This page lets you customize the amount of system memory allocated
for various purposes. It also allows you to disable the
confirmation dialogs that appear when you close unsaved images,
and to set the size of thumbnail files that GIMP produces.

<b>Resource Consumption</b>
</p>
<dl>
<dt>
<span class="term">Minimal number of undo levels</span>
</dt>
<dd>
<p>
GIMP allows you to undo most actions by maintaining an "Undo
History" for each image, for which a certain amount of
memory is allocated. Regardless of memory usage, however,
GIMP always permits some minimal number of the most recent
actions to be undone: this is the number specified here.
See <a href="ch02s04s05.html" title="4.5. Undoing">Undoing</a> for more
information about GIMP's Undo mechanism.
</p>
</dd>
<dt>
<span class="term">Maximum undo memory</span>
</dt>
<dd>
<p>
This is the amount of undo memory allocated for each image.
If the Undo History size exceeds this, the oldest points are
deleted, unless this would result in fewer points being
present than the minimal number specified above.
</p>
</dd>
<dt>
<span class="term">Tile cache size</span>
</dt>
<dd>
<p>
This is the amount of system RAM allocated for GIMP image
data. If GIMP requires more memory than this, it begins to
swap to disk, which may in some circumstances cause a
dramatic slowdown. You are given an opportunity to set this
number when you install GIMP, but you can alter it here. See
<a href="ch02.html#gimp-using-setup-tile-cache" title="How to Set Your Tile Cache">How to Set Your
Tile Cache</a> for more information.
</p>
</dd>
<dt>
<span class="term">Maximum new image size</span>
</dt>
<dd>
<p>
This is not a hard contraint: if you try to create a new
image larger than the specified size, you are asked to
confirm that you really want to do it. This is to prevent
you from accidentally creating images much larger than you
intend, which can either crash GIMP or cause it to respond
verrrrrrrry slowwwwwwwwly.

<p class="title">
<b>Image Thumbnails</b>
</p>
<dl>
<dt>
<span class="term">Size of thumbnails</span>
</dt>
<dd>
<p>
This options allows you to set the size of the thumbnails
shown in the File Open dialog (and also saved for possible
use by other programs). The options are "None",
"Normal (128x128)", and "Large (256x256)".
</p>
</dd>
<dt>
<span class="term">Maximum filesize for thumbnailing</span>
</dt>
<dd>
<p>
If an image file is larger than the specified maximum size,
GIMP will not generate a thumbnail for it. This options
allows you to prevent thumbnailing of extremely large
image files from slowing GIMP to a crawl.

<p class="title">
<b>Saving Images</b>
</p>
<dl>
<dt>
<span class="term">Confirm closing of unsaved images</span>
</dt>
<dd>
<p>
Closing an image is not undoable, so by default GIMP asks
you to confirm that you really want to do it, whenever it
would lead to a loss of unsaved changes. You can disable
this if you find it annoying; but then of course you are
responsible for remembering what you have and have not
saved.
</p>
</dd>
<dt>
<span class="term">Size of thumbnail files</span>
</dt>
<dd>
<p>
Here you can set the size of thumbnail files that GIMP
generates. Regardless of this value, GIMP will still be
capable of <span class="emphasis"><em>reading</em></span> thumbnail files of
any size.
