Keywords

Each type of device uses its own unique set of keywords. For a description of these keywords, see Appendix B: Output Devices and Window Systems.

Discussion

note

Do not use the DEVICE command when VDA Tools or the Navigator are running. To do so can cause PV‑WAVE to crash. VDA Tools and the Navigator expect to be running under the X Window system or Microsoft Windows. Using DEVICE to switch to another device is not supported. VDA Tools set the device internally, e.g., when printing. If you are on a 24-bit display, but are not using the VDA Tools for real 24 bit applications, then set your display to 8-bit before starting any VDA Tools. Issuing the command DEVICE, Pseudo=8 can cause PV‑WAVE to crash under these circumstances.

The graphics procedures and functions are device-independent. This means that PV-WAVE presents you with a consistent interface to all devices.

However, most devices have extra abilities that are not directly available through this interface. Use DEVICE with the appropriate keywords to control these additional capabilities.
