GetAutoScaleData() Method

Summary

Returns a DicomAutoScaleData object that specifies if the DICOM pixel data has been autoscaled, and if so, the autoscale slope and autoscale intercept.

Syntax

C++/CLI

public DicomAutoScaleData GetAutoScaleData()

public:  
   DicomAutoScaleData^ GetAutoScaleData()

Return Value

A DicomAutoScaleData object that specifies if the DICOM pixel data has been autoscaled, and if so, the autoscale slope and autoscale intercept.

Remarks
