Naïve Image Formats
From Just Solve the File Format Problem
The Naïve Image Formats are a set of simple uncompressed raster image and animation file formats. They are loosely associated with Google's Wuffs programming language. As of 2019-12, the specifications are a work in progress.
The formats are potentially usable as intermediate or "neutral" formats, similar to the Netpbm formats or farbfeld.
There are three formats:
- NIE - Still image
- NII - Animated image, out-of-band frames
- NIA - Animated image, in-band frames

Identification
All formats begin with bytes 6e c3 af. The next byte is:
-
0x45('E') for NIE -
0x49('I') for NII -
0x41('A') for NIA
