[mapserver-users] Invalid pdf file from WMS

[Worth Lutz]

I can get php MapScript to segfault drawing PDF maps when the same PNG map
works fine.  I had to crank up the allowed memory and allowed time in PHP to
get my maps to work.  I will submit a bug report and test case when I
understand the problem better.  I am trying to develop a method of creating
a large set of PDF maps dynamically with PHP and and am finally figuring it
out.

this seems to be a cairo/pdf issue, as the cairo/png works fine:
http://188.64.1.61/cgi-bin/osm-mapserver_i?REQUEST=GetMap&SERVICE=WMS&VERSIO
N=1.1.1&WIDTH=1728&HEIGHT=1324&LAYERS=default&TRANSPARENT=TRUE&FORMAT=cairop

what cairo version are you using? can you upgrade it?
