Lotus 1-2-3 Chart, or Lotus PIC, is a vector graphics format associated with Lotus 1-2-3.

Identification

Known Lotus PIC files begin with bytes 01 00 00 00 01 00 08 00 44 00 00 00 00 0c 7f 09 06. The significance of these byte values is not known, and other values might be possible.

[Ed. note: The Encyclopedia of Graphics File Formats appears to have an error: It says there are three 0x00 bytes after the 0x44 byte, when there probably should be four.]
