I'm fairly irrelevant to game graphics, but I do have a question that perfectly fits here. I want a function that given an Image and a trapezoid defined by a four points array (or similar), will transform the original image to fit the destination quadrilateral. Actually, gdiplus has something close to what I want, DrawImage, but the destination there is a parallelogram defined by three points (the fourth is computed from the other three). Btw, I'm a VB.NET developer (...), but C# code should be fine too.
Thanks in advance
