Making a Screen Dump with `xwd' |
 |
The xwd client allows you to take a "picture" of a window that is displayed on the screen and store it in a file. The filed picture can then be printed, edited, or redisplayed. You select the window to be dumped either by clicking the mouse on it or by specifying the window name or id on the command line.
The resulting file is called an xwd-format bitmap file or an xwd screen dump. All of the figures used in this manual are xwd screen dumps.
The syntax for xwd is as follows:
where options are:
- -help
Provides a brief description of usage and syntax.
- -id id
Specifies the window to be dumped by its id rather than using the mouse to select it.
- -add
Adds value to every pixel.
- -name name
Specifies the window to be dumped by its name rather than using the mouse to select it.
- -root
Specifies that the window to be dumped is the root window.
- -add value
Add value to every pixel. value is signed.
- -nobdrs
Dumps the window without borders.
- -out filename
Specifies that the screen dump is to be stored in the file filename.
- > filename
Specifies that the screen dump is to be stored in the file filename.
- -xy
Selects `XY' format of storage instead of the default `Z' format.
- -display display
Specifies the screen that contains the window to be dumped.
This first example stores a window in a file named savewindow, using the pointer to determine which
window you want.
Display an hpterm or xterm window.
Type:
xwd -out savewindow Return
|
The pointer changes shape, signifying you can select a window to dump.
Move the pointer into the window you want to dump. Press and release any pointer button. After the image is captured, the cursor changes back to its normal shape and the window is stored in the file savewindow.
If you know the name of the window you want to dump, you don't need to use the pointer at all. This example dumps the window named "calendar" to a file named calendar.dump.
xwd -name calendar -out calendar.dump Return
