Whose bright idea was it to write an image handling library with callbacks?
Why so many functions as options?
Why do you have to guess whether it's bits per pixel or bits per colour?
Why can I hear Hallelujah blasting from my neighbours' garden?

Ugh!

Yet another open sores failure

PNG is a great image format, but libpng is a clusterfuck. It's depressing.

What the hell... I need to check this out for myself.

Correct me if I'm wrong, but isn't the use of callbacks in libpng entirely optional?

Don't get me wrong, a while back I took one look at the API and said fuck this shit, but I do tend to appreciate the option to use callbacks.

Actually I tend to think libpng is pretty awesome.

The only thing I wish it had is a *really* high level API. You know, the one where you pass it a char* filename and it returns a void* buffer of rgba pixel data. The one everyone writes around it to use for their own purposes.

Call them delegates if it makes you feel better.

LOL.. Somebody should slap that idiot on his face. He should've just quit and go fishing or something. There actually another png library out there but less feature and not supported anymore.

another thing that stinks about libpng: they came up with an animated format called MNG that only firefox bothered to implement support for. the format was deemed insanely complex. eventually, firefox scrapped it in favor of APNG... a simple animated format that added GIF like abilities to PNG. libpng refused to accept APNG thinking that their bloated MNG was superior.

if, however, they were to accept the APNG patches, every browser would eventually have support for APNG, and that would mean we could actually have an animated image format superior to GIF -- with better compression, more than 256 colors, alpha transparency, etc.
