LineMetrics JDK 1.6)

Description

publicabstract abstract class LineMetrics

The LineMetrics class allows access to the metrics needed to layout characters along a line and to layout of a set of lines.

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 LineMetrics.getNumChars().

Methods

Hide/Show inherited methods

publicabstract float getAscent ()

Returns the ascent of the text.

publicabstract int getBaselineIndex ()

Returns the baseline index of the text.

publicabstract float getBaselineOffsets ()

Returns the baseline offsets of the text, relative to the baseline of the text.

Returns the baseline offsets of the text,
relative to the baseline of the text. The
offsets are indexed by baseline index. For
example, if the baseline index is
CENTER_BASELINE then
offsets[HANGING_BASELINE] is usually
negative, offsets[CENTER_BASELINE]
is zero, and offsets[ROMAN_BASELINE]
is usually positive.
Returns: the baseline offsets of the text.

publicabstract float getDescent ()

Returns the descent of the text.

publicabstract float getHeight ()

Returns the height of the text.

publicabstract float getLeading ()

Returns the leading of the text.

publicabstract int getNumChars ()

Returns the number of characters (char values) in the text whose metrics are encapsulated by this LineMetrics object.

Returns the number of characters (char values) in the text whose
metrics are encapsulated by this LineMetrics
object.
Returns: the number of characters (char values) in the text with which this LineMetrics was created.

publicabstract float getStrikethroughOffset ()

Returns the position of the strike-through line relative to the baseline.

publicabstract float getStrikethroughThickness ()

Returns the thickness of the strike-through line.

publicabstract float getUnderlineOffset ()

Returns the position of the underline relative to the baseline.

publicabstract float getUnderlineThickness ()

Returns the thickness of the underline.
