NAME
picttoppm - convert a Macintosh PICT file into a portable
pixmap
SYNOPSIS
picttoppm [-verbose] [-fullres] [-noheader] [-quickdraw] [-
fontdirfile] [pictfile]
DESCRIPTION
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.
OPTIONS
-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.
-fullres
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.
-noheader
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.
-quickdraw
Execute only pure quickdraw operations. In particular,
turn off the interpretation of special PostScript
printer operations.
-verbose
Turns on verbose mode which prints a a whole bunch of
information that only picttoppm hackers really care
about.
BUGS
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 support
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.

FONT DIR FILE FORMAT
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 faces.
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.
