RLEZOOM(1)RLEZOOM(1)NAMErlezoom - Magnify an RLE file by pixel replication.
SYNOPSISrlezoom factor [ y-factor ] [ -f ] [ -o outfile ] [ infile ]
DESCRIPTION
This program magnifies (zooms) an RLE(5) file by a floating point fac‐
tor. Each pixel in the original image becomes a block of pixels in the
output image. If no y-factor is specified, then the image will be mag‐
nified by factor equally in both directions. If y-factor is given,
then each input pixel becomes a block of factor × y-factor pixels in
the output. If factor or y-factor is less than 1.0, pixels will be
dropped from the image. There is no pixel blending performed. Input
is taken from infile, or from the standard input if not specified. The
magnified image is written to the standard output, or outfile, if spec‐
ified.
You should use rlezoom over fant(1) if you just want a quick magnifica‐
tion of an image with the pixel boundaries showing. It is signifi‐
cantly faster than fant because it does no arithmetic on the pixel val‐
ues. If you need blending between pixels in the magnified image, then
fant is the correct program to use. Use rlezoom-f factor y-factor to
produce an image the same size as fant -p 0 0 -s factor y-factor for
previewing purposes.
Note: due to the way that scanargs(3) parses the arguments from the
command line, if the name of infile is a number, and it is in the cur‐
rent directory, you should prefix it with "./" so that it will not be
confused with factor or y-factor.
