For example, some of the themes are designed for users with low vision. Several versions of icons might be required so that the icon can be displayed properly in each theme.</para> <para>You might need to install a new icon for an application. When you install a new icon, you must create several versions of the icon, so that the icon displays correctly in the themes. You must create several versions of the following types of icon:</para> <itemizedlist> <listitem> <para>Icons that are used within applications in the GNOME Desktop.</para> </listitem> <listitem> <para>Icons that are used internally by GTK+ applications, or GTK+ stock icons.</para> </listitem> </itemizedlist> <para>When you install a new icon, you must create several versions of the icon, so that the icon displays correctly in the themes. You can create the icons in several formats, for example Portable Network Graphic (PNG) format. The suggested size of icons for the desktop environment is 48 pixels by 48 pixels. At this size, most themes can rescale the icons.</para> <para>When you install a new icon, create the following 48 pixel by 48 pixel versions of the icon:</para> <itemizedlist> <listitem> <para>Regular icon</para> </listitem> <listitem> <para>Low contrast icon</para> </listitem> <listitem> <para>High contrast icon</para> </listitem> <listitem> <para>Inverse high contrast icon</para> </listitem> </itemizedlist> <para>If possible, create 16 pixel by 16 pixel versions of the each of the icons above also, for themes that do not require large print.</para> <para>Install the icons to the image files location that is specified for the theme in <xref linkend="themes-3"/> or <xref linkend="themes-5"/>. For example, to add icons to the HighContrastLargePrint theme, add the icons to the <filename>/usr/share/themes/HighContrastLargePrint/pixmaps</filename> directory. Add references to the icons to the relevant theme files. For example, to add icons to the HighContrastLargePrint theme, add references to the icons to the <filename>/usr/share/themes/HighContrastLargePrint/gtk-2.0/gtkrc</filename> file. Modify the <filename>gtkrc</filename> file for the theme to associate the icon with a GTK stock icon identifier.</para> <para>For more information on how to create icons for application launchers and for panels, see <ulink url="http://www.freedesktop.org/Standards/icon-theme-spec">http://www.freedesktop.org/Standards/icon-theme-spec</ulink>.</para> </sect1> <sect1 id="themes-15"> <title>To Create a Custom Controls Option</title> <indexterm> <primary>themes</primary> <secondary>controls options</secondary> <tertiary>creating custom</tertiary> </indexterm> <para>If the options for the controls setting are not suitable for the needs of your users, you can create a custom controls option. To create a custom controls option, perform the following steps:</para> <orderedlist> <listitem> <para>Create a directory structure for the option in the <filename>/usr/share/themes</filename> directory. Use the same directory structure that other options use. For example, to create an option that is called SmallPrint, create the following directories:</para> <itemizedlist> <listitem> <para> <filename>/usr/share/themes/SmallPrint</filename> </para> </listitem> <listitem> <para> <filename>/usr/share/themes/SmallPrint/gtk-2.0</filename> </para> </listitem> </itemizedlist> </listitem> <listitem> <para>Locate the <filename>gtkrc</filename> file that is closest to meeting the needs of your users. Copy the file to the <filename>gtk-2.0</filename> directory of your new option.</para> </listitem> <listitem> <para>Open the <filename>gtkrc</filename> file in a text editor, and modify the attributes of the interface elements as required. </para> </listitem> <listitem> <para>If the new option includes images, install the images for the new option in the <filename>pixmaps</filename> directory of your new option. If the new option uses images from another option, you do not need to create copies of the images for the new option. Instead, ensure that the reference to the images in the <literal>pixmap_path</literal> entry in the <filename>gtkrc</filename> file is correct.</para> </listitem> </orderedlist> <para>Users can now choose the new option for the controls setting.</para> <para>For more information on <filename>gtkrc</filename> files, see <ulink url="http://developer.gnome.org/doc/API/2.0/gtk/index.html">http://developer.gnome.org/doc/API/2.0/gtk/index.html</ulink>.</para> </sect1> </chapter>
