Relationships between adjacent glyphs in sequence are solely used to determine the placement of the glyphs in the visual coordinate space. <p> Instances of <code>GlyphVector</code> are created by a <A HREF="../../../java/awt/Font.html"><CODE>Font</CODE></A>. <p> In a text processing application that can cache intermediate representations of text, creation and subsequent caching of a <code>GlyphVector</code> for use during rendering is the fastest method to present the visual representation of characters to a user. <p> A <code>GlyphVector</code> is associated with exactly one <code>Font</code>, and can provide data useful only in relation to this <code>Font</code>. In addition, metrics obtained from a <code>GlyphVector</code> are not generally geometrically scaleable since the pixelization and spacing are dependent on grid-fitting algorithms within a <code>Font</code>. To facilitate accurate measurement of a <code>GlyphVector</code> and its component glyphs, you must specify a scaling transform, anti-alias mode, and fractional metrics mode when creating the <code>GlyphVector</code>. These characteristics can be derived from the destination device. <p> For each glyph in the <code>GlyphVector</code>, you can obtain: <ul> <li>the position of the glyph <li>the transform associated with the glyph <li>the metrics of the glyph in the context of the <code>GlyphVector</code>. The metrics of the glyph may be different under different transforms, application specified rendering hints, and the specific instance of the glyph within the <code>GlyphVector</code>. </ul> <p> Altering the data used to create the <code>GlyphVector</code> does not alter the state of the <code>GlyphVector</code>. <p> Methods are provided to create new <code>GlyphVector</code> objects which are the result of editing operations on the <code>GlyphVector</code>, such as glyph insertion and deletion. These methods are most appropriate for applications that are forming combinations such as ligatures from existing glyphs or are breaking such combinations into their component parts for visual presentation. <p> Methods are provided to create new <code>GlyphVector</code> objects that are the result of specifying new positions for the glyphs within the <code>GlyphVector</code>. These methods are most appropriate for applications that are performing justification operations for the presentation of the glyphs. <p> Methods are provided to return both the visual and logical bounds of the entire <code>GlyphVector</code> or of individual glyphs within the <code>GlyphVector</code>. <p> Methods are provided to return a <A HREF="../../../java/awt/Shape.html"><CODE>Shape</CODE></A> for the <code>GlyphVector</code>, and for individual glyphs within the <code>GlyphVector</code>.<P><DL><DT><B>See Also: </B><DD><A
