If you want to save the snapshot image, there are a +number of calls you can use.

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>$</prompt> <command>dcop ksnapshot-23151 interface slotMoveMouse 0 0</command> +</screen> +</para> +</sect1> + +<sect1 id="dcop-print"> +<title>Printing Screenshots with &DCOP;</title> + +<para> +You can print the current screenshot (which may or may not have been saved) +using <literal>printSlot</literal>, as shown below: +<screen width="60"> +<prompt>$</prompt> <command>dcop ksnapshot-23151 interface slotPrint</command> +</screen> +</para> + +<para> +Note that this will bring up the normal &kde; print dialog, which may require +user interaction. +</para> + +</sect1> + +<sect1 id="dcop-exit"> +<title>&DCOP; Application control</title> + +<para> +You can cause &ksnapshot; to exit by using <literal>exit</literal>, +as shown below. +<screen width="60"> +<prompt>$</prompt> <command>dcop ksnapshot-23151 interface exit</command> +</screen> +</para> + +</sect1> + +</chapter> + +<chapter id="credits"> + +<title>Credits and License</title> + +<para>Program copyright</para> +<itemizedlist> +<listitem><para>1997-2000 &Richard.J.Moore; &Richard.J.Moore.mail;</para></listitem> +<listitem><para>2000 &Matthias.Ettrich; &Matthias.Ettrich.mail;</para></listitem> +</itemizedlist> + +<para>Documentation based on the original, copyright 1997-2000 &Richard.J.Moore; +&Richard.J.Moore.mail;</para> +<!-- TRANS:CREDIT_FOR_TRANSLATORS --> + +&underFDL; +&underGPL; + +</chapter> + +&documentation.index; +</book> + +<!-- +Local Variables: +sgml-minimize-attributes: nil +sgml-general-insert-case: lower +End: +--> + + + + |
