Specifies the device and other parameters for graphics
displays.
Fname
Device name, file name, or keyword, as listed below:
<device name> | — | Any valid graphics display device name (e.g., X11, 3-D etc.). Defaults to X11 for most systems. See Getting Started with Graphics in the Basic Analysis Guide for details. A device name must be defined before activating the Graphical User Interface (GUI). Once the GUI is activated, the device name cannot be changed for that session, except for switching between X11 and X11C. |
<filename> | — | Name of graphics file to which graphics displays are
to be diverted (248 characters maximum). Should not be the same as
a valid device name or any other |
TERM | — | Graphics displays are switched back to the last-specified device name. |
CLOSE | — | This option purges the graphics file buffer. The CLOSE option should be issued any time you are changing graphics devices or file output types during a session. Graphics displays are switched back to the last-specified device name, and any open graphics files are closed. The CLOSE option is similar to the TERM option, however, with the CLOSE option, another process, such as the DISPLAY program, can access the data in the graphics file. The CLOSE option causes graphics file buffers to be flushed to the graphics file. |
FILE | — | Graphics displays are switched back to the last-specified file name. |
OFF | — | Graphics display requests are ignored. |
(blank) | — | If blank in interactive mode, graphics will be displayed on screen as requested by display commands (no file written); If blank in batch mode, graphics data will be written to Jobname.GRPH. |
PSCR | — | Creates PostScript graphic files
that are named Jobname |
HPGL | — | Creates Hewlett-Packard Graphics
Language files that are named Jobname |
HPGL2 | — | Creates Hewlett-Packard Graphics
Language files that are named Jobname |
JPEG | — | Creates JPEG files that are named Jobname |
TIFF | — | Creates tagged image format files
that are named Jobname |
PNG | — | Creates PNG (Portable Network Graphics)
files that are named Jobname |
VRML | — | Creates Virtual Reality Meta Language
files named Jobname000.wrl that can be displayed
on 3-D Internet web browsers. Ignores the |
Option
Assign a file name extension or specify reverse video output:
VECT
Specifies raster or vector display mode. This affects
area, volume, and element displays, as well as geometric results displays
such as contour plots. See the /DEVICE command
for an alternate way to toggle between raster and vector mode. Changing VECT
also resets the /TYPE command
to its default.
0 | — | Raster display (color filled entities; default) |
1 | — | Vector display (outlined entities; i.e., "wireframe") |
NCPL
Sets the number of color planes (4 to 8). Default
is device-dependent. NCPL
is not supported
by all graphics devices.
For interactive runs, display is shown on the screen; for batch runs, display commands are ignored (graphics file not written).
Specifies the device to be used for graphics displays, and specifies other graphics display parameters. Display may be shown at the time of generation (for interactive runs at a graphics display terminal) or diverted to a file for later processing with the DISPLAY program. Issue /PSTATUS for display status.
Batch runs do not have access to the fonts available on your system. The Courier and Helvetica font files used for JPEG, PNG and TIFF batch output are copyrighted by Adobe Systems Inc. and Digital Equipment Corp. Permission to use these trademarks is hereby granted only in association with the images described above. Batch run JPEG output is produced at the default quality index value of 75, unless specified otherwise.
Interactive displays default to eight color planes (NCPL
= 8) for most monitors, while graph file output
defaults to eight color planes for VRML output, and four color planes
for PSCR, HPGL, HPGL2, JPEG, PNG, TIFF and FILE33.
This command is valid in any processor.
