open(theODBFN)
the1stColor = theODB.Get(0)
the2ndColor = theODB.Get(1)

MsgBox.ListAsString(the1stColor.GetRGBList, "First Color in ODB",
"Color")
MsgBox.ListAsString(the2ndColor.GetRGBList, "Second Color in ODB",
"Color")

This can't be done as the current code sits. The truetype symbols are
simply annotation (ie. like a city name) and are not used in legend 
building. The symbol set would need to be extended to accomodate
truetype fonts for this to work at all. It's doable, for markers anyway but
just hasn't been done yet.

Mapserver users:

I am using a pre-compiled version of Mapserver for NT (Thanks to Assefa
Yewondwossen and Brent Fraser) and it runs fine. Now I need to get Mapscript
working. How do I do this?

If I try to compile Mapserver from scratch using CygWin B20 I get the
following errors (I did not modify the Makefile in any way):

You need to install the freetype library

You need to install the regex library
get it from any gnu archive

At this stage, I need to determine if Mapserver will be suitable for our
purposes. A pre-compiled Mapscript would save me much time.

I am using ActivePerl 613 (based on Perl v5.6.0).
