public double[] GetProjectionValues()

public double[] GetProjectionValues()

Public Function GetProjectionValues As Double()

Public Function GetProjectionValues As Double()

public:
array<double>^ GetProjectionValues()

public:
array<double>^ GetProjectionValues()

Return Value

Type: Double

Remarks

Projected image values. These are normalized to the range 0 -> 255 and account for any clipping.

You can use the values in this array to construct a graphical representation of the projected image.
