SYNOPSIS

rlecat [ -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 comment 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 outfile is "-", or if it is not specified, the output will be written 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 identified 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 correctly.
