IManipulationProcessor::get_MinimumScaleRotateRadius method (manipulations.h)

Article
2024-02-22

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 get_MinimumScaleRotateRadius(
  FLOAT *minRadius
);

Parameters

minRadius

Return value

None

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);
