picttoppm !!!picttoppm NAME SYNOPSIS DESCRIPTION OPTIONS BUGS FONT DIR FILE FORMAT SEE ALSO AUTHOR ---- !!NAME picttoppm - convert a Macintosh PICT file into a portable pixmap !!SYNOPSIS __picttoppm__ [[__-verbose__] [[__-fullres__] [[__-noheader__] [[__-quickdraw__] [[__-fontdir__file__]__ [[''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. !!SEE ALSO Inside Macintosh volumes 1 and 5, ppmtopict(1), ppm(5) !!AUTHOR Copyright 1993 George Phillips ----
