.SH DESCRIPTION
|
|
The
|
|
.ZN XmbTextExtents
|
|
and
|
|
.ZN XwcTextExtents
|
|
functions set the components of the specified overall_ink_return and
|
|
overall_logical_return
|
|
arguments to the overall bounding box of the string's image,
|
|
and a logical bounding box for spacing purposes, respectively.
|
|
They return the value returned by
|
|
.ZN XmbTextEscapement
|
|
or
|
|
.ZN XwcTextEscapement .
|
|
These metrics are relative to the drawing origin of the string,
|
|
using the fonts loaded for the specified font set.
|
|
.LP
|
|
If the overall_ink_return argument is non-NULL,
|
|
it is set to the bounding box of the string's character ink.
|
|
Note that the overall_ink_return for a non-descending horizontally drawn
|
|
Latin character is conventionally entirely above the baseline, that is,
|
|
overall_ink_return.height <= -overall_ink_return.y.
|
|
The overall_ink_return for a nonkerned character
|
|
is entirely at and to the right of the origin, that is,
|
|
overall_ink_return.x >= 0.
|
|
A character consisting of a single pixel at the origin
|
|
would set overall_ink_return fields y = 0, x = 0, width = 1, height = 1.
|
|
.LP
|
|
If the overall_logical_return argument is non-NULL,
|
|
it is set to the bounding box which provides minimum spacing
|
|
to other graphical features for the string.
|
|
Other graphical features, for example, a border surrounding the text,
|
|
should not intersect this rectangle.
|
|
.LP
|
|
When the
|
|
.ZN XFontSet
|
|
has missing charsets,
|
|
metrics for each unavailable character are taken
|
|
from the default string returned by
|
|
.ZN XCreateFontSet
|
|
so that the metrics represent the text as it will actually be drawn.
|
|
The behavior for an invalid codepoint is undefined.
