IXRScaleTransform::GetScaleX (Windows Embedded CE 6.0)
1/6/2010
This method retrieves the factor by which to scale the UI object along the x-axis.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetScaleX(
float* pScaleX
) = 0;
Parameters
- pScaleX
[out] Pointer to a float value that indicates the scale factor along the x-axis.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
The default value is 1, which indicates no scaling along the x-axis. When pScaleX is between 0 and 1, it decreases the width of the scaled object. When pScaleX is greater than 1, it increases the width of the scaled object.
When pScaleX is a negative value, it flips the scaled object horizontally. When pScaleX is between 0 and -1, it flips the scaled object and decreases its width. When pScaleX is less than -1, it flips the object and increases its width. A value of -1 flips the scaled object but does not change its horizontal size.
You can offset the local origin point (0,0) for a UI element on an IXRCanvas container object by setting the attached properties Canvas.Left and Canvas.Top. However, this is not considered a transformation; the UI object keeps its own local origin point for transformation purposes.
