PCX-to-Executable (long name: Birken Software's PCX-TO-EXECUTABLE Converter; short name: PCX2EXE) is a DOS utility that converts a PCX image file to an EXE file that, when executed, displays the image. It was developed Birken Software.

Only 256-color 320x200 images are supported.

Discussion

PCX-to-Executable v1.00 (unregistered) has an issue that causes it to reject many PCX files that should be compatible with it: It requires the "resolution" field to be exactly 320x200. That is, the bytes at offset 12 need to be 40 01 c8 00. This is an unimportant and poorly-documented field that it ought to ignore.

Format details

A file made by v1.00 (unregistered) appears to consist of a 17891-byte executable module that is always the same, then a copy of the original PCX file, and ending with 4 bytes giving the size of the PCX file.

Identification

Undetermined. The generated files don't appear to have any deliberate signatures. A known version could easily be identified; see the "Format details" section above.
