Nierop Computer Vision Sharpmagic

tiny C# client class built on top off libmagic Library which exist on must Linux distributions

Key Features

• Highly optimized for low resource usage.
• Enables using the libmagic library to retrieve mime types or file info (as properties)
• e.g.

detected mimetype = ISO Media,MP4 Base Media v1 [IS0 14496-12:2003] detected mimetype = JPEG image data,JFIF standard 1.01,aspect ratio,density 1x1,segment length 16,baseline,precision 8,1200x826 components 3

• Supports only linux. Windows not tested and probably will not, since libmagic is not an out of the box component.

Usage

Register SharpMagic as singleton e.g.

// somewhere in program.cs / startup.cs
  services.AddSingleTon<SharpMagic>();
  //or directly:
  SharpMagic sharpMagic = new();

// somewhere in your code
  using var mp4 = File.OpenRead("tesje.mp4");
  var (mp4MimeType, _) = sharpMagic.GuessMimeType(mp4, 2048, true);
  Console.WriteLine($"detected mimetype = {mp4MimeType}");

  using var jpg = File.OpenRead("gun.jpg");
  var (mimeType, _) = sharpMagic.GuessMimeType(jpg, mimeOnly: true);

  Console.WriteLine($"detected properties = {string.Join(',', dll.GuessMimeType(Path.GetFullPath("gun.jpg")).Properties)}");

output:
detected mimetype = video/mp4
detected mimetype = image/jpeg
detected properties = JPEG image data,JFIF standard 1.01,aspect ratio,density 1x1,segment length 16,baseline,precision 8,1200x826,components 3
detected properties = ISO Media,MP4 v2 [ISO 14496-14]
