Hi, I tried it and I find it amazing ... I have developped a small application in C++/WTL but I would like to rewrite it using this new framework. I have some questions, what is the license ? Can I develop some commercial software with it ? I see that your are using zlib, libjpeg, libpng but you could reduce binary size because it's already possible to manipulate this kind of image on wince(see IImaging) without third party libs.
