RLECAT(1)RLECAT(1)NAMErlecat - concatenate and repeat images.
SYNOPSISrlecat [ -c ] [ -n repeat-count ] [ -o outfile ] [ files ... ]
DESCRIPTION
This program will concatenate all the input RLE(5) images, adding
titles, and optionally repeating the images a specified number of
times. For each input file, it copies all images to the output file.
If an image does not have a title or TITLE comment, and the input is
not coming from the standard input, then the file name (and an image
number, if it is not the first image in the file) is added as a TITLE
comment. If the input file were named 'images.rle', the first image
would be given a comment TITLE=images.rle, the second would get a com‐
ment TITLE=images.rle(2), and so on.
OPTIONS-c With -n, specifies that the output images should be "collated".
In other words, the repeat sequence will be 1 2 3 ... 1 2 3 ...
instead of the default of 1 1 ... 2 2 ... 3 3 ...
-n repeat-count
Specifies that each input image should be repeated repeat-count
times. The "repeat unit" (if -c is specified, this is the
entire concatenated sequence of input images, otherwise it is
just each image, separately) is written to a temporary file, and
then copied to the output the requisite number of times.
-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.
files The input will be read from these files. If a file name is "-",
or none are specified, the input will be read from the standard
input stream.
EXAMPLES
rlebg 128 128 128 | rlecat-n 25
Generates 25 copies of a gray background; useful for using
rlecomp(1) to put background on an animation sequence (with 25
or fewer frames).
rlecat *.rle | <some processing> | getx11
Adds TITLE comments so the individual images are correctly iden‐
tified by getx11(1).
rlecat-c -r 3 anim*.rle
Generates an animation with 3 repeats of the action.
rlecat-r 3 anim*.rle
Generates a "triple-framed" animation - each frame is repeated 3
times.

BUGS
If the /tmp directory is not writable, or if there is not sufficient
space on /tmp to hold a repeat unit, the program will not work cor‐
rectly.
