[mapguide-users] Transparent Rasters in Mapguide Enterprise 2010

[Mark Nichols]

Yes, last week I had problems with bi-tonal TIFF¹s.  I had a reply from a
member of the list instructing me to use Irfanview and convert the TIFF¹s
the PNG¹s.  It took a little work but yes, it did work.  I do now have
transparent images in MapGuide.  There were a few steps in Irfanview that
I¹m not remembering.  If you have problems, repost and I¹ll try to step
through the process again.
