Comments

LBitmap::StartFastMagicWandEngine must be called before calling LBitmap::FastMagicWand and LBitmap::EndFastMagicWandEngine.

When the handle to the MAGICWANDHANDLE is no longer needed, it should be freed by calling LBitmap::EndFastMagicWandEngine. For every call to LBitmap::StartFastMagicWandEngine there must be a call to LBitmap::EndFastMagicWandEngine.

This function supports 1, 8, and 24-bit images.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
