Thread safety: This property is not thread-safe.
Syntax
public System.Int32 TouchRadius { get; set; }Property Value
Type: System.Int32
Default: 0
A value greater than zero will override the touch radius reported by the hardware.
Default: 0
A value greater than zero will override the touch radius reported by the hardware.
Remarks
The default behavior of the StandardTouchTool is to use the touch point radius as reported by the hardware in each touch event and in most cases this works well. However, some hardware can be too sensitive or inaccurate and some hardware does not report touch point sizes at all, typically hardware that use a stylus for touch input, when this is the case you can use this property to set an explicit and fixed touch radius.
Note
In cases where the hardware consistently reports touch points that are too small or too large it is usually much better to modify the TouchRadiusScaleFactor instead of setting an explicit touch radius.
