	)

Copy block of image data into the bitmap.

Assumes that the Bitmap has been constructed with the desired size.

Parameters

pData	The block of data to copy
nStride	The number of bytes in a scanline, must >= (width * nBitCount / 8)
bReversColors	In case the endianness of pData is wrong, you could reverse colors

Assumes that the Bitmap has been constructed with the desired size.

Parameters

pData	The block of data to copy
nStride	The number of bytes in a scanline, must be >= (width * bitcount / 8)
