FRM16

There are at least two types - 64 and 68

Type 64 seems to be a trivial unencoded bitmap with some indices in the end. They are used e.g. for area minimaps.

Type 68 is some encoded format - RLE and possibly some JPEG compression [FIXME: add quote]

Format as deduced by Miloch:

Header (28 bytes) Offset Size Description 0x00 2 Signature (1032) 0x06 2 Width in pixels (portraits = 90, areas = 779) 0x08 2 Height in pixels (portraits = 111, areas = 330) 0x0a 2 Unknown (variably 0, 1182, 1565, 2624, 3711, etc.) 0x0c 2 Unknown (64 or 68) 0x10 4 Data size (areas = 515496-514140 = 1356/54C) 0x24 4 Data size (redundant) 0x28 x Image data (where x = Data size) y z Index data? (where y = file size - (data size + 28)
