Visual Basic
C#
Delphi
JScript
C++/CLI

'Declaration
 
Public Function MeasureSkew() As System.Double

'Usage
 
Dim instance As CiTools
Dim value As System.Double
 
value = instance.MeasureSkew()

public System.double MeasureSkew()

public function MeasureSkew(): System.Double;

public function MeasureSkew() : System.double;

public:
System.double MeasureSkew();

Return Value

The returned value is in the range from -45 degrees to 45 degrees. If the value is negative, the image is skewed counterclockwise.

Measures image or zone skew relative to the nearest vertical or horizontal axis.
rConfidence property contains confidence level in percents.

C#
VB.NET

void MeasureSkewRotation(string imageFile)
{
    // Open image file
    CiServer ci = Inlite.ClearImageNet.Server.GetThreadServer();
    CiTools Tools = ci.CreateTools();
    Tools.Image.Open(imageFile, 1);
    // Do processing
    double skew; EPageRotation rot;
    skew = Tools.MeasureSkew();
    Console.WriteLine("Skew= " + skew + "   Confidence= " + Tools.rConfidence + "%");
    rot = Tools.MeasureRotation();
    Console.WriteLine("Rotation= " + rot.ToString() + "   Confidence=" + Tools.rConfidence + "%");
}

Sub MeasureSkewRotation(imageFile As String)
    ' Open image file

    Dim Tools As CiTools = ci.CreateTools()
