Postscript output in Geocap is mainly created by using the psc command. They allow VTK data, graphics primitives, text, and axis to appear in Postscript format for later output to a hardcopy device.
Main Postscript features
- Conversion of all types of dataset and graphics, except gradient coloring.
- Flexible viewport setting on device
- Axis. Parameters set by system (default) or by user
- Text, where the user may specify font, size, rotation and position
- Scaling
- Graphics primitives such as lines and rectangles
- Gridlines
- Very compact Postscript file using a compression filter
While almost any kind of plotting feature can be created using the above features in combination with the Tcl programming language, most users will eventually expect a higher level interface; this task is currently being worked on.
