How to rotate Bitmap in windows GDI?

How would I go about rotating a Bitmap in Windows GDI,C++?

Solution

  • You can do it with GDI+ (#include <gdiplus.h>). The Graphics class has the RotateTransform method. That allows arbitrary rotations. Use Image::RotateFlip() if you only need to rotate by 90 degree increments, that's a lot more efficient.
