TIFF displays and displays not

[Ed McNierney]

If I recall correctly, the INPUT=TIFF support reads GeoTIFF but not TFW
world files.  Exporting the file as a GeoTIF would then fix this
problem, consistent with your observation.  I'm not sure my memory is
correct, but the "built-in" TIFF support is now deprecated and you
really should remove it - GDAL will provide much better TIFF support for
you.

Thanks to everyone for the feedback. 

It seems to be a problem on the image side. I don't understand why, but
although it displays nicely in ArcView and Photoshop, the screen keeps
blank with Mapserver. (I had the impression that ArcExplorer-Java for
Mac didn't display it either.) But when I exported the TIF in ERDAS as
GeoTIF and loaded it into the app it worked.

                thanks for that. 

                Still, I can't see the reason for that. I have two TIFF
images, which 
                seem to be perfectly similar. I have saved them both
from Photoshop. So 
                no GeoTIIFF, only normal TIFF. 

                How do I get the "mapserv -v" on a Windows machine? 


        Change directory to your cgi-bin and type 
        mapserv.exe -v 


                The Linux machine is giving me this: 
                MapServer version 4.0 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=PDF 
                SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER
SUPPORTS=WMS_CLIENT 
                INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=POSTGIS
INPUT=OGR INPUT=GDAL 
                INPUT=SHAPEFILE 


        Recently I had trouble on Linux, having both native INPUT=TIFF
and 
        INPUT=GDAL. The gdal tiff support is more powerful then mapserv
native 
        solution so configure mapserverver --without-tiff and
--with-gdal. 
        I check my windows mapserv.exe which I downloaded in a binary
pachage, and 
        no INPUT=TIFF support involved.

                        The first thing I'd do is run "mapserv -v" on
each machine and look 
                        for configuration differences in your two
MapServer installations.  
                        Also, check whether both are GeoTIFFs.

                        Hi, 


                        gush, what a strange thing. I have to TIFFs with
a worldfile each. 
                        Using PHP/MapScript, on my windows machine, both
display nicely. On 
                        our Linux machine however, only one of the two
displays. When I select 
                        the other, white space... Nothing. 


                        I added one of the TIFFs only now, the other
already a couple of days 
                        ago. Sure, this can't be the reason. But ....
Actually, I have no 
                        idea. They are both 8 bit, and RGB color mode. 


                        Any idea whatsoever? Thanks for letting me know.
I am really stuck...
