SET_PLOT Procedure

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

Usage

SET_PLOT, device

Input Parameters

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

Keywords

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.

Discussion

Valid Device Names lists valid device names. These devices are explained in detail in Output Devices and Window Systems .

Valid Device Names
Name	Device
CGM	Computer Graphics Metafile format
HP	HPGL device
PCL	PCL device
PM	Pixel Map
PS	PostScript device
WIN32	Windows
WMF	Windows Metafile
X	X Window System
Z	Z-buffer pseudo device

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.
