IsBigTiff Property

Summary
Determines whether the image file is BigTIFF.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public bool IsBigTiff {get;} 
@property (nonatomic, assign, readonly) BOOL isBigTiff; 
public boolean isBigTiff() 
public: 
property bool IsBigTiff { 
   bool get(); 
} 
IsBigTiff # get  (CodecsTiffImageInfo) 

Property Value

true if the file is BigTIFF, false if the file is TIFF. The default value is false.

Remarks

Use this to determine whether the file is BigTIFF.
