Hi Pradeep L,
Please try to use the following code.
Metafile mf_test = new Metafile(filePath);
Bitmap bmpImage = new Bitmap(mf_test);
Bitmap bmpCrop = bmpImage.Clone(new Rectangle(0, 0, 800,600), bmpImage.PixelFormat);
bmpCrop.Save("Object 6.emf");
Here is my cropped image.

Source EMF:
Object 6.emf
Best regards,
Kristin
