Hi,
I have a pBitmap that I want to duplicate ( BitmapHandle and also duplicate the image bits).
The source of BITMAPHANDLE is TYPE_USER ( I maintain the memory buffer).
Could you show me a sample code how to duplicate it ( duplicate also the data/image bits) so to have destination also of type TYPE_USER.
Thanks,

Patrick

Patrick,

The steps are:
- Call the L_CopyBitmap2 function with the TYPE_USER Flag.
- Allocate a memory buffer with the same size of the bitmap data and copy the pixel data to the new memory buffer.
- change the data pointer of the bitmap to the new memory buffer by using the L_SetBitmapDataPointer function.

Thanks,
