That function seems to do ONLY png decompression of a frame received through its parameters.
But what I didn't find is how that frame is assembled from fdAT and IDAT chunks.
I also tried that library in Lazarus but couldn't make it work.
@Luckie
The reason my code isn't working is not because is buggy, is because is not finished. And is not finished because I can't find more detailed informations about the apng internal structure and/or find simple examples in Delphi/Pascal code to show how is done.
I knew my code will not work from the minute I started working on it. But I was hoping one of you will help me finish it.
A
paradox: you don't seem to understand my code, which is so simple and short compared with that library function.
But I am suppose to understand a 3..4 times bigger and more complex function from a dozens times bigger and more complex library?
You guys are great helpers but unfortunately you know nothing about png animations.
Thank you and goodbye.
