Hello friends,
I'm trying to extract the color data and alpha from a PNG image. In PHP
it is very easy to implement, but in FPC I don't know how to do it. I
tried to do it via "chunk.data", "ZData" etc., but, without success.
The question is what information are you looking for ? The compressed
PNG data, uncompressed, palette applied or not... I doubt that you need
the raw uncompressed bitmap.
That PHP code is a toy and can handle only a subset of PNGs.
