Overview

MGR bitmap is an image file format associated with the ManaGeR (or MGR) windowing system.

Identification

Apparently, MGR bitmap files do not conventionally have a filename extension.

Files begin with a two-byte ASCII signature:

Signature Format
"yz" modern format, 8-bit aligned
"yx" modern format, squeezed
"xz" old format, 1-bit, 32-bit aligned
"zz" old format, 1-bit, 16-bit aligned
"zy" old format, 8-bit, 16-bit aligned
"xy" same as "zy"?
