HP2XX, A HP-GL Converter
1.2 hp2xx for the impatient
This section is intended to give those of you a quick-start who are
quite familiar with traditional UNIX-style programs and with HP-GL and
other graphics formats.
The following examples will give you a good idea of hp2xx's
functionality. See section B. Option summary, the Option Summary, for further details.
Preview of HP-GL graphics in file `foo.hp'. The picture will
fit into a square of 200 mm width, assuming that your output device
(screen) features 75 DPI resolution (default).
| | hp2xx -q -d86 -h160 -w220 foo.hp bar.hp
|
Multiple-file preview. Option `-q' puts hp2xx into "quiet" mode.
The picture will fit into a rectangle of 220 mm width and 160 mm height,
assuming a 86 DPI resolution of the output device (screen).
| | hp2xx -t -c12340567 -p12230412 foo.hp
|
Preview, size according to original HP-GL data (as on a plotter),
with different pen colors and sizes. Color and width according to:
| | Pen # : Color code / Size (pixel)
-------------------------------------
1 : 1 (black) / 1
2 : 2 (red) / 2
3 : 3 (green) / 2
4 : 4 (blue) / 3
5 : 0 (background) / 0
6 : 5 (cyan) / 4
7 : 6 (magenta) / 1
8 : 7 (yellow) / 2
|
| | hp2xx -m eps -l a.log -h100 -w150 -p542 foo.hp bar.hp
|
Encapsulated Postscript mode. Files `foo.eps' and `bar.eps'
will be created. The diagnostic output will be written into `a.log',
so hp2xx works quietly. Both EPS pictures will fit into a
rectangle of size 150 x 200 mm. The size (width) of
pen 1: 0.5 mm, pen 2: 0.4 mm, pen 3: 0.2 mm, pen 4 ... pen 8: 0.1 mm.
| | unix% cat foo.hp | hp2xx -m pcl -o30 -O50 -i -F -f- | lpr -P ljet
|
In this generic UNIX example, hp2xx reads HP-GL code from stdin,
converts it to HP-PCL which is suitable for direct output on any HP Laserjet
printer, and pipes the output via stdout into the appropriate printer queue.
Option `-f-' forces hp2xx to write to stdout instead of
a file, `-i' initializes the printer before the output,
`-F' sends a FormFeed at the end of output. There will be (additional)
30 mm left and 50 mm top margins. 75 DPI are assumed per default.
| | hp2xx -m pcx -f foo3.pcx -d300 -h80 -w150 -r90 -P2:4 foo.hp
|
PCX mode. Output goes into file `foo3.pcx'. A limiting rectangle
of 150 x 80 mm at 300 DPI is assumed. The picture will be rotated by
90 degrees. Only pages 2 to 4 of the multi-page HP-GL source is used (each
occurrence of HP-GL code PG; increments the internal page counter).
