15 picttoppm - convert a Macintosh PICT file into a portable pixmap
16 !!SYNOPSIS
17
18
19 __picttoppm__ [[__-verbose__] [[__-fullres__]
20 [[__-noheader__] [[__-quickdraw__]
21 [[__-fontdir__file__]__ [[''pictfile'']
22 !!DESCRIPTION
23
24
25 Reads a PICT file (version 1 or 2) and outputs a portable
26 pixmap. Useful as the first step in converting a scanned
27 image to something that can be displayed on
28 Unix.
29 !!OPTIONS
30
31
32 __-fontdir__ ''file''
33
34
35 Make the list of BDF fonts in ``file'' available for use by
36 ''picttoppm'' when drawing text. See below for the format
37 of the fontdir file.
38
39
40 __-fullres__
41
42
43 Force any images in the PICT file to be output with at least
44 their full resolution. A PICT file may indicate that a
45 contained image is to be scaled down before output. This
46 option forces images to retain their sizes and prevent
47 information loss. Use of this option disables all PICT
48 operations except images.
49
50
51 __-noheader__
52
53
54 Do not skip the 512 byte header that is present on all PICT
55 files. This is useful when you have PICT data that was not
56 stored in the data fork of a PICT file.
57
58
59 __-quickdraw__
60
61
62 Execute only pure quickdraw operations. In particular, turn
2 perry 63 off the interpretation of special !PostScript printer
1 perry 64 operations.
65
66
67 __-verbose__
68
69
70 Turns on verbose mode which prints a a whole bunch of
71 information that only ''picttoppm'' hackers really care
72 about.
73 !!BUGS
74
75
76 The PICT file format is a general drawing format.
77 ''picttoppm'' does not support all the drawing commands,
78 but it does have full support for any image commands and
79 reasonable support for line, rectangle, polgon and text
80 drawing. It is useful for converting scanned images and some
81 drawing conversion.
82
83
84 Memory is used very liberally with at least 6 bytes needed
85 for every pixel. Large bitmap PICT files will likely run
86 your computer out of memory.
87 !!FONT DIR FILE FORMAT
88
89
90 ''picttoppm'' has a built in default font and your local
91 installer probably provided adequate extra fonts. You can
92 point ''picttoppm'' at more fonts which you specify in a
93 font directory file. Each line in the file is either a
94 comment line which must begin with ``#'' or font
95 information. The font information consists of 4 whitespace
96 spearated fields. The first is the font number, the second
97 is the font size in pixels, the third is the font style and
98 the fourth is the name of a BDF file containing the font.
99 The BDF format is defined by the X window system and is not
100 described here.
101
102
103 The font number indicates the type face. Here is a list of
104 known font numbers and their faces.
105
106
107 0 Chicago
108 1 application font
109 2 New York
110 3 Geneva
111 4 Monaco
112 5 Venice
113 6 London
114 7 Athens
115 8 San Franciso
116 9 Toronto
117 11 Cairo
118 12 Los Angeles
119 20 Times Roman
120 21 Helvetica
121 22 Courier
122 23 Symbol
123 24 Taliesin
124 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:
125
126
127 1 Boldface
128 2 Italic
129 4 Underlined
130 8 Outlined
131 16 Shadow
132 32 Condensed
133 64 Extended
134 Obviously the font defintions are strongly related to the Macintosh. More font numbers and information about fonts can be found in Macintosh documentation.
