<para>You can easily extend &kappname; by defining external tools. These tools
|
||
|
|
are accessible from the contextual popup menu which appears when
|
||
|
|
right-clicking on a thumbnail or in the image view. Look in the
|
||
|
|
<menuchoice><guimenu>External Tools</guimenu></menuchoice> entry.</para>
|
||
|
|
|
||
|
|
<para>&kappname; comes with a few predefined external tools, but it's very
|
||
|
|
easy to add more through the <guilabel>Configure External Tools</guilabel> dialog. You can open
|
||
|
|
it from <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure
|
||
|
|
External Tools...</guimenuitem></menuchoice>.

<para>In this example, I defined an external tool which will call Exiftran to
|
||
|
|
regenerate the EXIF tags for JPEG images. Here is a more detailed description
|
||
|
|
of its definition:</para>

<itemizedlist>

<listitem>
|
||
|
|
<para>The <guilabel>Name:</guilabel> field contains the description of your
|
||
|
|
tool, has it will appear in the menu.

</listitem>

<listitem>
|
||
|
|
<para>The <guilabel>Command:</guilabel> field contains the command which
|
||
|
|
will be run when this tool is invoked.
|
||
|
|
Click on the little question mark on the right of the field to get a list
|
||
|
|
of the keywords you can use in this field. These keywords will get
|
||
|
|
expanded to the image files.

The button on the right lets you associate an icon with your tool.

<para>
|
||
|
|
The <guilabel>File Associations</guilabel> group indicates what type of
|
||
|
|
files this tool can work with. Your tool will only appear in the
|
||
|
|
<menuchoice><guimenu>External Tools</guimenu></menuchoice> menu if the
|
||
|
|
selected files are of the correct type. In my example, this tool is only
|
||
|
|
valid with JPEG images, so I choose <guilabel>Custom:</guilabel>, then
|
||
|
|
<guilabel>image/jpeg</guilabel> and <guilabel>image/pjpeg</guilabel>.
