{{i18n|Taking a Screenshot}}<br />
<br />
== import ==<br />
An easy way to take a screenshot of your current system is using the {{Ic|import}} command:<br />
import -window root screenshot.jpg<br />
<br />
{{Ic|import}} is part of the {{Pkg|imagemagick}} package.<br />
<br />
Running {{Ic|import}} without the {{Ic|-window}} option allows selecting a window or an arbitrary region interactively.<br />
<br />
=== Screenshot of multiple X screens ===<br />
If you run twinview or dualhead, simply take the screenshot twice and use {{Ic|imagemagick}} to paste them together:<br />
import -window root -display :0.0 -screen /tmp/0.png<br />
import -window root -display :0.1 -screen /tmp/1.png<br />
convert +append /tmp/0.png /tmp/1.png screenshot.png<br />
rm /tmp/{0,1}.png<br />
<br />
=== Screenshot of individual Xinerama heads ===<br />
Xinerama-based multi-head setups have only one virtual screen. If the physical screens are different in height, you will find dead space in the screenshot. In this case, you may want to take screenshot of each physical screen individually. As long as Xinerama information is available from the X server, the following will work:<br />
#!/bin/bash<br />
xdpyinfo -ext XINERAMA | sed '/^ head #/!d;s///' |<br />
while IFS=' :x@,' read i w h x y; do<br />
import -window root -crop ${w}x$h+$x+$y head_$i.png<br />
done<br />
<br />
=== Screenshot of the active/focused window ===<br />
The following script takes a screenshot of the currently focused window. It works with EWMH/NetWM compatible X Window Managers. To avoid overwriting previous screenshots, the current date is used as the filename.<br />
#!/bin/bash<br />
activeWinLine=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)")<br />
activeWinId=${activeWinLine:40}<br />
import -window "$activeWinId" /tmp/$(date +%F_%H%M%S_%N).png<br />
<br />
Alternatively, the following should work regardless of EWMH support:<br />
import -window "$(xdotool getwindowfocus -f)" /tmp/$(date +%F_%H%M%S_%N).png<br />
<br />
== GIMP ==<br />
You also can take screenshots with GIMP (File -> Create -> Screenshot...).<br />
<br />
== xwd ==<br />
xwd is part of the {{Pkg|xorg-xwd}} package.<br />
<br />
Take a screenshot of the root window:<br />
xwd -root -out screenshot.xwd<br />
<br />
See the xwd man page for more information.<br />
<br />
== scrot ==<br />
{{Pkg|scrot}}, which is available in the [[Official Repositories|official repositories]], enables taking screenshots from the CLI and offers features such as a user-definable time delay. Unless instructed otherwise, it saves the file in the current working directory.<br />
scrot -t 20 -d 5<br />
<br />
The above command saves a dated {{ic|.png}} file, along with a thumbnail (20% of original), for Web posting. It provides a 5 second delay before capturing in this instance.<br />
<br />
You can also use standard date and time formatting when saving to a file. e.g.,<br />
scrot ~/screenshots/%Y-%m-%d-%T-screenshot.png<br />
<br />
saves the screenshot in a filename with the current year, month, date, hours, minutes, and seconds to a folder in your home directory called "screenshots" <br />
<br />
See {{Ic|man scrot}} for more information.<br />
<br />
== imlib2 ==<br />
<br />
{{Pkg|imlib2}} provides a binary {{ic|imlib2_grab}} to take screenshots. To take a screenshot of the full screen, type:<br />
imlib2_grab screenshot.png<br />
<br />
Note that {{Pkg|scrot}} actually uses imlib2.<br />
<br />
== KDE ==<br />
If you use [[KDE]], you might want to use KSnapshot, which can also be activated using <Prt Scr>.<br />
<br />
KSnapshot is provided by the {{Pkg|kdegraphics-ksnapshot}} package in [extra].<br />
<br />
== GNOME ==<br />
[[GNOME]] users can press <Prt Scr> or Apps->Accessories->Take Screenshot.<br />
<br />
{{Note|If <Prt Scr> complains about not finding gnome-screenshot or there is no "Take Screenshot" entry in your menu, you will need to install the {{Pkg|gnome-utils}} package from [extra].}}<br />
<br />
== Other Desktop Environments or Window Managers ==<br />
For other desktop environments such as [[LXDE]] or window managers such as [[Openbox]] and [[Compiz]], one can add the above commands to the hotkey to take the screenshot. For example,<br />
import -window root ~/Pictures/`date '+%Y%m%d-%H%M%S'`.png<br />
Adding the above command to the <Prt Scr> key to Compiz allows to take the screenshot to the Pictures folder according to date and time.<br />
Notice that the {{ic|rc.xml}} file in Openbox does not understand commas; so, in order to bind that command to the <Prt Scr> key in Openbox, you need to add the following to the keyboard section of your {{ic|rc.xml}} file:<br />
<br />
<nowiki><!-- Screenshot --></nowiki><br />
<keybind key="Print"><br />
<action name="Execute"><br />
<command>sh -c "import -window root ~/Pictures/`date '+%Y%m%d-%H%M%S'`.png"</command><br />
</action><br />
</keybind><br />
<br />
== Virtual console ==<br />
Install a [[framebuffer]] and use {{Pkg|fbgrab}}, {{Pkg|fbshot}}, or {{Pkg|fbdump}} to take a screenshot.<br />
<br />
If you merely want to capture the text in the console and not an actual image, you can use {{Ic|setterm}}, which is part of the {{Pkg|util-linux}} package. The following command will dump the textual contents of virtual console 1 to a file screen.dump in the current directory:<br />
sudo setterm -dump 1 -file screen.dump<br />
<br />
Root permission is needed because the contents of {{ic|/dev/vcs1}} need to be read.</div>Subject17
