Used to specify the parameter value passed to a JPEG or TIFF image encoder when using the System.Drawing.Image.Save(string, ImageCodecInfo, EncoderParameters) or System.Drawing.Image.SaveAdd(EncoderParameters) methods.
Syntax
Remarks
When you call the System.Drawing.Image.Save(System.IO.Stream, ImageCodecInfo, EncoderParameters) or System.Drawing.Image.SaveAdd(System.Drawing.Image, EncoderParameters) method of an System.Drawing.Image object, you can pass parameters to the image encoder by passing an System.Drawing.Imaging.EncoderParameters object to the erload:System.Drawing.Image.Save or erload:System.Drawing.Image.SaveAdd method. An System.Drawing.Imaging.EncoderParameters object contains an array of System.Drawing.Imaging.EncoderParameter objects. Each System.Drawing.Imaging.EncoderParameter object has an array of values and an System.Drawing.Imaging.Encoder property that specifies the parameter category. The System.Drawing.Imaging.EncoderValue enumeration provides names for some of the values that can be passed to the JPEG and TIFF image encoders.
