PIC2FIG(LOCAL)PIC2FIG(LOCAL)NAMEpic2fig - Fig preprocessor for drawing simple pictures
SYNOPSISpic2fig file
DESCRIPTION
Pic2fig is a Fig(l) preprocessor for drawing simple figures in Fig
code. The basic objects are box, line, arrow, circle, ellipse, arc and
text.
When pic2fig is executed, it produces an output file in the current
directory. The name is constructed from the input file's name. If the
input filename ends with .pic, then that extension will be replaced by
.fig. Otherwise, .fig is appended to the input filename. If file does
not exist, then pic2fig tries appending .pic to the name.
The input language for pic2fig is identical to that for pic, which is
used with dtroff(l), except for extensions listed below. Things
enclosed within .PS and .PE will be translated by pic2fig to Fig inter‐
mediate code which can be further translated into a number of graphics
description languages. Text not within .PS and .PE will be passed
unaltered to the output file. The default line thickness of drawings
is 8 milli-inches. You may adjust this using the command:
.ps n
for n milli-inches. This command must be given in the first column.
Changing the drawing thickness applies to solid, dashed, and dotted
lines, as well as circles, arcs, and ellipses.
Setting the font for text may be done using a
.ft n
command, where n corresponds to the following PostScript fonts:
-1 Default font
0 Times Roman
1 Times Italic
2 Times Bold
3 Times Bold Italic
4 AvantGarde Book
5 AvantGarde Book Oblique
6 AvantGarde Demi
7 AvantGarde Demi Oblique
8 Bookman Light
9 Bookman Light Italic
10 Bookman Demi
11 Bookman Demi Italic
12 Courier
13 Courier Oblique
14 Courier Bold
15 Courier Bold Oblique
16 Helvetica

22 Helvetica Narrow Bold
23 Helvetica Narrow Bold Oblique
24 New Century Schoolbook Roman
25 New Century Schoolbook Italic
26 New Century Schoolbook Bold
27 New Century Schoolbook Bold Italic
28 Palatino Roman
29 Palatino Italic
30 Palatino Bold
31 Palatino Bold Italic
32 Symbol
33 Zapf Chancery Medium Italic
34 Zapf Dingbats
Normally, the distance between text is 12 points. If you're using
larger text to label objects, this should be set to an appropriate
larger value. This can be done using the
.baseline n
command, where n is any real value, whose units are in typesetter
points.
The shading texture may be controlled with the command:
.tx N w1 w2 ... wN
where the wN are 32-bit integers expressed in hexadecimal. This com‐
mand must be given in the first column.
Other input lines which begin with a period character are passed
through to the output unaltered except for stripping the initial period
character. It is recommended that you not use this feature unless you
really know what you're doing.
Extensions and differences: Text in pic2fig can be any arbitrary TeX
text. It is set in restricted horizontal mode.
Boxes, circles, and ellipses may have two attributes not available in
pic: they may be ``shaded'' or ``white''. Because of restrictions in
the current Imagen postprocessor, objects may not be given other
attributes (eg, ``dashed'' or ``invis'') if they are ``shaded'' or
``white'' for that output device. Shaded figures are grayed in their
interior. White objects force their interior to be whitened if it was
shaded by another object. Objects are ``stacked'' on each other in the
order in which they are defined in the pic2fig input file. The shading
attributes are subject to restrictions of the capabilities of the out‐
put device used.
