cairo:in-stroke (cr x y)

cr -- a cairo:context-t instance
x -- a number for the x coordinate of the point to test
y -- a number for the y coordinate of the point to test

True if the point is inside, or false if outside.

Tests whether the given point is inside the area that would be affected by a cairo:stroke operation given the current path and stroking parameters. Surface dimensions and clipping are not taken into account.

See the cairo:stroke, cairo:line-width, cairo:line-join, cairo:line-cap, cairo:dash, and cairo:stroke-preserve functions. The numbers for the arguments are coerced to double floats before being passed to the foreign C function.
