RLECCUBE(1)RLECCUBE(1)NAME
rleccube - Make a picture of a color cube.
SYNOPSIS
rleccube [ -w squares-wide ] [ -o outfile ] [ cube-side ]
DESCRIPTION
This program computes an RLE(5) image of slices through the RGB color
cube. The arguments control the size of the cube and the arrangement
of the slices into an image. Slices are taken in planes of constant
red, with green varying along the "x" axis and blue along the "y" axis
within a slice. The slice for red=0 is placed in the lower left corner
of the image; red increases along the bottom row, then to the left of
the next row, and so on. The rleswap(1) program can be used to get an
image with slices of constant green or blue.
OPTIONS-w squares-wide
The number of slices in a row will be squares-wide. The default
is the smallest divisor of cube-side larger than sqrt(cube-
side). If squares-wide is not an exact divisor of cube-side,
the top row will be filled in with slices starting from red near
0.
-o outfile
If specified, the output will be written to this file. If out‐
file is "-", or if it is not specified, the output will be writ‐
ten to the standard output stream.
cube-side
The number of samples on each side of the cube. Each slice will
be cube-sidexcube-side, and there will be cube-side slices. The
default value is 64.

BUGS
It really should fill in the excess space in the last row with black.
