NAME
ppmtosixel - convert a portable pixmap into DEC sixel formatSYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC LJ250 color inkjet printer.If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS
- -raw
- If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to compressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magnitude larger than a compressed file and prints much slower.
- -margin
- If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is specified, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.SEE ALSO
