picttoppm - convert a Macintosh PICT file into a portable pixmap
picttoppm [-verbose] [-fullres] [-noheader] [-quickdraw] [-fontdirfile]
Reads a PICT file (version 1 or 2) and outputs a portable pixmap. Use-
ful as the first step in converting a scanned image to something that
can be displayed on Unix.
Make the list of BDF fonts in ``file'' available for use by
picttoppm when drawing text. See below for the format of the
Force any images in the PICT file to be output with at least
their full resolution. A PICT file may indicate that a con-
tained 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
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 informa-
tion that only picttoppm 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 support for line, rectangle, polgon and
text drawing. It is useful for converting scanned images and some
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
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 con-
taining 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.
1 application font
2 New York
8 San Franciso
12 Los Angeles
20 Times Roman
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 num-
bers which are:
Obviously the font defintions are strongly related to the Macintosh.
