You can use LEADTOOLS Imaging Pro SDK technology in your application.
https://www.leadtools.com/sdk/products/imaging-pro
You can leverage the CropCommand class, which will allow you to take the points you have and crop your image.
See the code below:
string srcFileName = @"FILE PATH TO INPUT IMAGE";
string destFileName = @"FILE PATH TO OUTPUT CROPPED IMAGE";

using (RasterCodecs _codecs = new RasterCodecs())
using (RasterImage _image = _codecs.Load(srcFileName))
{
    CropCommand _cmd = new CropCommand();
                _cmd.Rectangle = new LeadRect(
        int left,
        int top,
        int width, int height);

                _cmd.Run(image);

    _codecs.Save(_image, destFileName, RasterImageFormat.Tif, 24);
}
