[Geomoose-users] Printing wms layers

[Jim Klassen]

If the quality is different between PNG and GIF you are probably using PNG24 (as PNG8 and GIF should be identical image wise).

My guess is a GD bug dealing with PNG24.  I'm not sure what your options are, but it sounds like the print.php needs to be rewritten with a more modern library.

They work perfectly in GeoMoose map view.  But when I compose a printable map, these layers have a black background which obscures other layers and just plain looks ugly.  If I set the “transparent”  property to false, the black background goes away, but then I can’t see any underlying data.
