The Filters menu

<p>
In GIMP terminology, a <span class="emphasis"><em>filter</em></span> is a plug-in
that modifies the appearance of an image, in most cases just the
active layer of the image. Not all of the entries in this menu
meet that definition, however: the word "filter" is often abused
to mean any plug-in regardless of what it does. Indeed, some of
the things you will find in this menu do not modify images at
all.
</p>
<p>
With the exception of the top three items, all of the entries in
this menu are provided by plug-ins. Each plug-in decides for
itself where it would like its menu entry to be placed.
Therefore, the appearance of this menu can be completely different
for each user. In practice, though, the appearance does not vary
all that much, because most plug-ins come with GIMP when it is
installed, and of course they are always in the same places in the
menu.
</p>
<p>
Plug-ins are not restricted only to the Filters menu: a plug-in
can request to be placed in any menu. Indeed, a number of GIMP's
basic functions (for example, "Semi-flatten" in the Layer menu) are
implemented by plug-ins. But the Filters menu is the default place
for a plug-in to locate itself.
</p>
<p>
For general information on plug-ins and how to use them, see the
section on <a href="ch02s08.html" title="8. Plugins">Plugins</a>.
Information on the filters that are provided with GIMP can be
found in the <a href="ch06.html" title="Chapter 6. Filters">Filters</a> chapter. For
filters you install yourself, you will of course have to obtain
information elsewhere.

<h3 class="title"><a id="gimp-filter-repeat"></a>Repeat Last</h3>

<p>
This command can be accessed from an image menubar as
<span class="guimenu">Filters</span>-><span class="guimenuitem">Repeat "<i class="replaceable"><tt>filter</tt></i>"</span>,
or by using the keyboard shortcut
<span><b class="keycap">Ctrl</b></span>-<span><b class="keycap">F</b></span>.
</p>
<p>
"Repeat Last" repeats the most recently executed plugin, using
the same settings at the last time it was run. It does not show
a dialog or request confirmation.
</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<table border="0" summary="Note">

<td rowspan="2" align="center" valign="top" width="25">

It is important to realize that this command repeats the most
recently executed <span class="emphasis"><em>plugin</em></span>, regardless of
whether it can be found in the Filters menu.

<h3 class="title"><a id="gimp-filter-reshow"></a>Re-show Last</h3>

<p>
This command can be accessed from an image menubar as
<span class="guimenu">Filters</span>-><span class="guimenuitem">Re-show "<i class="replaceable"><tt>filter</tt></i>"</span>,
or by using the keyboard shortcut
<span><b class="keycap">Ctrl</b></span>-<span><b class="keycap">Shift</b></span>-<span><b class="keycap">F</b></span>.
</p>
<p>
"Re-show Last" interactively runs the most recently executed
plugin. If the plugin is one that uses a dialog window, it does
so here, with the settings initialized to the values you used
the last time you ran the plugin. (Assuming the plugin is
correctly programmed, that is.)
</p>
<div class="tip" style="margin-left: 0.5in; margin-right: 0.5in;">
<table border="0" summary="Tip">
<tr>
<td rowspan="2" align="center" valign="top" width="25">
<img alt="[Tip]" src="../images/tip.png" />
</td>
<th align="left">Tip</th>
</tr>
<tr>
<td colspan="2" align="left" valign="top">
<p>
It is very common, especially for plugins that lack a preview,
to have to adjust parameters several times before the results
are satisfactory. The most efficient way to do this is to
memorize the keyboard shortcuts for "undo" followed by "re-show
last":
<span><b class="keycap">Ctrl</b></span>-<span><b class="keycap">Z</b></span>
followed by
<span><b class="keycap">Ctrl</b></span>-<span><b class="keycap">Shift</b></span>-<span><b class="keycap">F</b></span>.

<div class="titlepage">
<div>
<div>
<h3 class="title"><a id="id3355590"></a>Reset All Filters</h3>
</div>
</div>
</div>
<p>
This command can be accessed from an image menubar as
<span class="guimenu">Filters</span>-><span class="guimenuitem">Reset All Filters...</span>.
</p>
<p>
Normally, each time you run an interactive plugin, the dialog
comes up with settings initialized to the values you used the
last time you ran it. Sometimes this can be very annoying, if
you mess up the values and don't remember what they were
originally. One way to recover is to exit from GIMP and start
again, but this command provides a slightly less desperate
solution: it resets the values for <span class="emphasis"><em>all</em></span>
plugins to their defaults. Because it is a dramatic step, it
asks you to confirm that you really want to do it. Be careful:
this command is not undoable.
