specifies the color of each successive pixel to the right. This process continues for WNum bits and
pixels. Bit number WNum specifies the color of the right-most pixel on the top-most line.
Bit number WNum+1 specifies the color of the left-most pixel on the second line from the top.
Unlike most raster image formats, the PAL raster image format does not include any unused bits
between the last bit of one line and the first bit of the next line.
PAL treats the most significant bit of each byte as the first bit of the byte. PAL treats the least
significant bit of each byte as the eighth bit of the byte.
The following table illustrates the bit numbers for each pixel in a 10 by 10 pixel raster image.
