   This is almost three formats in one:
   
        Low resolution:

           The planes are arranged vertically, instead of horizontally.
        The first byte is the red component of pixel (0,0), the second is
(0,1),
        and the third (0,2).  The 201st corresponds to (1,0), etc.  The 64001st
        byte is the green component of (0,0).
           Only the low six bits of each byte are used.

        Medium resolution:

           The picture is arranged vertically, instead of horizontally.
        The first word is pixel (0,0), the second is (0,1), and the third
        (0,2).  The 200th is (1,0) etc.
           Each word is divided up into the RGB values for the corresponding
        pixel, as follows:

          Bit:  (MSB) 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 (LSB)
                      -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
                       0 B4 B3 B2 B1 B0 G4 G3 G2 G1 G0 R4 R3 R2 R1 R0

        Bit 15 is not used.

        High resolution:
           
           Image layout not yet known. Appears to be 6-bit grayscale.

These files are created by CE.PRG which comes with the ComputerEyes
hardware. It's not documented in the manual how to create these files.
You must hold down the Alternate key while clicking Save or Load in 
the File drop-down menu.

Further more the program PicSwitch v1.0.1 can process these files. This
feature is also not documented.

Indecently CE.PRG and PicSwith are both written by John Brochu.
