Class FontMetrics
A FontMetrics structure holds the overall metric information for a font
(possibly restricted to a script).
FontMetrics
protected FontMetrics(Handle handle)
getApproximateCharWidth
public int getApproximateCharWidth()
Gets the approximate character width for the font metrics. This is
merely a representative value useful, for example, for determining
the initial size for a window. Actual characters in text will be
wider and narrower than this.
getApproximateDigitWidth
public int getApproximateDigitWidth()
Gets the approximate digit width for the font metrics. This is merely
a representative value useful, for example, for determining the
initial size for a window. Actual digits in text can be wider and
narrower than this.
getAscent
public int getAscent()
Gets the ascent from the font metrics. The ascent is the distance
from the baseline to the logical top of a line of text. (The
logical top may be above or below the top of the actual drawn ink.
It is necessary to lay out the text to figure where the ink will be.)
getDescent
public int getDescent()
Gets the descent from the font metrics. The descent is the distance
from the baseline to the logical bottom of a line of text. (The
logical bottom may be above or below the bottom of the actual drawn
ink. It is necessary to lay out the text to figure where the ink will
be.)
