 <p>A Microsoft Windows icon file contains one or more images, at
 resolutions up to 256 by 256 pixels and various bpp values.  The
 images are encoded either as Portable Network Graphics file (PNG), or
 in a format similar to Microsoft's BMP format.

 additional 8-bit transparency data together with the color
 information.

 Except for the 16 bits per pixel images and images with bit fields, which both
 are rare, the colors in all BMP encoded images are RGB with 8 bits per
 channel.  Images with bpp values lower than 16 use a palette.

 understood by looking at how a 1-bpp icon image is rendered on a
 monochrome screen: The pixels on the screen are logically AND-ed with

 bits on the XOR mask.

 on the XOR mask determines the color of the pixel on the screen.  If a bit in
 the AND mask is set and the corresponding bit in the XOR mask is black
 (reset), the image is transparent.  Finally, if the bits are set in both the
 AND and XOR mask (the pixel on the XOR mask is white), the background of the
 screen is inverted.
