A glyph is the visual representation of one or more characters. Many different glyphs can be used to represent a single character or combination of characters. <code>GlyphMetrics</code> instances are produced by <A HREF="../../../java/awt/Font.html"><CODE>Font</CODE></A> and are applicable to a specific glyph in a particular <code>Font</code>. <p> Glyphs are either STANDARD, LIGATURE, COMBINING, or COMPONENT. <ul> <li>STANDARD glyphs are commonly used to represent single characters. <li>LIGATURE glyphs are used to represent sequences of characters. <li>COMPONENT glyphs in a <A HREF="../../../java/awt/font/GlyphVector.html"><CODE>GlyphVector</CODE></A> do not correspond to a particular character in a text model. Instead, COMPONENT glyphs are added for typographical reasons, such as Arabic justification. <li>COMBINING glyphs embellish STANDARD or LIGATURE glyphs, such as accent marks. Carets do not appear before COMBINING glyphs. </ul> <p> Other metrics available through <code>GlyphMetrics</code> are the advance, bounds, and left and right side bearings. <p> The advance of a glyph is the distance from the glyph's origin to the origin of the next glyph. Note that, in a <code>GlyphVector</code>, the distance from a glyph to its following glyph might not be the glyph's advance. <p> The bounds is the smallest rectangle that completely contains the visible portion of the glyph. The bounds rectangle is relative to the glyph's origin. The left-side bearing is the distance from the glyph origin to the left of its bounds rectangle. If the left-side bearing is negative, part of the glyph is drawn to the left of its origin. The right-side bearing is the distance from the right side of the bounds rectangle to the next glyph origin (the origin plus the advance). If negative, part of the glyph is drawn to the right of the next glyph's origin. <p> Although instances of <code>GlyphMetrics</code> can be directly constructed, they are almost always obtained from a <code>GlyphVector</code>. Once constructed, <code>GlyphMetrics</code> objects are immutable. <p> <strong>Example</strong>:<p> Querying a <code>Font</code> for glyph information <blockquote><pre> Font font = ...; int glyphIndex = ...; GlyphMetrics metrics = GlyphVector.getGlyphMetrics(glyphIndex); int isStandard = metrics.isStandard(); float glyphAdvance = metrics.getAdvance(); </blockquote></pre><P><DL><DT><B>See Also:
