save a JPEG in progressive format [closed]
Magick.NET can do it with a code like this
using (MagickImage image = new MagickImage("input.png")){ // Set the format and write to a stream so ImageMagick won't detect the file type. image.Format = MagickFormat.Pjpeg; using (FileStream fs = new FileStream("output.jpg", FileMode.Create)) { image.Write(fs); } // Write to .jpg file image.Write("PJEG:output.jpg"); // Or to a .pjpeg file image.Write("output.pjpg");}You can find more details here.
