function Leadtools.Annotations.Rendering.AnnSvgThumbStyle.renderHitTest( location , testPoint , hitTestBuffer , mapper )
| Parameter | Type | Description |
|---|---|---|
| location | LeadPointD | The location of the thumb to test in container coordinates. |
| testPoint | LeadPointD | The point to test in container coordinates. |
| hitTestBuffer | double | The hit test buffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if the buffer value is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing. This value is in container coordinates. |
| mapper | AnnContainerMapper | The mapper object to use for converting coordinates. Must not be null. |
| Type | Description |
|---|---|
| boolean | true if the specified test point is over the thumb, otherwise; false. |
The automation framework will call RenderHitTest repeatedly to determine if a user input location is over a thumb. For example, to determine if the framework should start dragging a side of a selected object or to start rotating it.
