png decoding
Hallo,
I am trying to decode the png format, but the result is not correct.
Anyone knows how to do that? It is applied the paeth algorithm, which is a combination of the byte above, the byte on the left and the upper left byte, but the reconstruction is not correct.
Thank you
Isabella

Re: png decoding
And how do you get/read these bytes from a "pdf file"?
