NEOchrome

NEOchrome format is a raster image file format associated with the NEOchrome graphics editor for Atari ST.

See also NEOchrome Master.

Format details
NEOchrome files have a 128-byte header, followed by 32000 bytes of uncompressed image data, for a total file size of 32128 bytes.

NEOchrome images are 320×200 pixels, with 16 colors.

The format may seem to allow for other video modes, and other image dimensions. However, such files are generally not supported, and are probably not valid.
