NAME

       pnmtosgi - convert a portable anymap to a SGI image file

SYNOPSIS

       pnmtosgi [-verbatim|-rle] [-imagename Name] [pnmfile]

DESCRIPTION

       Reads  a  portable  anymap as input. Produces an SGI image file as output.  The SGI image will be 2-dimensional (1 channel) for PBM and PGM
       input, and 3-dimensional (3 channels) for PPM.

OPTIONS

       -verbatim
              Write an uncompressed file.

       -rle (default)
              Write a compressed (run length encoded) file.

       -imagename name
              Write the string "name" into the imagename field of the header.  The name string is limited to 79 characters.  If no name is  given,
              pnmtosgi writes "no name" into this field.

BUGS

       Probably.

NAME

       ppmtopcx - convert a portable pixmap into a PCX file

SYNOPSIS

       ppmtopcx [-24bit] [-packed] [-xpos=cols] [-ypos=rows] [ppmfile]

DESCRIPTION

       Reads a PPM image as input.  Produces a PCX file as output.  The type of the PCX file depends on the number of colors in the pixmap:

       16 colors or less:
	      1 bit/pixel, 1-4 planes.

       256 colors or less:
	      8 bits/pixel, 1 plane, colormap at the end of the file.

       More than 256 colors:
	      24bit truecolor file (8 bits/pixel, 3 planes).

OPTIONS

       -24bit Produce a 24bit truecolor file, even if the pixmap has 256 colors or less.

       -packed
	      Use "packed pixel" format for files with 16 colors or less: 1, 2, or 4 bits/pixel, 1 plane.

       -xpos=cols

       -ypos=rows
	      These options set the position of the image in some field (e.g. on a screen) in columns to the right of the left edge and rows below
	      the top edge.  The PCX format contains image position information.  Don't confuse this with the position	of  an	area  of  interest
	      within  the  image.   For example, using pnmpad to add a 10 pixel left border to an image and then converting that image to PCX with
	      xpos = 0 is not the same as converting the original image to PCX and setting xpos = 10.

	      The values may be from -32767 to 32768.

	      The default for each is zero.
