Early versions of Paintworks were called N-Vision. These are often mistaken as
NEOchrome files. One should not rely on the file extension to determine the contents.

1 word file id [0x00]
recommend using 'secondary file id' for identification
1 word resolution [0 = low, 1 = medium, 2 = high]
recommend using 'flags' to determine resolution
16 words palette
12 bytes file name, usually [" . "]
1 word ?
1 word ?
1 word ?
9 bytes secondary file id ["ANvisionA"]
1 byte flags, bit field: cxrrtttt
c = compression flag [1 = compressed]
x = not used
r = resolution [0 = low, 1 = medium, 2 = high]
t = type [0 = page, 1 = screen, 2 = clipart, 4 = pattern]
page = double high, thus 320x400, 640x400, 640x800
screen = standard st resolutions
clipart = standard st resolutions
pattern = no documentation at this time
64 bytes ?
---------
128 bytes total for header

Uncompressed images are simply screen dumps as one might expect.

Compressed images are currently undocumented.
