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
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.
