RLEHDR(1) 1 (Jan 22, 1987) RLEHDR(1)
NAME
rlehdr - Prints the header of an RLE file
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
