java.lang.Object | +--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
Font
take some text as an argument
and return a LineMetrics
object describing the
metrics of the initial number of characters in that text, as
returned by getNumChars()
.
