</PRE>
<P>
A simple abstraction of platform fonts and library fonts that enables the library to use more elaborate fonts unsupported by a specific device. This abstraction also supports bitmap fonts using an Ant task (more details about the unifier are explained in the javadoc overview document). <p>A bitmap font can be created manually but that is tedious, normally you would use the Ant task as illustrated bellow to produce a resource file containing the supported bitmap font. For further detail read the overview document and <A HREF="../../../com/sun/lwuit/util/Resources.html" title="class in com.sun.lwuit.util"><CODE>Resources</CODE></A>.<pre><target name="pre-init"> <taskdef classpath="ImageUnifier.jar" classname="com.sun.jwt.resource.Builder" name="build" /> <build dest="src/font.res"> <font src="images/arial.ttf" bold="true" italic="true" size="11" /> <font logicalName="Dialog" /> </build></target></pre> <p>The following attributes can be expressed for a font ant task: <ul> <li>name - name for the font to load from the resource file (optional: defaults to logical name or file name). <li>charset - defaults to the English alphabet, numbers and common signs. Should contain a list of all characters that should be supported by a font. E.g. if a font would always be used for uppercase letters then it would save space to define the charset as: <code>"ABCDEFGHIJKLMNOPQRSTUVWXYZ" </code> <li>src - font file in the case of using a file, defaults to TrueType font <li>size - floating point size of the font <li>bold - defaults to false indicates if the font should be bold <li>italic - defaults to false indicates if the font should be italic <li>trueType - defaults to true, relevant only when src is used. If set to false type 1 fonts are assumed. <li>antiAliasing - defaults to true otherwise fonts will be aliased <li>logicalName - logical name of the font as specified by java.awt.Font in Java SE: <code>Dialog, DialogInput, Monospaced, Serif, or SansSerif </code> </ul>
