使用 GetEncoder() 需要什么参考？

Question

I am trying to save an image with a specific quality parameters and following this example from Microsoft Docs .

I can't find a way to use GetEncoder() like shown on this line ImageCodecInfo jpgEncoder = GetEncoder(ImageFormat.Jpeg);

What reference do I need to use this function?

I tried going to this page and tried to use `System.Text.Encoding, but it doesn't seem to work.

Answer 1

GetEncoder() is manually defied in the given example using ImageCodecInfo.GetImageEncoders(); to implement it.
