[Mapserver-users] raster layers in PDF output don't get cropped

[Yewondwossen Assefa]

I havn't really seen this with the test files that I am using with 
Mapserver 4.1-dev gd-2.0.15 and pdflib-4.0.3 (on a Windows platform). Is 
it possible to isolate this to one or so raster layer and send me 
directly the map file and the data so I do additional tests ?
