[Mapserver-users] Layer TRANSPARENCY and 24bit

[Frank Warmerdam]

Folks,

I have committed fixes to the msImageCopyMerge() so that 24bit images
have the same sense of TRANSPARENCY as 8bit.  I stuck to the logic as
used in 8bit and documented (0 = transparent, 100 = opaque) even though it
might be somewhat counterintuitive.

I have updated the testsuite to validate transparency better ... I did all
my previous work with 50% and so missed this issue.

Best regards,
