<title>Taking A Snapshot</title>
|
|
|
|
<para> &ksnapshot; grabs an image of your entire desktop immediately after it is
|
|
started, but before it displays itself on screen. This allows you to quickly
|
|
create full-desktop screenshot images.</para>
|
|
|
|
<para>The snapshot taken by &ksnapshot; is displayed in the preview window,
|
|
which is located in the upper left of the &ksnapshot; application window.
|
|
Below is an example of the preview window from &ksnapshot;. Your preview
|
|
will differ depending on what you have displayed on the desktop.</para>

<textobject><phrase>&ksnapshot; Preview Window</phrase>
|
|
</textobject>
|
|
</mediaobject>
|
|
|
|
<para>The snapshot can be saved by clicking on
|
|
the <guibutton>Save As...</guibutton> button. This opens the standard &kde; save dialog,
|
|
where you can choose the filename, the folder location, and the format that your snapshot
|
|
will be saved in. If multiple snapshots are taken, the
|
|
filename is automatically incremented to prevent you from overwriting previous
|
|
snapshots. You may however edit the filename to anything you wish, including the name
|
|
of a previously saved snapshot. </para>
|
|
|
|
<para>To take a snapshot of a single window, select the <guilabel>Window
|
|
Under Cursor</guilabel> combo box entry (next to the <guilabel>Capture mode:</guilabel>
|
|
label), and then click on the <guibutton>New Snapshot</guibutton> button.</para>
|
|
|
|
<para>Depending on your <guilabel>Snapshot delay:</guilabel> settings you
|
|
get either a cross as the mouse pointer (for <guilabel>No delay</guilabel>),
|
|
or a standard mouse cursor which you can use to work with a program until
|
|
the delay is over and a snapshot is taken.</para>
|
|
|
|
<para>With <guilabel>No delay</guilabel>, the snapshot is taken immediately when you
|
|
click into a window.</para>
|
|
|
|
<para>&ksnapshot; will display the new snapshot in the preview
|
|
area, at which time you can choose to save the new image (by pressing
|
|
<guibutton>Save As...</guibutton>)
|
|
or to grab a new one, by pressing the
|
|
<guibutton>New Snapshot</guibutton> button.</para>
|
|
|
|
<para>To take a new snapshot of the entire desktop, select the
|
|
<guilabel>Full Screen</guilabel> combo box entry and then click on the
|
|
<guibutton>New Snapshot</guibutton> button.
|
|
&ksnapshot; will now capture the entire desktop if you press
|
|
<guibutton>New Snapshot</guibutton>.</para>
|
|
|
|
<para>Similarly, to take a snapshot of a region, select the
|
|
<guilabel>Region</guilabel> combo box entry and set the
|
|
<guilabel>Snapshot delay</guilabel> to <guilabel>No delay</guilabel>,
|
|
and then click on the <guibutton>New Snapshot</guibutton> button. The
|
|
mouse cursor will then change into a cross, and you can then use the
|
|
mouse to select the region you want to capture. </para>
|
|
|
|
<para>To take a new snapshot of a section of a window, select the
|
|
<guilabel>Section of Window</guilabel> combo box entry and then click on the
|
|
<guibutton>New Snapshot</guibutton> button. With <guilabel>No delay</guilabel>
|
|
you get a cross as the mouse pointer and you have to click once with the &LMB; into
|
|
the window. The section of the window under the mouse cursor is now highlighted
|
|
with a red border. Move the mouse to the wanted section and click the &LMB;
|
|
to capture the screenshot.

<title>&DCOP; Interface</title>
|
|
|
|
<para>&ksnapshot; can be scripted using its &DCOP; interface. This
|
|
chapter explains the various &DCOP; calls that you can use, and
|
|
provides some examples of how you can use them.</para>
|
|
|
|
<para>As with all &DCOP; calls, you need to specify the application
|
|
you want to interface with, and the particular interface. With &ksnapshot;
|
|
you need to identify which particular application, which is
|
|
<literal>ksnapshot-</literal> followed by the process number.</para>
|
|
|
|
<para>To start &ksnapshot; and obtain the right argument, use
|
|
<command>dcopstart ksnapshot</command>, which returns the
|
|
argument (such as <computeroutput>ksnapshot-20594</computeroutput>) on
|
|
standard output.</para>
|
|
|
|
<para>You can get a list of the available &DCOP; interfaces, use
|
|
the right arguments, as shown in this example:
|
|

<title>&DCOP; Access to Settings</title>
|
|
|
|
<para>For each of the settings that you can control with the
|
|
&GUI;, you can both obtain the current status of that setting,
|
|
and modify the setting, using &DCOP;.
|
|
</para>
|
|
|
|
<para>You can obtain the current capture mode using
|
|
<literal>grabMode</literal>, as shown below:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface grabMode</command>
|
|
</screen>
|
|
This will return <computeroutput>0</computeroutput> for full-screen capture,
|
|
<computeroutput>1</computeroutput> for window capture, and <computeroutput>2</computeroutput>
|
|
for region capture.
|
|
</para>
|
|
|
|
<para>You can set the capture mode using <literal>setGrabMode</literal>,
|
|
which requires an argument to identify the mode required (as for <literal>grabMode</literal>).
|
|
So you can set window capture mode (<command>1</command>), using:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface setGrabMode 1</command>
|
|
</screen>
|
|
</para>
|
|
|
|
<para>You can obtain the current timeout setting (the <guilabel>Snapshot delay:</guilabel>
|
|
GUI item) using <literal>timeout</literal>, as shown below:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface timeout</command>
|
|
</screen>
|
|
This will return the timeout setting in seconds, or zero if there is no delay
|
|
(capture on click).
|
|
</para>
|
|
|
|
<para>You can set the timeout using <literal>setTime</literal>,
|
|
which requires an argument to identify the timeout duration. So you can
|
|
set a delay of 4 seconds using:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface setTime 4</command>
|
|
</screen>
|
|
</para>
|
|
|
|
<para>You can obtain the path that the snapshot will be saved to using
|
|
<literal>url</literal>, as shown below:
|
|
<screen width="60">
|
|
<prompt>$</prompt><command>dcop ksnapshot-23151 interface url</command>
|
|
</screen>
|
|
This will return the filename, as a &URL; (eg as
|
|
<computeroutput>file:///home/bradh/test2.png</computeroutput>).
|
|
</para>
|
|
|
|
<para>You can set the path using <literal>setURL</literal>,
|
|
which requires a string argument to identify the new path. So you can
|
|
set the path to <literal>file:///home/bradh/snapshot.jpg</literal>
|
|
using:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface setURL file:///home/bradh/snapshot.jpg</command>
|

<title>Taking Screenshots with &DCOP;</title>
|
|
|
|
<para>
|
|
The key to taking screenshots with &DCOP; is use of <literal>slotGrab</literal>,
|
|
as shown below:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface slotGrab</command>
|
|
</screen>
|
|
</para>
|
|
|
|
<para>
|
|
This will take a snapshot using the current snapshot mode and timeout settings
|
|
(as described above). If you want to save the snapshot image, there are a
|
|
number of calls you can use. If you just want to save the image to the current
|
|
path (as returned by <literal>url</literal> or changed by
|
|
<literal>setURL</literal>), you can use <literal>slotSave</literal>, as shown
|
|
below:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface slotSave</command>
|
|
</screen>
|
|
</para>
|
|
|
|
<para>
|
|
If you want the user to be able to specify a filename (and path), you can use
|
|
<literal>slotSaveAs</literal>, which will bring up a standard &kde; file
|
|
save dialog.</para>
|
|
|
|
<para>
|
|
If you want to save the image to a different name (or path) without
|
|
changing the path with <literal>setURL</literal>, you can use
|
|
<literal>save</literal>, providing the &URL; to save to as an argument. So if you
|
|
want to save the snapshot to <filename>file:///tmp/tempshot.png</filename>, you
|
|
can do the following:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface save file:///tmp/tempshot.png</command>
|
|
</screen>
|
|
Note that this will return true if the snapshot was successfully saved, and false
|
|
otherwise. Also, you should be aware that if the file already exists, the user
|
|
will get a standard &kde; dialog that requires the user to decide whether to overwrite
|
|
or not.
|
|
</para>
|
|
|
|
<para>
|
|
In addition to saving the snapshot, you can also copy it to the clipboard, using
|
|
<literal>slotCopy</literal>, as shown below:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface slotCopy</command>
|
|
</screen>
|
|
</para>
|
|
|
|
<para>
|
|
If you need to select a window that may not be under the mouse cursor, you
|
|
can use <literal>slotMovePointer</literal>, passing the x position
|
|
(in screen pixels) and the y position (also in screen pixels) as arguments.
|
|
So to move the mouse to the top left hand corner of the screen (0,0), you
|
|
can do the following:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface slotMoveMouse 0 0</command>
|
|
</screen>

<sect1 id="dcop-print">

<para>
|

You can print the current screenshot (which may or may not have been saved)
|
|
using <literal>printSlot</literal>, as shown below:
|
|
<screen width="60">
|
|
<prompt>$</prompt> <command>dcop ksnapshot-23151 interface slotPrint</command>
|
