NAME

       pjtoppm - convert an HP PaintJet file to a portable pixmap

SYNOPSIS

       pjtoppm [paintjet]

DESCRIPTION

       Reads an HP PaintJet file as input and converts it into a portable pixmap.  This was a quick hack to save some trees, and it only handles a
       small subset of the paintjet commands.  In particular, it will only handle enough commands to convert most raster image files.

NAME

       ppmtopj - convert a portable pixmap to an HP PaintJet file

SYNOPSIS

       ppmtopj  [-gamma  val]  [-xpos val] [-ypos val] [-back dark|lite] [-rle] [-center] [-render none|snap|bw|dither|diffuse|monodither|monodif-
       fuse|clusterdither|monoclusterdither] [ppmfile]

DESCRIPTION

       Reads a portable pixmap as input and converts it into a format suitable to be printed by an HP PaintJet printer.

       For best results, the input file should be in 8-color RGB form; i.e. it should have only the 8 binary combinations of full-on and  full-off
       primaries.  You could get this by sending the input file through ppmquant -map with a map file such as:
           P3
           8 1
           255
           0 0 0      255 0 0    0 255 0    0 0 255
           255 255 0  255 0 255  0 255 255  255 255 255
       Or else you could use use ppmdither -red 2 -green 2 -blue 2.

OPTIONS

       -rle          Run length encode the image.  (This can result in larger images)

       -back         Enhance the foreground by indicating if the background is light or dark compated to the foreground.

       -render alg   Use an internal rendering algorithm (default dither).

       -gamma int    Gamma correct the image using the integet parameter as a gamma (default 0).

       -center       Center the image to an 8.5 by 11 page

       -xpos pos     Move by pos pixels in the x direction.

       -ypos pos     Move by pos pixels in the y direction.

BUGS

       Most of the options have not been tested because of the price of the paper.
