Windows CE only supports the following raster operations in the dwRop parameter.
SRCAND
SRCCOPY
SRCINVERT
SRCPAINT
Windows CE 1.0 only supports two bit per pixel (maximum) gray scale graphics. When performing a bit-block transfer that converts two bit-per-pixel (2bpp) to one bit-per-pixel (1bpp), Windows CE 1.0 maps the background color to white, and all other colors to black. When converting from 1bpp to 2bpp, it maps white to white and black to black, as expected.
