IManipulationProcessor::MinimumScaleRotateRadius property

  • Article

Specifies how large the distance contacts on a scale or rotate gesture need to be to trigger manipulation.

This property is read/write.

Syntax

HRESULT put_MinimumScaleRotateRadius(
  [in]  FLOAT MinimumScaleRotateRadius
);

HRESULT get_MinimumScaleRotateRadius(
  [out] FLOAT *MinimumScaleRotateRadius
);

Property value

Specifies the minimum distance between contacts to trigger scale or rotate gestures.

Remarks

Note

This property is set in centipixels (100ths of a pixel).

 

Setting this value will make the manipulation processor ignore gestures that have too small of a radius. This is useful if you want to prevent a user from manipulating an object to too small of a radius. For example, if you are using a manipulation processor with a circle and want the ensure that it maintains a radius greater than 100 pixels, you would set this value to 10000.

Examples

pManip->put_MinimumScaleRotateRadius(4000.0f);
