Example 14 with GlyphVector

use of java.awt.font.GlyphVector in project jdk8u_jdk by JetBrains.

the class Font method getStringBounds.

     * text, use the {@link TextLayout#getBounds() getBounds} method of
     * <code>TextLayout</code>.
     * <p>Note: The returned bounds is in baseline-relative coordinates
     * (see {@link java.awt.Font class notes}).
