This tool provides services to produce copies of the drawing canvases of Viewerdisplaypanel tools. PostScript and bitmap output is available at present.
Graphical User Interface
This tool
controls two forms of hardcopy output: PostScript for printing, and
X-Windows pixmap format which can be easily converted to GIF, JPEG or
other bitmap formats. To initiate printing of what is visible on the
Viewerdisplaypanel tool simply press the Print... button at the bottom
of the window, or select Print manager... from the File
menu. This will bring up the GUI for this tool which allows you
to set some basic output parameters, most of which are only important
for PostScript output (as indicated by the [PS] prefix:
Output file
This can be left <unset>, and the Viewer will automatically create a unique filename for your output. Otherwise, just type in a specific name for your output file.
[PS] Output media
You may select to print to A4 or US Letter paper.
[PS] Orientation
Selection from portrait or landscape to orient the output on the selected paper.
[PS] Resolution
You may choose the resolution of your output here. Bear in mind that the size of the output file for raster images will generally grow as the square of this number, and likewise the speed with which the hardcopy will be generated and printed. For test output, generally leave the resolution quite low, and only increase it to your printer resolution for final hardcopy output. This setting enables you to tune the output to the exact resolution of your hardcopy device.
[PS] Magnification
You can scale your output by any factor between 0 and 1.
[PS] Write EPS format?
Set this option to True if you want encapsulated PostScript output.
Once you have filled in the desired options, you need to hit one of three buttons at the bottom of the Print manager GUI:
Save XPM
This button will write an X-Windows Pixmap copy of the Viewerdisplaypanel tool contents to a file on disk. The output will be an exact copy of what is displayed on-screen, and then a utility like 'xv' can be used to convert the output file to a GIF file, or a JPEG file, or whatever takes your fancy.
Save PS
This button will write a PostScript file which aims to duplicate what is seen on-screen in a higher-resolution mode suitable for printing. Every attempt is made to preserve the aspect ratio of the on-screen display.
This button will first write a PostScript file as if the Save PS button had been pressed, and will then bring up a simple window which allows you to direct the output to a printer, to a previewer, or to cancel the operation.
Press Dismiss to cancel printing.
