Hi All,
Is there a way to check if a GIF image has transparency set and if so what
the colour index is.
I'm trying to create thumbnails (which is working fine) but I'd like to
create a thumbnail from a transparent GIF with the transparency set in the
thumbnail the same as the original.
TIA,
Jeremy Coates
