IXRScaleTransform::GetScaleY (Windows Embedded CE 6.0)
1/6/2010
This method retrieves the factor by which to scale the UI object along the y-axis.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetScaleY(
float* pScaleY
) = 0;
Parameters
- pScaleY
[out] Pointer to a float value that indicates the scale factor along the y-axis.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
The default value is 1, which indicates no scaling along the y-axis. When pScaleY is between 0 and 1, it decreases the length of the scaled object. When pScaleY is greater than 1, it increases the length of the scaled object.
When pScaleY is a negative value, it flips the scaled object vertically. When pScaleY is between 0 and -1, it flips the scaled object and decreases its length. When pScaleY is less than -1, it flips the object and increases its length. A value of -1 flips the scaled object but does not change its vertical 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.
