RLEHDR(1)RLEHDR(1)NAMErlehdr - Prints the header of an RLE file
SYNOPSISrlehdr [ -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 chan‐
nels 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-sepa‐
rated 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 tool‐
kit version and patch level. No input files will be processed
if this option is given.
EXAMPLESrlehdr image.rle
