GetNewViewPerspective(RasterViewPerspective,Double[],PlaneOrientation) Method

public static RasterViewPerspective GetNewViewPerspective( 
   RasterViewPerspective viewPerspectiveOriginal,
   double[] imageOrientationVectors,
   PlaneOrientation po
)

public:
static RasterViewPerspective GetNewViewPerspective( 
   RasterViewPerspective viewPerspectiveOriginal,
   array<double>^ imageOrientationVectors,
   PlaneOrientation^ po
)

'Declaration

Public Overloads Shared Function GetNewViewPerspective( _
   ByVal viewPerspectiveOriginal As RasterViewPerspective, _
   ByVal imageOrientationVectors() As Double, _
   ByVal po As PlaneOrientation _
) As RasterViewPerspective

'Usage

Dim viewPerspectiveOriginal As RasterViewPerspective
Dim imageOrientationVectors() As Double
Dim po As PlaneOrientation
Dim value As RasterViewPerspective
 
value = DicomExtensions.GetNewViewPerspective(viewPerspectiveOriginal, imageOrientationVectors, po)

Parameters

viewPerspectiveOriginal: The input RasterViewPerspective to which the PlaneOrientation will be applied.
imageOrientationVectors: The row and column orientation vectors (or direction cosine vectors) that apply to viewPerspectiveOriginal
po: A PlaneOrientation that is applied to the original RasterViewPerspective

Return Value

The new RasterViewPerspective that results from having the PlaneOrientation applied.

The input view perspective is define by two values: the original RasterViewPerspective (viewPerspectiveOriginal), and a row and column orientation vector (imageOrientationVectors). This method returns the new RasterViewPerspective that results from applying a PlaneOrientation to the input view perspective.

This example does the following:

Creates a coronal PlaneOrientation that corresponds to a horizontal flip
Defines orientation vectors that corresponds to a coronal slice
Applies the above to a view perspective, and returns the resulting view perspective
