JpegColorSpace Property

Gets or sets the value that represents the color space to be used in the image optimization operation.

public ImageOptimizerJpegColorSpace JpegColorSpace { get; set; } 
property ImageOptimizerJpegColorSpace JpegColorSpace { 
   ImageOptimizerJpegColorSpace get(); 
   void set (    ImageOptimizerJpegColorSpace ); 
JpegColorSpace # get and set (ImageOptimizerOptions) 

Property Value

The default value is ImageOptimizerJpegColorSpace.JpegColorSpace411.


The JpegColorSpace is used if and only if the original image format was one of the following Jpeg formats:
