XGRAB(1X)XGRAB(1X)NAMExgrab - interactive front for xgrabsc, an X-Windows image grabber
SYNOPSISxgrabDESCRIPTIONxgrab lets you grab arbitrary rectangular images from an X server and
writes them to files or commands (such as lpr) in a variety of formats.
xgrab is a front for the xgrabsc program. Read the man page for
xgrabsc for a description of the options presented by xgrab. The
xgrabsc program has more options than are presented through the xgrab
interface. In particular, xgrab does not allow you to grab areas of
the screen by specifying numeric coordinates, or grab subareas of a
window through offset coordinates.
After selecting options from the various categories presented, press
the OK button to have xgrab run xgrabsc to let you grab an image from
the screen. After you press OK, xgrab's window will disappear and
xgrabsc will gain control until the grabbing process is finished.
Afterwards, the xgrab window will reappear.
OPTIONS
Xgrab responds to the standard application options, such as -display.
See the man page for X for a complete list.
You can also override the default xgrab settings in your .Xdefaults.
See the examples section below for instructions.
RESOURCES
The XGrab resource file, XGrab.ad, contains a complete specification of
the resources of all the widgets used in the xgrab window. Global
resources, such as default font and color, are at the bottom of the
file.
EXAMPLES
The To Command output option may be used to pipe xgrabsc output to pro‐
grams. The most common commands are lpr for Postscript output, and
xwud for X-Window Dump output. Programs that do not accept piped input
should not be used in To Command.
You can also get fancy and pipe the output through more than one com‐
mand, such as tee screen.dmp | xwud, to store the grabbed image and get
a preview window.
Default settings for xgrab can be made in your .Xdefaults file. For
the Athena toolkit version of xgrab, Toggle buttons can be set/unset
through their .state attribute, and text field strings can be set
through their *string attribute. For the Motif toolkit version (which
has diamond-shaped buttons for radio buttons), toggle buttons can be
set/unset through their .set attribute and text field strings can be
set through their *value attribute.
For example, to set the default paper size for postscript output, put
these lines in your .Xdefaults (and use xrdb to load them into the
server!):
XGrab*.pageWidthText*string: 8.5
XGrab*.pageHeightText*string: 11.0
or
XGrab*.pageWidthText*value: 8.5
XGrab*.pageHeightText*value: 10.0
To set the default output type to XWD, put these lines in your .Xde‐
faults:
XGrab*.ps.state: 0
XGrab*.xwd.state: 1
