Lotus 1-2-3 Chart, or Lotus PIC, is a vector graphics format associated with Lotus 1-2-3 and associated program PrintGraph. Based on Lotus Picture Description Language.
[edit] Identification
Known Lotus PIC files begin with 16 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. The last four bytes may equal the width and height minus one.
[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.]
All PIC files start with the 16 byte header and end with opcode 6nh, this terminates the interpretation of the PDL instructions. The variable n represents the lower order four bits of the opcode byte, and can be any value.
PIC files can be device specific on how they are interpreted.
