save a JPEG in progressive format [closed]

Question

A similar question has already been asked on this thread:

Save JPG in progressive format

However, the answer marked is basically saying that it can't be done. However, considering it is done using other software, it definitely is something which C# can do.

Is there any way this can be done?

Answer 1

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");
}
