NAME

       ppmtolj - convert a portable pixmap to an HP LaserJet PCL 5 Color file

SYNOPSIS

       ppmtolj [-gamma val] [-resolution 75|100|150|300|600] [-delta] [-float] [-noreset] [ppmfile]

DESCRIPTION

       Reads a portable pixmap as input and converts it into a color file suitable to be printed by an HP color PCL 5 printer.

OPTIONS

       -delta	     Apply delta row compression to reduce the size of the pcl file.

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

       -float	     Suppresses positioning information. The default is to write the sequence ESC&l0E to the output.

       -noreset      Prevents writing of the reset sequence to the begining and end of the output.

       -resolution   Set the required output resolution 75|100|150|300|600

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.
