[Cartoweb-users] ExportPdf Problems with AGG Rendering

[Oliver Christen]

i see nothing wrong with your outpuformat,
it would be more interesting to get a more precise error message before 
tring to do some blind investigation
it is quite annoying to simply get a blank page.
dont you have anything in apache error log ?



Hi Bruno

Do you mean the images which are attached in the mapfile (rasterfiles) or 
the generated images from mapserver in /htdocs/generated/images/ or ..?

And how do I configure the OUTPUTFORMAT in the mapfile so that the printing 
works and the map will be rendered by AGG?

Just check if you have any image file with transparency (16/24bits).
It's supported by mapserver/agg but NOT by the fpdf library without big 
hacks.

Soluce is use a special non transparent file (logo,whatever you use) for 
printing.
