AngleRange Property

Summary

This value indicates the maximum angle of deskew, in hundredths of degrees.

Syntax

C++/CLI

Python

public int AngleRange { get; set; }

public:  
   property Int32 AngleRange 
   { 
      Int32 get() 
      void set(Int32 value) 
   }

AngleRange # get and set (DeskewDetectionData)

Property Value

Value that indicates the maximum angle of deskew, in hundredths of degrees. Possible values range from 0 to 4500.
