6e 69 66
1 byte width then 1 byte height, the width/height is equal the the value of the byte plus one.
The following n bytes, n being defined as width*height, are pixels referring to the palette.
Then the palette is the rest of the file.
| byte | meaning | comment |
|---|---|---|
| 0-2 | File identifier | always 6e 69 66 |
| 3 | Width | width = value + 1 |
| 4 | Height | height = value +1 |
| 5-? | Pixels | Each bytes refers to a palette value. e.g. the first color in the palette is value 0. |
| ?-end | Palette | The length of this palette has to be a multiple of 3 because one color is 3 bytes. e. g. every 3 bytes is one color. |
