Compressonator.NET Samples

[ProbablePrime]

A library without samples, isn't that desirable. I'm setting up a sample project in #6 but I dont actually know how to use this library or the underlying Native library.

Here's some code from an abandonned conversion sample, that didn't work for 3 hours :D, just in case it is useful for the next person through.

 var sourceTexture = new CMP_Texture();

 var width = 512;
 var height = 512;
 var bitsPerPixel = 4 * 8;

 sourceTexture.width = (uint)width;
 sourceTexture.height = (uint)height;
 sourceTexture.pitch = (uint)BitsToBytes(width * bitsPerPixel);
 sourceTexture.format = CMP_FORMAT.RGB_888;

 sourceTexture.CalculateDataSize();

 var destTexture = new CMP_Texture();

 destTexture.width = sourceTexture.width;
 destTexture.height = sourceTexture.height;
 destTexture.pitch = sourceTexture.pitch;
 destTexture.format = CMP_FORMAT.BC6H;

 destTexture.CalculateDataSize();


 FrameworkNativeMethods.CMP_LoadTexture("input.bmp", )


 var options = new CMP_CompressOptions();

 options.quality =  0.5f;
 options.numThreads = (uint)1;

 var fileBytes = File.ReadAllBytes("input.bmp");
 var outputBytes = new byte[destTexture.dataSize];

 unsafe
 {
     fixed (void* src = fileBytes)
     fixed (void* dst = outputBytes)
     {
         sourceTexture.data = new IntPtr(src);
         destTexture.data = new IntPtr(dst);

         var result = SDK_NativeMethods.CMP_ConvertTexture(sourceTexture, destTexture, options, IntPtr.Zero);

         if (result != CMP_ERROR.CMP_OK)
             throw new Exception("Conversion error: " + result);
     }
 }

 File.WriteAllBytes("output.bmp", outputBytes);
