IXRBrush::SetOpacity (Windows Embedded CE 6.0)
1/6/2010
This method sets the degree of opacity of this brush object.
Syntax
virtual HRESULT STDMETHODCALLTYPE SetOpacity(
float Opacity
) = 0;
Parameters
- Opacity
[in] A float value that indicates the new degree of opacity of this brush object. This value can range from 0 to 1.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
An Opacity value of 0 indicates that the brush is completely transparent, whereas a value of 1 indicates that the brush is completely opaque. A value of 0.5 indicates that the brush is 50% opaque, a value of 0.725 indicates that the brush is 72.5% opaque, and so on. Values less than 0 are treated as 0, and values greater than 1 are treated as 1.
If Opacity is 0, the brush is still hit testable. Only a true null brush is not hit testable. To remove hit testing against an IXRUIElement where this brush is applied, call IXRUIElement::SetIsHitTestVisible on that IXRUIElement object.
