Returns the CRC value of a bitmap file. If the parameter mask is provided and is not null, only the masked pixels are used for the CRC calculation. The mask must be a monochrome bitmap with the same dimensions as the image. Black pixels hide the pixel on the same position in the image for CRC calculation.
lValue = GetBitmapCRC (sFileName, sMaskName)

| sFileName | The path to the bitmap file. Can be either an absolute path or a path that is relative to the current working directory. |
| sMaskName | The path to the mask file. Can be either an absolute path or a path that is relative to the current working directory. |
