NCV Sharpmagic

Tiny C# P-invoking client class built on top off libmagic (see e.g.) LibMagic. Should work on all platforms that have Libmagic as part of the OS package (including macOS). The idea behind mime-type recognition is using magic numbers and some other features.

Description

Wraps basic LibMagic calls in order to get mimetype and file type properties (if possible) using the well known library which is mostly standard on Linux

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
  • Only supporting linux or OS-es that have libmagic as part of the OS.

How To Use

To clone and run this application, you'll need Git From your command line:

# Clone this repository
$ git clone https://github.com/egbertn/SharpMagic


Credits

This software uses the following open source packages:

  • [Libmagic]
  • Hey-Red (inspired this code)

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]
