Remarks

The graphics object of .NET does not support operations on 1bpp indexed Images. One solution is to convert the image to Format32bppArgb and then use the graphics object. Obviously this is slow. With StretchBlt you can use the Windows API to directly draw a 1bpp image to a device context (for example to print the image).
