JPEG is defined in ITU-T T.81: https://www.w3.org/Graphics/JPEG/itu-t81.pdf. scan.go writer.goPackage-Level Type Names (total 4)A FormatError reports that the input is not a valid JPEG. ( FormatError) Error() string FormatError : errorOptions are the encoding parameters. Quality ranges from 1 to 100 inclusive, higher is better. Quality int func Encode(w io.Writer, m image.Image, o *Options) errorDeprecated: Reader is not used by the image/jpeg package and should not be used by others. It is kept for compatibility.
