SET_PLOT Procedure

Specifies the device type used by PV-WAVE graphics procedures.

SET_PLOT, device

device A scalar string giving the name of the device to use. This parameter is case-insensitive.

Copy If present and nonzero, PV-WAVE's internal color table is copied into the device. This is the preferred method if you are displaying graphics and each color index is explicitly loaded.

Interpolate If present and nonzero, the color table of the new device is loaded by interpolating the old color table to span the new number of color indices. This method works best when displaying images with continuous color ranges.

The following are valid device names. These devices are explained in detail in Appendix , Output Devices and Window Systems.

If the Copy keyword parameter is set, the color table copying is straightforward as long as both devices have the same number of color indices. However, if the new device has more colors than the old device, some color indices will be invalid. If the new device has less colors than the old, not all the colors are saved.
