SharpLibraw

C#.NET wrapper around Libraw. Wrapper class rawlib.cs includes C# signatures for all external native methods from libraw.dll.

Try the demo console application Program.cs which demonstrates key libraw features, like:

initialize library
open raw file
export raw file to TIFF
export thumbnail from raw file to JPEG
load raw data, process it and export to Windows bitmap
error handling

Demo project

To successfully build wrapper and demo application the following steps are needed:

Download and install Visual Studio 2017 or 2019 Community Edition.
Open LibRAWDemo.sln solution file and start build.
The built executable LibRAWDemo.exe requires to have the included libraw.dll library in the same folder (should be there automatically)!
Note: 64bit build of the project is required, since the included libraw.dll is also a 64bit library!

Sample usage of wrapper

using System;
using static LibRAWDemo.RAWLib;

class Program {
	static void Main(string[] args) {
		var handler = libraw_init(LibRaw_init_flags.LIBRAW_OPTIONS_NONE);
		libraw_set_output_tif(handler, LibRaw_output_formats.TIFF);
		libraw_set_no_auto_bright(handler, 0);
		var r = libraw_open_file(handler, @"C:\Temp\RawFile01.cr2");
		if (r != LibRaw_errors.LIBRAW_SUCCESS) {
			Console.WriteLine("Open file:       " + PtrToStringAnsi(libraw_strerror(r)));
			libraw_close(handler);
			return;
		}
		r = libraw_unpack(handler);
		r = libraw_dcraw_process(handler);
		r = libraw_dcraw_ppm_tiff_writer(handler, @"C:\Temp\Processed01.tiff");
		libraw_close(handler);
	}
}
