RLECCUBE(1) 1 (January 30, 1991) 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 outfile is "-", or if it is not specified, the
output will be written 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.
