mixture of perl/mapscript and mapserver

[Joseph Norris]

Ed,

So in the scenario you mention below.  I would get a blank img that I could
lay layers on top of?  Currently I am pulling in the map file and adding new
layers to that.

#Joseph Norris (Perl - what else is there?/Linux/CGI/Mysql) print @c=map chr
$_+100,(6,17,15,16,-68,-3,10,11,16,4,1,14,-68,12,1,14,8,-68,4,-3,-1,7,1,14,-
68,-26,11,15,1,12,4,-68,-22,11,14,14,5,15,-90);

Joseph -

No, you're mixing apples and oranges.  Running MapServer through your
$url HTTP GET request simply fires off a different, completely unrelated
instance of MapServer.  IF you created a template file that consisted
solely of the single line

[img]

Then that HTTP GET request (executing MapServer) would return to you
nothing but the URL pointing to the map image it just created.  You can
then load that image file separately and do whatever you like with it.

But there's no "IMG" querystring variable to pass the name of an image
file - IMG.X and IMG.Y are CGI variables for passing the coordinates of
a mouse click.

Everyone,

I have the following bit of code:

$layerObj->draw($map, $img);
$point_layer->draw($map, $img);


my $new_map = "$png_location/" . sprintf("mx%0.10d",rand(1000000000)) .
".map";

$map->save($new_map);

my $image_name = "$png_location/" .
sprintf("map%0.10d",rand(1000000000)) .
".png";


$img->save($image_name, $map);

$img->free();


my $url = qq!http://$domain/cgi-bin/mapserv!;
   $url .= "?map_web_template=$template_path/map_template.html";
   $url .= "&zoomsize=5";
   $url .= "&zoomdir=1";
   $url .= "&zoom=2";
   $url .= "&map=$new_map";
   $url .= "&map_web_imagepath=$png_location/";
   $url .= "&map_web_imageurl=/$http_png_location/";
   $url .= "&root=/maps/";
   $url .= "&img=$image_name";
   $url .= "&program=/cgi-bin/mapserv";
   $url .= "&imgext=5890870.385 -192053.200 8943310.847 3226086.749";
   $url .= "&mode=browse";


I thought that upon the run of mapserver in my map_template_html I would
be able to load the [img] via the &img=$image_name.  However when it
loads I am getting a whole new image that contains nothing and is not at
all the same name that I have built.

I am not sure how to mix these - I would like to start out building my
own layers  ( which I have been able to do - thanks to all of your help
), save these out in an image and the load this into mapserver so as to
have the browse capability.

Have I made myself clear as mud?

Thanks.
