Description Usage Arguments Details Value Author(s)
Computes a bounding box in user coordinates covering the area that
would be affected, (the "inked" area), by a cairoStroke
operation given the current path and stroke parameters.
If the current path is empty, returns an empty rectangle ((0,0), (0,0)).
Surface dimensions and clipping are not taken into account.

Note that if the line width is set to exactly zero, then
cairoStrokeExtents
will return an empty rectangle. Contrast with
cairoPathExtents
which can be used to compute the nonempty
bounds as the line width approaches zero.
Note that cairoStrokeExtents
must necessarily do more work to
compute the precise inked areas in light of the stroke parameters,
so cairoPathExtents
may be more desirable for sake of
performance if noninked path extents are desired.
