BitsPerPixel Property

Summary
Gets the number of bits per pixel of this RasterImage.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public int BitsPerPixel { get; } 
@property (nonatomic, assign, readonly) NSInteger bitsPerPixel 
public int getBitsPerPixel(); 
public: 
property int BitsPerPixel { 
   int get(); 
} 
BitsPerPixel # get  (RasterImage) 

Property Value

Number of bits per pixel of this RasterImage.

Remarks

The RasterImage object supports image data of 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32, 48 and 64 bits per pixel

A 16-bpp image may be color or grayscale. If you are working with a 16-bit grayscale image, then use RasterByteOrder.Gray when creating the image. By default, the Order for a 16-bit image will be set to RasterByteOrder.Bgr.
