I don't really know how to explain it in a better way, so please look at the following images :
I am currently using C++ with Qt 4.8.
Do you know a way that would allow me to reach my goal ? Using a library or a transformation matrix ? Or something else ?
I am a total newbie to image manipulation, so every advice is precious for me.
I draw each colored pixel from Lat/Long measures, if it can help.
