The expg2hpgl tool converts EXPRESS-G diagrams to HP-GL plotter commands. The output may be sent to a file or piped directly to a plotter or another program.
This tool is intended primarily for the UNIX platform, but is also available on Windows. Windows users can also print directly from the EXPRESS-G editor.
expg2hpgl [options] <expg-file>
The EXPRESS-G to HP-GL converter accepts the following options.
- -color1pen <pen-number>
- This allows the user to set the 'color1' or blue pen (default 2).
- -color2pen <pen-number>
- This allows the user to set the 'color2' or green pen (default 3).
- -color3pen <pen-number>
- This allows the user to set the 'color3' or red pen (default 4).
- -color4pen <pen-number>
- This allows the user to set the 'color4' or grey pen (default 5).
- -f or -file <output-file>
- Write HPGL data to a file. By default the tool writes to standard output.
- -nc / -nocolor
- Do not generate color commands for the plotter. By default, pens 1,2,3 and 4 are used to show color.
- -normalpen <pen-number>
- This allows the user to set the 'normal' or black pen (default 1).
- -pages <start>[-<end>]
- Allows the user to select a group of pages to print. If you do not include a min or max page (e.g. "-5" or "10-") it will assume the start or end, respectively, of the document.
- -thinthick <number>
- Sets the thickness that a thin line should be restroked to (if supported by plotter).
- -thickthick <number>
- Sets the thickness that a thick (inheritance) line should be restroked to (if supported by plotter).
- Give more information about the conversion process. It is useful for tracking the progress through large schemas.
The expg2hpgl tool generates a stream of HP-GL drawing commands from an EXPRESS-G diagram. The generated HP-GL is similar to the display of expgedit, but lines will go through boxes, since HP-GL cannot erase areas. Also fonts on plotters tend to be limited. However, plotters allow for extremely large plots.
By default, the HP-GL is written to standard output. If this is not desired you can use either the -file or the redirect operator send the output to a file.
