BytesPerLine Property

Summary
Gets the number of bytes per scanline for the image data.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public int BytesPerLine { get; } 
@property (nonatomic, assign, readonly) NSInteger bytesPerLine; 
public int getBytesPerLine() 
public: 
property int BytesPerLine { 
   int get(); 
} 
BytesPerLine # get  (CodecsImageInfo) 

Property Value

the number of bytes per scanline for the image data.. The default value is 0.

Remarks

The BytesPerLine is rounded upward to the nearest multiple of four.
