{
CvRect roi = new CvRect(320, 260, 100, 100); // region of roosevelt's face
using (IplImage src = new IplImage(Const.ImageYalta, LoadMode.Color))
using (IplImage dst = new IplImage(roi.Size, BitDepth.U8, 3))
{
src.ROI = roi;
using (Bitmap bitmap = new Bitmap(roi.Width, roi.Height, PixelFormat.Format32bppArgb))
using (Graphics g = Graphics.FromImage(bitmap))
{
//BitmapConverter.DrawToGraphics(src, g, new CvRect(new CvPoint(0, 0), roi.Size));
IntPtr hdc = g.GetHdc();
BitmapConverter.DrawToHdc(src, hdc, new CvRect(new CvPoint(0,0), roi.Size));
g.ReleaseHdc(hdc);
g.DrawString("Roosevelt", new Font(FontFamily.GenericSerif, 12), Brushes.Red, 20, 0);
