.RPGM File

The rpgm file extension is used for portable greyscale image format. BMPlus files are created by Jef Poskanzer's PBMPlus Portable bitmap utilities.

The portable graymap format is a lowest common denominator grayscale file format.

This rpgm file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
