SetAutoFixImageResolutionOptions Method

Summary

Sets the automatic resolution conversion options used by LEADTOOLS to automatically convert the resolution of digital photos.

Syntax

C++/CLI

Python

public static void SetAutoFixImageResolutionOptions( 
   AutoFixImageResolutionOptions value 
)

public:  
   static void SetAutoFixImageResolutionOptions( 
      AutoFixImageResolutionOptions^ value 
   )

def SetAutoFixImageResolutionOptions(self,value):

Parameters

value

The automatic resolution conversion options used by LEADTOOLS to automatically convert the resolution of digital photos.

Remarks

The options set by this method are global (valid for all the threads).

Use RasterDefaults.GetAutoFixImageResolutionOptions.
