       picttoppm - convert a Macintosh PICT file into a portable pixmap

       picttoppm [-verbose] [-fullres] [-noheader] [-quickdraw] [-fontdirfile] [pictfile]

       Reads  a  PICT  file  (version 1 or 2) and outputs a portable pixmap.  Useful as the first
       step in converting a scanned image to something that can be displayed on Unix.

       -fontdir file
	      Make the list of BDF fonts in ``file'' available for use by picttoppm when  drawing
	      text.  See below for the format of the fontdir file.

	      Force any images in the PICT file to be output with at least their full resolution.
	      A PICT file may indicate that a contained image is to be scaled down before output.
	      This  option forces images to retain their sizes and prevent information loss.  Use
	      of this option disables all PICT operations except images.

	      Do not skip the 512 byte header that is present on all PICT files.  This is  useful
	      when you have PICT data that was not stored in the data fork of a PICT file.

	      Execute only pure quickdraw operations.  In particular, turn off the interpretation
	      of special PostScript printer operations.

	      Turns on verbose mode which prints a a whole bunch of information that  only  pict-
	      toppm hackers really care about.

       The  PICT  file	format	is  a general drawing format.  picttoppm does not support all the
       drawing commands, but it does have full support for any image commands and reasonable sup-
       port  for  line,  rectangle, polgon and text drawing.  It is useful for converting scanned
       images and some drawing conversion.

       Memory is used very liberally with at least 6 bytes needed for every pixel.  Large  bitmap
       PICT files will likely run your computer out of memory.

       picttoppm  has a built in default font and your local installer probably provided adequate
       extra fonts.  You can point picttoppm at more fonts which you specify in a font	directory
       file.   Each line in the file is either a comment line which must begin with ``#'' or font
       information.  The font information consists of 4 whitespace spearated fields.   The  first
       is the font number, the second is the font size in pixels, the third is the font style and
       the fourth is the name of a BDF file containing the font.  The BDF format  is  defined  by
       the X window system and is not described here.

       The  font  number indicates the type face.  Here is a list of known font numbers and their

       0    Chicago
       1    application font
       2    New York
       3    Geneva
       4    Monaco
       5    Venice
       6    London
       7    Athens
       8    San Franciso
       9    Toronto
       11   Cairo
       12   Los Angeles
       20   Times Roman
       21   Helvetica
       22   Courier
       23   Symbol
       24   Taliesin

       The font style indicates a variation on the font.  Multiple variations may apply to a font
       and the font style is the sum of the variation numbers which are:

       1    Boldface
       2    Italic
       4    Underlined
       8    Outlined
       16   Shadow
       32   Condensed
       64   Extended

       Obviously  the  font  defintions are strongly related to the Macintosh.	More font numbers
       and information about fonts can be found in Macintosh documentation.
