IXRLinearGradientBrush::SetEndPoint (Compact 2013)

3/28/2014

This method sets the two-dimensional coordinates of the ending point for this linear gradient.

Syntax

virtual HRESULT STDMETHODCALLTYPE SetEndPoint(
    XRPoint* pEndPoint
) = 0;

Parameters

  • pEndPoint
    [in] Pointer to an XRPoint structure that specifies the x-y coordinates of the gradient endpoint.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

An IXRLinearGradientBrush paints a gradient along a line. The line's starting points and endpoints are defined by IXRLinearGradientBrush::SetStartPoint and SetEndPoint in the IXRLinearGradientBrush class.

The default linear gradient is diagonal, and the default mode for the gradient coordinate system is XRBrushMappingMode_RelativeToBoundingBox. When the inherited method IXRGradientBrush::GetMappingMode returns the mapping mode XRBrushMappingMode_RelativeToBoundingBox, pEndPoint is a logical point, where values between 0 and 1 are mapped against the total size of the resulting bounding box. By default, the pEndPoint value of a linear gradient is an XRPoint value of (1,1), the lower-right corner of the area being painted. The colors in the resulting gradient are interpolated and applied along vectors that parallel this diagonal axis.
