Format
The first byte of the file is a code indicating the image type. Palette color animation is optionally supported.
| Code | Dimensions | Colors | Animated | Filename extensions |
|---|---|---|---|---|
| 0 | 320×200 | 16 | No | .TNY, .TN1 |
| 1 | 640×200 | 4 | No | .TNY, .TN2 |
| 2 | 640×400 | 2 | No | .TNY, .TN3 |
| 3 | 320×200 | 16 | Yes | .TNY, .TN1, unofficially .TN4 |
| 4 | 640×200 | 4 | Yes | .TNY, .TN2, maybe .TN5 |
| 5 | 640×400 | 2 | Yes | .TNY, .TN3, maybe .TN6 |
Files consist of a 37-byte (if not animated) or 41-byte (if animated) header, followed by a "control" segment and a "data" segment which together form the compressed image data.
