NAME

rastrepl − magnify a raster image by 2 times

SYNOPSIS

rastrepl [ input-file [ output-file ]]

DESCRIPTION

Rastrepl reads input-file (or the standard input if input-file is not specified) which should be in rasterfile format (see /usr/include/rasterfile.h), replicates each pixel in both the x and y directions, and writes the resulting rasterfile to output-file (or the standard output if output-file is not specified). 

EXAMPLES

tutorial% screendump  |  rastrepl  |  lpr −Pversatec −v

sends a rasterfile containing the current frame buffer to the Versatec plotter, doubling the size of the image so that it fills a single page.
