Naïve Image Formats

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. The next byte is:
 * ('E') for NIE
 * ('I') for NII
 * ('A') for NIA
