I need to produce a square thumbnail image. I'm using the WriteCropped method. When I first call AlignToSampleSize with my (square) Rectangle. It returns a non-square. Is it possible to use AlignToSampleSize and WriteCropped to force a square crop?

Hello Paul, To crop image with square, you can use juts WriteCropped method defining x, y coordinates of left top corner, and crop size: Code:
Aurigma.GraphicsMill.Codecs.LosslessJpegTransform losslessJpeg = new Aurigma.GraphicsMill.Codecs.LosslessJpegTransform(@"C:\1.jpg");
losslessJpeg.WriteCropped(@"c:\2.jpg", new System.Drawing.Rectangle(0,0,200,200));
losslessJpeg.Close();
or Crop method of Transforms class: Code:
Aurigma.GraphicsMill.Bitmap bitmap = new Aurigma.GraphicsMill.Bitmap");
Aurigma.GraphicsMill.Codecs.JpegReader jpegReader = new Aurigma.GraphicsMill.Codecs.JpegReader(@"C:\1.jpg");
using (Aurigma.GraphicsMill.Codecs.IFrame frame = jpegReader.LoadFrame(0))
{
frame.GetBitmap(bitmap);
}
bitmap.Transforms.Crop(new System.Drawing.Rectangle(0, 0, 200, 200));
Aurigma.GraphicsMill.Codecs.JpegEncoderOptions encoderOptions = new Aurigma.GraphicsMill.Codecs.JpegEncoderOptions(100, true);
bitmap.Save(@"C:\2.jpg", encoderOptions);
