MDI is a proprietary image format used by Microsoft Office Document Imaging.
It is almost identical to TIFF, but has a different header, and may use one of several undocumented compression schemes.
Identification
Files begin with bytes 45 50 2a 00.
Compression
The compression schemes are reportedly known by the following names:
| Code | Compression scheme |
|---|---|
| 34718 | MODI_BLC |
| 34719 | MODI_VECTOR |
| 34720 | MODI_PTC |
Another source swaps the definitions of 34719 and 34720:
| Code | Compression scheme |
|---|---|
| 34718 | Binary Level Codec |
| 34719 | Progressive Transform Codec |
| 34720 | Vector |
