I need a method made for me to use in .net projects that will let me write out a filetype of png8. Right now i am able to write out a png but it is not a png8 file so it ends up a lot larger file size than it needs to be. I want well commented logical code, something high performance and most likely something i can open source in the future. So i think this is easy but i want it done right so please make sure your approach is good and well thought out let me know if you need help understand the png differences. also if you know a lot about png file types maybe you can propose to me some other controls we can have over png. I will agree to them and pay for them in this project ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?

Hello, I suggest using .NET Graphics (GDIplus) API for the purpose. However, you should take into account that 8 bit PNG format won't support transparency. Is that ok with you? I'll be able to show you a simple demo if you are interested to work with me.

Hi, I'm Matt and would like to help you (23 years an IT developer and a webmaster, even longer than that using and researching digital image formats including fractal compression and wavelets). While I'm in other "waters" now and have to do other tasks for living (I graduated in MPEG-7, ISO specifications for semantically describing multimedia with XML) I believe I can work on the code. PNG has its freely available code so this is the first I want to ask - what do you use right now? Now for my opinion - I used to work with LEADTools, the fastest (commercial) image compression library few years back. That is probably not an option for you - due to licencing price - yet it offers easy path to incorporate image support in any Windows application. Either way,, looking forward to discuss. Sure, PNG-8 images should be much less in size compared to its PNG-24 saved same image. So maybe your library or calling the functions have some issues that needs to be researched and fixed. And generally - I am more Delphi an Java developer so have mostly mentored C(++/#) developers in the past. Though any programming language is not an issue if functions to use (other) code are required to fix, change and optimize. Regards, Matt
