Resource: device
| Resource | device |
|---|---|
| Overview | Specifies the output device. |
| Command Line | -de=device[,parameters] |
| Environment Variable | wxpdevice |
| Possible Values | |
| Default Value | d for display |
This resource is used to specify the output device used for producing the plots. For general purposes, the output device can be specified by the single character listed with each of the output types. For example, the display is "d". Additional information may be required for specific output types. For example, the window device needs the window ID. The syntax for each device type is listed below:
Display
d[,Xserver:display]
For the display output, the only additional parameter is the server name which is not often needed. If not specified, the value of the DISPLAY environment variable is used.
Window
w,[Xserver:display],[+window_id:]pixmap_id[:widthxheight][:colormap_id]
As with the display device, the server ID may be specified, otherwise the value of the DISPLAY environment variable is used (X windows only). The window ID and pixmap ID follows along with its size if it is different from 640x512 (the default window size). An additional parameter for the colormap can be specified if the window creation program is using a local colormap (X windows only). The last three parameters are specified with a colon ":" in between each parameter.
There is a second method for specifying window parameters:
w,[Xserver:display],filename
This reads the window information "+window_id:pixmap_id[:widthxheight][:colormap_id]" from the specified file. This can simplify use of wxploop since there needs to be a way to communicate the window information to other programs. This is essential for Windows programs since the Win32 prevents output to standard output. The filename is created with the "wxploop -ba -wn=filename" command.
Postscript
p[,file][,parameters...]
The output file is wxp.ps unless otherwise specified. The output file can be one of the following:
| File | Description |
|---|---|
| file | A specific output file |
| +file | Output to a file in append mode. Header and trailing showpage are omitted. This allows for multiple program to overlay graphics. Once the full file has been generated, the pscat program can be used to put the header and trailer on the file and spool to the printer. |
| |program | Pipes the output to a specific program. This is often used to spool the output to a print queue by using "|lp". |
The parameters are (multiple parameters are separated by commas):
| Parameter | Description |
|---|---|
| port | Portrait output |
| land | Landscape output (default) |
| eps | Encapsulated postscript |
| noeps | Standard postscript output |
| color | Setup for color output (colors automatically inverted) |
| gray | Setup for grayscale output (default) |
| scale=factor | Scale the output |
| lwidth=factor | Base line width (def=1.0) |
| sz=widthxheight | Set paper size in inches. |
| letter | Letter paper size (8.5x11") |
| legal | Legal paper size (8.5x14") |
| 11x17 | 11x17" paper size |
| a4 | A4 paper size (8.3x11.7") |
| a3 | A3 paper size (11.7x16.5") |
| ansid | ANSI D paper (22x34") |
The output file and parameters can be set with the use of the wxpps_print environment variable. PSPRINT can be used for backward compatibility.
setenv wxpps_print postscript_file
setenv wxpps_print '|program'
setenv wxpps_print +filename
The above parameters can be specified with the wxpps_param environment variable:
setenv wxpps_param letter,color
HPGL
h[,file][,parameters...]
The output file is wxp.hpgl unless otherwise specified. The output file can be one of the following:
| File | Description |
|---|---|
| file | A specific output file |
| +file | Output to a file in append mode. Header and trailer are omitted. This allows for mulitple program to overlay graphics. Once the full file has been generated, the hpglcat program can be used to put the header and trailer on the file and spool to the printer. |
| |program | Pipes the output to a specific program. This is often used to spool the output to a print queue by using "|lp". |
The parameters are (multiple parameters are separated by commas):
| Parameter | Description |
|---|---|
| port | Portrait output |
| land | Landscape output (default) |
| pcl | Includes PCL command to switch to HPGL (default) |
| lj | Laserjet setup (rotates paper) |
| rot=angle | Rotation angle |
| scale=factor | Scale the output |
| lwidth=factor | Base line width (def=0.2) |
| sz=widthxheight | Set paper size in inches. |
| letter | Letter paper size (8.5x11") |
| legal | Legal paper size (8.5x14") |
| 11x17 | 11x17" paper size |
| a4 | A4 paper size (8.3x11.7") |
| a3 | A3 paper size (11.7x16.5") |
| ansid | ANSI D paper (22x34") |
The output file and parameters can be set with the use of the wxphp_out environment variable.
setenv wxphp_out HPGL_file
setenv wxphp_out '|program'
setenv wxphp_out +filename
The above parameters can be specified with the wxphp_param environment variable:
setenv wxphp_param ansid,lwidth=.5
Metafile
m[,file]
The output file is wxp.meta unless otherwise specified. The output file can also be set with the wxpmeta_out environment variable.
