Parameters

Viewer: The Viewer from which the Image is drawn

Return Value

This property may not be used for DicomLabels of type Bitmap.

The length is the length of the entire circumference of the label.

Where pixel dimensions for the whole image are present within the image data, these are used to scale the length appropriately. Multiple region calibration areas (e.g. in U/S images) are fully supported.

The units used (which for uncalibrated data may simply be pixels) is returned by ROIDistanceUnits.

Requirements

Target Platforms: .NET CLR 4.8 or higher
