.SH STRUCTURES
|

The
|
|

|
|
structure contains:

} XFontSetExtents;
|

.De
|
|
.LP
|
|
The
|
|
.ZN XRectangle
|
|
structures used to return font set metrics are the usual Xlib screen-oriented
|
|
rectangles
|
|
with x, y giving the upper left corner, and width and height always positive.
|
|
.LP
|
|
The max_ink_extent member gives the maximum extent, over all drawable characters, of
|
|
the rectangles that bound the character glyph image drawn in the
|
|
foreground color, relative to a constant origin.
|
|
See
|
|
.ZN XmbTextExtents
|
|
and
|
|
.ZN XwcTextExtents
|
|
for detailed semantics.
|
|
.LP
|
|
The max_logical_extent member gives the maximum extent,
|
|
over all drawable characters, of the rectangles
|
|
that specify minimum spacing to other graphical features,
|
|
relative to a constant origin.
|
|
Other graphical features drawn by the client, for example,
|
|
a border surrounding the text, should not intersect this rectangle.
|
|
The max_logical_extent member should be used to compute minimum
|
|
interline spacing and the minimum area that must be allowed
|
|
in a text field to draw a given number of arbitrary characters.
|
|
.LP
|
|
Due to context-dependent rendering,
|
|
appending a given character to a string may change
|
|
the string's extent by an amount other than that character's
|
|
individual extent.
