<para>&kde; comes with a full set of icons in several sizes. These icons
|
|
are being used all over &kde;: the desktop, the panel, the &konqueror; file
|
|
manager, in every toolbar of every &kde; application, etc. The icons
|
|
control module offers you very flexible ways of customizing the way &kde;
|
|
handles icons. You can:</para>

|
|
|
|
<important><para>Please note that some of these settings may depend on

your selected icon theme. &kde; comes with two icon themes by default,

&kde;-Classic (HiColor) and Crystal SVG. There is also a low color theme

|
in the kdeartwork package, along with others.</para></important>

<para>Starting at the top, you can see some example icons. These change

|
in appearance depending on the icon theme you select. Most default
|
|
installations will have only one icon theme available, the &kde; default
|
|
Crystal SVG theme. There are others contained separately in the
|
|
kdeartwork package, and you can download more from the Internet.</para>

|
<para>Looking at this second page of the icons control module, you
|
|
will see two areas:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>An area labelled <guilabel>Use of Icon</guilabel>. Here you can
|
|
choose which particular usage of icons you want to configure, for
|
|
example <guilabel>Toolbar</guilabel> or <guilabel>Panel</guilabel>.</para>
|
|
</listitem>
|
|
|
|
<listitem> <para>A preview area where you can see how
|
|
icons of the selected kind will look using the current
|
|
settings. Note that the state of this preview also depends on the icon
|
|
state selected in the effects below (do not worry
|
|
about that now, we will explain that below). </para> </listitem>
|
|
</itemizedlist>
|
|
|
|
<para>When you want to configure icons, first select the usage of icons
|
|
you want to configure. Change the settings until you like the
|
|
preview. You can then choose a different icon usage and configure
|
|
that. At the end, if you are satisfied with your settings, click
|
|
<guibutton>OK</guibutton> or <guibutton>Apply</guibutton> to take the
|
|
changes in effect.</para>
|
|
|
|
<para>There are two further options to consider,
|
|
<guilabel>Size</guilabel> and <guilabel>Effects</guilabel>. </para>
|
|
|
|
<sect3 id="icons-use-size">
|
|
<title>Icon Size</title>
|
|
|
|
<para>You have two options relating to icon sizes. First, you can choose
|
|
from a list of icon sizes. Second, you can tell &kde; to draw all icons
|
|
using double sized pixels. The largest icon sizes are especially useful
|
|
for visually impaired people.</para>
|
|
|
|
<para>Which sizes will be offered by the icon size listbox depends on
|
|
the icon theme you have selected in the icon themes control module. For
|
|
example, the low color icon theme only offers the sizes 16 and 32 for
|
|
desktop icons and 16, 22 and 32 for toolbar icons. The HiColor theme
|
|
offers icon sizes 16, 32 and 48 as well as sizes from 64 to 128.
|
|
However, as &kde; can not have all these icon sizes in store, icons
|
|
using size 64 to 128 will be automatically generated which may result in
|
|
a loss of quality.</para>
|
|
|
|
<para>If the icon sizes offered by your chosen icon theme are not enough
|
|
for you, there is still the option <guilabel>Double-sized
|
|
pixels</guilabel>. If this option is selected, all icons will have
|
|
double sized pixels, &ie; a 2x2 block instead of normal pixels. While
|
|
this makes it possible to achieve very large icon sizes, the quality is
|
|
poor: icons will look <quote>blocky</quote>, an effect you may remember
|
|
if you've grown up using a Sinclair ZX Spectrum or similar. If this is
|
|
an option for you, using the large sizes offered by &kde;'s HiColor
|
|
icon theme will always result in a much better quality than using the
|
|
low color icon theme with double sized pixels.</para>
|
|
<!--
|
|
<para>You can also choose to have smoothed icons, an effect similar to
|
|
anti-aliasing of fonts. Enable the checkbox <guilabel>Blend alpha
|
|
channel</guilabel> to see this in action, but note that it will slow
|
|
down graphics on a slower computer.</para>
|
|
-->
|
|
|
|
<para>You can also choose animated icons. Many of the icons have
|
|
animations associated with them. Enable the checkbox labelled
|
|
<guilabel>Animate Icons</guilabel>, to enable this effect, but note
|
|
that it may appear slow or jerky if your graphics card is old or you
|
|
are low on memory.</para>

|

|
|
<para>Finally you can configure certain <quote>filters</quote> to be
|
|
applied on icons which are in one of three states:</para>
|
|
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term><guilabel>Default</guilabel></term>
|
|
<listitem><para>This is how the icon will look normally.</para></listitem>
|
|
</varlistentry>
|
|
<varlistentry>
|
|
<term><guilabel>Active</guilabel>:</term>
|
|
<listitem><para>This is how the icon will look when the mouse cursor is over the icon.</para></listitem>
|
|
</varlistentry>
|
|
<varlistentry>
|
|
<term><guilabel>Disabled</guilabel>:</term>
|
|
<listitem><para>This is how the icon will look if its corresponding action is
|
|
disabled, &ie; clicking on it will not lead to any
|
|
result.</para></listitem>
|
|
</varlistentry>
|
|
</variablelist>
|
|
|
|
<para>Select one of these states, and press the <guibutton>Set
|
|
Effect...</guibutton> button to configure a corresponding icon effect.
|
|
Please note that this configuration will only affect icons of the
|
|
currently selected <guilabel>Use of Icon</guilabel> category (see
|
|
above): configuring an effect for active icons, while
|
|
<guilabel>Toolbar</guilabel> icon usage is selected, will
|
|
<emphasis>not</emphasis> affect active icons used in other
|
|
places.</para>
|
|
|
|
<para>Below the list of icon states there are two options: you can
|
|
configure an effect and you can select the
|
|
<guilabel>Semi-transparent</guilabel> option, which will make the
|
|
background <quote>shine through</quote> the icon. To the right of the
|
|
effects list box there is a slider button to pass additional parameters to
|
|
a filter for colours and <guilabel>Amount</guilabel>.</para>
|
|
<!-- TODO: Figure out what 'amount' really means -->
|
|
|
|
<para>The following effects can be applied to icons:</para>

effect.</para></listitem>

<term><guilabel>To Gray</guilabel>:</term>
|
|
<listitem><para>This filter will apply a grayish look to the icon. Click
|
|
<guibutton>Setup...</guibutton> to configure the intensity of this filter. Note
|

that it is customary for most user interfaces to use this effect for disabled
|
|
icons only.</para></listitem>

<varlistentry>
|
|
<term><guilabel>Colorize</guilabel>:</term>
|
|
<listitem><para>Icons will be colorized using a custom color. For example, you

may configure active icons (&ie; the icon the mouse cursor is over) to

shine golden. Use the color and <guilabel>Amount</guilabel> buttons to configure the used color and the intensity of the colorization.</para></listitem>

<term><guilabel>Gamma</guilabel>:</term>

<listitem><para>A different gamma value will be applied to all icons. If you're

no photographer and don't know what Gamma is: it's quite similar to what people

call contrast. Just play around with the gamma settings by clicking on
|

<guibutton>Setup...</guibutton> to get a feeling for this

effect.</para></listitem>

<term><guilabel>Desaturate</guilabel>:</term>
