IgnoreViewPerspective Property

Summary

Gets or sets a value that indicates whether to ignore the view perspective stored in the file.

Syntax

Objective-C

C++/CLI

Java

Python

public bool IgnoreViewPerspective { get; set; }

@property (nonatomic, assign) BOOL ignoreViewPerspective;

public boolean getIgnoreViewPerspective() 
public void setIgnoreViewPerspective(boolean value)

public: 
property bool IgnoreViewPerspective { 
   bool get(); 
   void set (    bool ); 
}

IgnoreViewPerspective # get and set (CodecsTiffLoadOptions)

Property Value

Value	Description
true	To load the file as RasterViewPerspective.TopLeft.
false	To not load the file as RasterViewPerspective.TopLeft. The default value is false.

Remarks

If you are loading a TIFF or Exif file that looks rotated or flipped, try setting this property before loading the file.
