+<p>The term <i>scalability</i> refers to the ability of an application
+UI to function as designed in mobile devices with different screen resolutions
+or orientations. For example, in the figure below, the UI scales to fit both
+portrait and landscape orientations.</p>
+<fig id="GUID-573B32DC-5C53-47B2-8239-AA038E945E81"><title>Scaling</title><image href="GUID-5F9E2762-855A-4DE6-A11B-A5F0D51E19D9_d0e42268_href.png"></image></fig>
+<p>When you enable scaling in your application, you allow your application
+to support the different display sizes, resolutions, and layouts for different
+devices based on the Symbian platform. The Symbian platform provides APIs
+and other support to enable scaling in applications. Some scaling issues are
+handled by the application framework if support is enabled, while other issues
+need to be handled by the application. The details of what can be handled
+where depend on the nature of your UI architecture. A general rule of thumb
+is that the greater the degree of customization in your application, the more
+you need to handle scalability issues in the application.</p>
+<p>You are not required to enable scaling in your applications, although
+it is recommended as it enhances usability for mobile device users.</p>
+<p>The following issues should be kept in mind when enabling your application
+for scaling:</p>
+<ul>
+<li><p>Layout information should not be hard-coded.</p>
+<itemgroup>
+<p> The Symbian platform provides the <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classAknLayoutUtils.html" format="application/java-archive"><parmname>AknLayoutUtils</parmname></xref> class
+for building layouts from resource files.</p>
+<p>Note that you also need to <xref href="GUID-DD15F24B-0786-4531-A6C5-A5E70EBE2732.dita">override <parmname>CCoeControl::HandleResourceChange</parmname> and <parmname>CEikAppUi::HandleResourceChangeL</parmname></xref> in your
+application to draw your application again in the event that the orientation
+of the display changes.</p>
+</itemgroup>
+</li>
+<li><p>Scalable fonts should be used.</p>
+<itemgroup>
+<p>The Symbian platform provides methods in the <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classAknLayoutUtils.html" format="application/java-archive"><parmname>AknLayoutUtils</parmname></xref> for
+using logical fonts from an enumeration in the avkon.hrh file.</p>
+</itemgroup>
+</li>
+<li><p>Scalable icons should be used.</p>
+<itemgroup>
+<p>Scalable icons are based on SVG Tiny (SVG-T) format <xref href="GUID-D76B1001-BAF5-4557-A07E-61065523ECBE.dita">graphics</xref>.</p>
