Usage example

 using PaintDotNet;
 using DdsFileTypePlus;
 void Main()
 { 
 progressBar1.Minimum = 0;
 progressBar1.Maximum = 100;
 progressBar1.Value = 0;
 Surface surface = DdsFile.Load(@"S:\testDDS\BC7.dds"); //get Paint.NET Surface
 
 System.Drawing.Bitmap bitmap = surface.CreateAliasedBitmap(); // convert to Bitmap
 MagickImage magickImage = new MagickImage(bitmap); // convert to Magick.NET MagickImage
 NetVips.Image vipsImage;
 using (var stream = new MemoryStream())
 {
 bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
 vipsImage = Image.NewFromBuffer(stream.ToArray()); // convert to NetVips Image
 }
 
 // do something with images
 
 System.Drawing.Bitmap processedBitmap = magickImage.ToBitmap();

 fileStream.Close();
 }
 private void ProgressChanged(object sender, ProgressEventArgs e)
 {
 progressBar1.Value = (int) Math.Round(e.Percent);
