NAME
ppmtolss16 -- Convert a PPM to an LSS16 image
SYNOPSIS
ppmtolss16 [ #rrggbb=i ...] [< input.ppm] [> output.rle]
DESCRIPTION
This manual page documents briefly the ppmtolss16 command. The ppmtolss16 program converts a "raw" PPM file with max 16 colors to a simple RLE-based format: simple RLE-based format unint32 0x1413f3d magic (littleendian) unint16 xsize littleendian unint15 ysize littleendian 16 x unint8 r,g,b color map Color map is in 6-bit format (each byte is 0..63) Then, a sequence of nybbles: N ... if N is != previous pixel, one pixel of color N, otherwise run sequence follows ... M ... if M > 0 then run length is M+1, otherwise run sequence is encoded in two nybbles, littleendian, +17 The nybble sequences are on a per-row basis, runs may not extend across rows and odd-nybble rows are zero-padded. At the start of a row, the "previous pixel" is assumed to be zero.
OPTIONS
A summary of options is included below. #rrggbb=i Specify that the color #rrggbb (hex) should be assigned index i (decimal).
BUG
This program cannot handle comments in the header, nor "plain" ppm format.
