TI picture file is a family of bi-level raster image formats used with Texas Instruments calculators. A picture file is a kind of TI variable file that contains a variable of type "picture".

There is a version of the format for each model of TI calculator. About three or four of the versions are meaningfully different.

Identification

All TI files begin with an 8 byte ASCII signature that starts with "**TI" and indicates the version or model, for example "**TI92**" or "**TI83F*".

Picture files use a filename extension that ends with the letter "i".

There are also "group" files, whose extension ends with "g". A group file contains multiple variables, one or more of which may be images.
