.SH DESCRIPTION
|
|
|
9 |
.I Laserbar
|
|
|
10 |
prints on the standard output the PostScript text that will produce
|
|
|
11 |
(on a suitable laser printer) the \s-2CODE-39\s+2 bar code
|
|
|
12 |
corresponding to
|
|
|
13 |
.I string.
|
|
|
14 |
The \fBr\fP option may be used to specify a rotation (in
|
|
|
15 |
degrees) of the bar code.
|
|
|
16 |
The \fBx\fP, \fBy\fP, \fBX\fP, and \fBY\fP options may be used to specify
|
|
|
17 |
an x- or y-axis offset (in inches) or scaling factor, respectively.
|
|
|
18 |
(The offset is measured from the lower left corner of the page
|
|
|
19 |
to the upper left corner of the bar
|
|
|
20 |
code. By default, the bar code produced is one inch high, and is scaled
|
|
|
21 |
so that the narrowest elements are each 1/72-inch \- i.e., one point \- wide.)
|
|
|
22 |
If the \fBl\fP option is specified, the bar code produced is labeled.
|
|
|
23 |
If the \fBn\fP option is specified, the resulting PostScript text
|
|
|
24 |
includes a leading \f(CWnewpath\fP command, so that the text may stand
|
|
|
25 |
alone or precede any other PostScript commands.
|
|
|
26 |
If the \fBs\fP option is specified, the resulting PostScript text includes
|
|
|
27 |
a trailing \f(CWshowpage\fP command, so that the text may stand alone
|
|
|
28 |
or follow any other PostScript commands.
