[Cartoweb-users] ExportPdf Problems with AGG Rendering

[Dahinden Adrian]

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?

Adrian

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.
