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

[Michael Schulz]

Hello Mr. Schönhammer,

are you using imagemode "image/png;24bit mode" for this service in
Mapbender? Then this could be the problem, because printPDF sets the
imageformat for the maps and the legend icons to image/png. Then maybe
your customized outputformat isn't used anymore... In the GUI the
imageformats are used as defined in gui wms settings.

Chees, Michael Schulz
