NAME

       calibrate_ppa - pnm2ppa calibration tool

SYNOPSIS

       calibrate_ppa [options]

DESCRIPTION

       Produces various PixMap (PPM) files used for calibrating pnm2ppa.

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

NOTE

       The size of a  full-page PixMap is 100MB!!.  These PixMaps should be piped directly to pnm2ppa, except in the case of the  -g option, where
       the PixMap should be viewed or printed by other means.

OPTIONS

       -g, --gamma
	      produce  gamma.ppm (10MB, used in color calibration).

       -h, --help
	      displays this help text.

       -o <outfile>
	      output to file <outfile>, "-o -" means stdout (default)

       -p <n> create test pattern number <n>

       --align
	      pattern 0:  align print heads. (default)

       --test pattern 1:  test alignment.

       --clean
	      pattern 2:  clean print head.

       --center
	      pattern 3:  center paper.

       -s <paper>
	      default papersize (a4, legal, letter = us (default))

NAME

       pbmpage - create a one page test pattern for printing

SYNOPSIS

       pbmpage [-a4] test_pattern

DESCRIPTION

       pbmpage	generates a one page test pattern to print on a sheet of paper, for use in calibrating a printer.  The test pattern in is PBM for-
       mat.

       pbmpage produces an image intended for 600 dots per inch printer resolution.

       If you are printing on an HP PPA printer, you can convert the output of this program to a stream that you can feed to the printer with pbm-
       toppa.

       Bear  in  mind  that  when you print the test pattern, you are testing not only the printer, but any converter or driver software along the
       printing path.  Any one of these components may adjust margins, crop the image, erase edges, and such.

       If, due to addition of margins, the printer refuses to print the image because it is too big, use pnmcut to cut the right and bottom  edges
       off the test pattern until it is small enough to print.

       test_pattern is the number of the test pattern to generate, as follows.	The default is 1.

       1      A grid ruled in numbers of pixels.  The outermost rules are exactly at the edges of the paper.

       2      A vertical line segment, one pixel wide, extending 1/2" up from the exact center of the page.

       3      Two  diagonal line segments, one starting at the upper left corner of the page, the other starting from the lower left corner of the
	      page.  Both extend 1/2" toward the center of the page at 45 degrees.

OPTIONS

       -a4    Generate an image for A4 (European) paper.  Without this option, pbmpage generates an image for US standard paper (8 1/2" wide x 11"
	      high).
