| Constructor Summary | |
| public | X11FontMetrics(Font font)
Calculate the metrics from the given WServer and font. |
| ascent | | int ascent(Code) | | The standard ascent of the font. This is the logical height
above the baseline for the Alphanumeric characters and should
be used for determining line spacing. Note, however, that some
characters in the font may extend above this height.
|
| descent | | int descent(Code) | | The standard descent of the font. This is the logical height
below the baseline for the Alphanumeric characters and should
be used for determining line spacing. Note, however, that some
characters in the font may extend below this height.
|
| height | | int height(Code) | | The standard height of a line of text in this font. This is
the distance between the baseline of adjacent lines of text.
It is the sum of the ascent+descent+leading. There is no
guarantee that lines of text spaced at this distance will be
disjoint; such lines may overlap if some characters overshoot
the standard ascent and descent metrics.
|
| leading | | int leading(Code) | | The standard leading for the font. This is the logical amount
of space to be reserved between the descent of one line of text
and the ascent of the next line. The height metric is calculated
to include this extra space.
|
| maxAdvance | | int maxAdvance(Code) | | The maximum advance width of any character in this font.
|
| maxAscent | | int maxAscent(Code) | | The maximum ascent for all characters in this font. No character
will extend further above the baseline than this metric.
|
| maxDescent | | int maxDescent(Code) | | The maximum descent for all characters in this font. No character
will descend further below the baseline than this metric.
|
| maxHeight | | int maxHeight(Code) | | The maximum possible height of a line of text in this font.
Adjacent lines of text spaced this distance apart will be
guaranteed not to overlap. Note, however, that many paragraphs
that contain ordinary alphanumeric text may look too widely
spaced if this metric is used to determine line spacing. The
height field should be preferred unless the text in a given
line contains particularly tall characters.
|
| widths | | int widths(Code) | | The widths of the first 256 characters.
