And what is the difference between gflBitblt and gflBitbltEx ?
Maybe the second one change the alpha channel too ?
I'll search some information about invisible watermarking... if someone knows about this
I use gflAddText. I'd like to add transparency to the text.
Is it possible to add this feature using the alpha channel of the text color?
Is there any function to get the text's size given a selected font (gflGetTextRect)?
