<para>
|
|
Computes a bounding box in user coordinates covering the area that would be affected,
|
|
(the “inked” area), by a <methodname>CairoContext::fill</methodname> operation given the
|
|
current path and fill parameters. If the current path is empty,
|
|
returns an empty rectangle (0,0,0,0). Surface dimensions and clipping are not taken into account.
|
|
</para>
|
|
<para>
|
|
Contrast with <methodname>CairoContext::pathExtents</methodname>, which is similar, but returns
|
|
non-zero extents for some paths with no inked area, (such as a simple line segment).
|
|
</para>
|
|
<para>
|
|
Note that <methodname>CairoContext::fillExtents</methodname> must necessarily do more work to
|
|
compute the precise inked areas in light of the fill rule, so
|
|
<methodname>CairoContext::pathExtents</methodname> may be more desirable for sake of
|
|
performance if the non-inked path extents are desired.
