This utility encodes an image as a Gameduino character map. A summary of what is valid:

• width and height must be multiple of 8
• each 8x8 character can use at most 4 colors (although this utility will palettize each 8x8 cell if necessary)
• no more than 256 unique characters.

See Gameduino for Artists for more details
