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

== Format ==
"Old format" files have a 6-byte header, and "modern format" files have an 8-byte header.

== Identifiers ==
The MGR software does not appear to use any filename extension for this format, but some third-party software uses '''.mgr'''.

== Identification ==
Files begin with a two-byte ASCII signature:
{| class="wikitable"
! 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"?
