#2 Make pngnq API

[Øyvind Idland]

Is there any plans on making an API to pgnnq ?

This quantizer is quite useful, and I believe turning it into an API would make it even more useful.

If I wanted to add the algorithm into my own software, I would have to carve out lots of code, remove global variables etc.

My wishes would then be, making a libpngnq and make the executable a simple program that links with it. In my case I already have a RGBA chunk in memory, so I wouldnt need any file I/O.

I could even put a helping hand into it!

This is a good idea. I'm looking at the tracker patch item 2521477. I think it may be a good time to
create an API from the code submitted there. Give me a couple of days...I'm busy at the moment.

Nice, looking forward to it :)

PS another (simple) feature I would like:

Would be be possible to have an option, where fully transparent
pixels would have highest priority ?

In my case, I am rendering graphics on a 100% transparent background. In
some cases maybe 95% or more of the canvas is covered, leaving small corners
and holes of transparent pixels. I need to keep these small holes 100% transparent,
and make sure that these dont get quantized into 10% opacity instead of 0.
Maybe this is already taken care off.. hope this makes sense :)

Thanks!
