GetRotateImagePerspectiveAngle(Int32) Method

Summary

Gets the rotation angle for the image in the specified sub-cell.

Syntax

C++

public int GetRotateImagePerspectiveAngle(  
   int subCellIndex 
)

Public Overloads Function GetRotateImagePerspectiveAngle( _ 
   ByVal subCellIndex As Integer _ 
) As Integer

public: 
int GetRotateImagePerspectiveAngle(  
   int subCellIndex 
)

Parameters

subCellIndex
The zero-based index of the sub-cell that has the image for which the rotation angle is being retrieved. If the cell contains only 1 image, set this parameter to 0. Pass -2 to retrieve the rotation angle of the selected sub-cell.

Return Value

The image rotation angle.

Remarks

In order to get the correct value from this function, you should rotate the images in the medical viewer control using the RotateImagePerspective method.
