An integer contains four … WebAn individual byte here signifies a pixel ‘s cost and the duration of run. The LMB (Left Most Bit) determines shade inside the 8 bits (e.g. 1 = white and 0 = Black) the run length is defined by the next 7 bits. Example: 32-pixel segment from a monochrome bitmap: The representation of the uncompressed will be.
