SYNOPSIS

rlehdr [ -b ] [ -ccomment-names ] [ -d ] [ -m ] [ -v ] [ files ... ]

DESCRIPTION

This program prints the header of RLE(5) files in a human readable form. If the optional files argument is not supplied, input is read from standard input.

OPTIONS

-b Print the information in a "brief" one-line form. The form of the output line is
name: [l,b]+[xs,ys]xnc+A, BG=color, map=NxL, (C)
Where [l,b] is the position of the lower-left corner of the image, [xs,ys] is the size of the image in pixels, nc is the number of channels saved, +A is present if an alpha channel is saved. BG= or OV= indicate that a background color was saved; OV= means that the existing background is not cleared to the background color before the image is read (this was used for a cheap form of compositing, but is basically obsolete now). color is the saved background color. The map= entry will be present only if a color map was saved; N is the number of channels in the color map and L is the length of the map. Finally (C) is appended if there are comments present.
-c comment-names
  If a comment identified by any of the words in the comma-separated list comment-names is present in the input file, its first line will be printed. Each name is tried, in turn, and only the first match is printed. If no match is found, but comments are present, (C) will be printed. The -c flag implies -b.
-d Dump a very verbose version of the image contents as text to the standard error output stream.
-m Print out the color map information. -v Prints the raster toolkit version and patch level. No input files will be processed if this option is given.

EXAMPLES

rlehdr image.rle
  Print the header information for all images in the file image.rle.
rlehdr -m image.rle
  Also print the color map contents, if one is present.
rlehdr -b *.rle
  Print one line summaries of all the images in the directory.
rlehdr -c title,TITLE *.rle
  Print one line summaries of all the images, and print the title of any that have a title comment.
