Creating Postscript output in Geocap is done by means of command psc of commands. They allow VTK data, graphics primitives, text, and axis to appear in Postscript format for later output to a hardcopy device.
- Conversion of all types of dataset and graphics, expect 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
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.
