Examples of LineMetrics

ae.java.awt.font.LineMetrics
The LineMetrics class allows access to the metrics needed to layout characters along a line and to layout of a set of lines. A LineMetrics object encapsulates the measurement information associated with a run of text.
Fonts can have different metrics for different ranges of characters. The getLineMetrics methods of {@link ae.java.awt.Font Font} take some text as an argumentand return a LineMetrics object describing the metrics of the initial number of characters in that text, as returned by {@link #getNumChars}.
