To date, I've always been able to get my rasters to handle
transparency by converting them to PNG files. Now, I'd like to
know if there really is another way to do this using TIFFs, for
example. In my case, I've got some really large air photos that
are currently TIFFs with pyramids with "No Data" set to 0.
If I convert those to PNGs using FWTools, I can get the
transparency to work, but the moment that I build my pyramids, I
lose the transparency in MapGuide (likely because the pyramids
seemingly need to be in JPG or TIFF formats). So, this leads me to
try to figure out if there's a way to do it with the original
files now.
My files are 8-bit RGB, with pyramids and the color that I'd like
to be transparent is black. Is there a way to do this? I've
checked back through the group for answers on this already, but
really can't find a clear answer one way of the other. Thanks in
advance!
