HitTest Method (original) (raw)

Syntax

Parameters

hitTestBuffer

The threshold buffer value, in pixels.

Return Value

true if the test point intersects with the object; otherwise, false.

Remarks

point should be in physical coordinates.

hitTestBuffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 pixels around the test point will be used to perform the hit-testing.

By default, an annotation object will return true if hit-testing was satisfied. Derived objects can override this method to fine-tune the return value.
