[Mapserver-users] Problems getting mapserver to run w/ bitmap images

Bernhard -

First, please "Reply to all" on list messages so everyone can participate in the discussion.  The first person to reply to a message isn't always the right person to continue solving the problem.

The first thing you need to do is start generating PNG images that aren't all white.  That symptom means that you are correctly generating a map, but you are not requesting any data layers that are visible in the map area you request.

You need to get your georeference data sorted out.  Is your TIFF image a GeoTIFF with geographic reference info, or do you have a world (TFW or WLD) file for it?  You need to set an EXTENT in the MAP file or request it on the querystring to specify what area you need.

Hi, 
thanks for your fast reply - however, it doesn't fix the problem. 
I've debugged things a bit further: 
- A png file in the temp directory is actually generated, it's the correct size, but it's all white. 
- The size of the map window on the mapserver generated page is still 1x1 pixel. Pointing the browser at the 
generated PNG image gives the expected results (large all-white picture), so it's not a matter of the browser 
no supporting PNG or something. 

Any ideas? 

Thanks, 
Bernhard
