Specifies the type of DicomAutoScaleData returned with a call to GetAutoScaleData.
public enum DicomAutoScaleDataFlags
public:
enum class DicomAutoScaleDataFlags sealed
Value | Member | Description |
---|---|---|
0 | None | None |
1 | AutoScaleSlopeIntercept | DicomAutoScaleData contains the autoscale slope and autoscale intercept if the DICOM pixel data has been autoscaled. |
2 | InverseModalityLut | DicomAutoScaleData defines a linear transformation that is the inverse of the linear transformation specified in the DicomDataSet |
For more information, see the GetAutoScaleData(DicomAutoScaleDataFlags) method.
