NExifTool

A .NET library to wrap the functionality of ExifTool.

Motivation

To create a simple wrapper around this excellent program to allow .NET programs to easily access exif data for images.

Installation

NExifTool depends on ExifTool from https://www.sno.phy.queensu.ca/~phil/exiftool/ in order to work, therefore, ExifTool must be installed.
NExifTool can then be added to your project via the NuGet package.

Usage

using System.Threading.Tasks;
using NExifTool;

namespace Test
{
    public class Example
    {
        public async Task Test(string srcFilename)
        {
            var et = new ExifTool(new ExifToolOptions());
            var list = await et.GetTagsAsync(srcFilename);

            // use list...
        }
    }
}

Developing

The exiftool.xml file was produced using the latest ExifTool on my system, using the command: exiftool -listx. This file is then processed to produce a lookup table of tags / english descriptions, which is then used when parsing out the results. This xml file is the input to the XSLT that generates the TagMetadata.cs file.
