Parameters

Viewer

The DicomViewer object which holds the Image that measurement is being taken on

Index

The Image index of the image that measurement is being taken on

Return Value

Where pixel dimensions for the whole image are present within the image data, these are used to scale the area appropriately, and multiple region calibration areas (e.g. in U/S images) are supported. The units used (which for uncalibrated data may simply be pixels) is returned by ROIDistanceUnits (for this property, they should be interpreted as square units of course)

This method may only be used for DicomLabels of type Rectangle, Ellipse, Polygon or Bitmap.

Target Platforms: .NET CLR 4.8 or higher
