[Mapserver-users] problem with IMAGEMODE RGBA

[Matt Doggett]

No.  I can setting IMAGECOLOR has no impact on the resulting gray shaded
areas.  I've found a couple more tidbits:

* Changing OUTPUTFORMAT to 24-bit JPEG solves the problem
* Changing label TYPE from TRUETYPE to BITMAP solves the problem with
the bogus gray boxes around the labels (though it does nothing for the
grayshade in the legend icons).

Soooo, the problem appears to be pointing to the 24-bit transparency and
PNG images.

I haven't used 24-bit color yet, but does it have to do with the
specified map IMAGECOLOR?
