NAME
rlezoom - Magnify an RLE file by pixel replication.SYNOPSIS
rlezoom factor [ y-factor ] [ -f ] [ -o outfile ] [ infile ]DESCRIPTION
This program magnifies (zooms) an RLE(5) file by a floating point factor. 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 magnified 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 specified.You should use rlezoom over fant(1) if you just want a quick magnification of an image with the pixel boundaries showing. It is significantly faster than fant because it does no arithmetic on the pixel values. 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 current directory, you should prefix it with "./" so that it will not be confused with factor or y-factor.
