PIXIT (if that is its name) is a DOS toolkit for making an executable file that, when executed, displays an image.
It was developed by an anonymous person. The name "PIXIT" is derived from the distribution filename; no name is used by the software or its nonexistent documentation.
The generation process starts with a GIF file, which is converted to a non-compressed format.
The COM format starts with the bytes in the included PIX320.COM file. The first 16 are
bc 00 01 b8 13 00 cd 10 b8 12 10 bb 00 00 b9 00.
The EXE format starts with the bytes in the included PIX640.EXX file.
