[Mapbender-users] MB 2.5: Problems with legends in pdf-print using mapserver's agg

[Michael Schulz]

Hi,

the problem with 24bit rendering is, that mapserver publishes that as
"image/png;mode=24bit" in the wms getcapabilities if you don't define
a special outputformat. So, when you have set image/png as
image-format in mapbender and you get a 24bit png back everything is
perfect.

Have you tried setting $unlink=false in printPDF.conf and then examine
the temporary images while generating the pdf output? I am not sure,
if this has impact on the legend images, but it could be worth a try.

Cheers, Michael
