This property sets the YCrCb subsampling ratios when saving an image in JPEG format.

[Visual Basic] Public Property JpegSubsampling As Newtone.ImageKit.JpegSubsamplingKind
[C#] public Newtone.ImageKit.JpegSubsamplingKind JpegSubsampling {get; set;}

Property Value

This value is of type Newtone.ImageKit.JpegSubsamplingKind

Explanation

The JpegSubsampling property sets the YCrCb subsampling ratios when saving an image in JPEG format. Since the Y (luminance or brightness) plane contains more important information about the image than does the CrCb (chrominance or color) planes, it is possible to reduce the size of the CrCb planes without a great sacrifice in quality thereby reducing the size of the image. A ratio for Y:Cr:Cb of 4:4:4 represents no reduction in size whereas a ratio of 4:1:1 represents a reduction in size of 50%.

This property is enabled when the image is 24 bit color and the image is saved as a JPEG image.

This property can only be used when loading or saving JPEG images with the ImageKit.NET3 Win32 Plugin
