MGR bitmap is an image file format associated with the ManaGeR (or MGR) windowing system.
Contents |
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:
| 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"? |
