Emgu CV Image 取得資料位置方法

public struct MIplImage

public  IntPtr  imageData
pointer to aligned image data

Emgu.CV.Image<Gray, Byte> img;
img = new Emgu.CV.Image<Gray, Byte>(mwidth, mheight);
ptr = img.MIplImage.imageData.ToInt32();

public  IntPtr  imageDataOrigin
pointer to a very origin of image data (not necessarily aligned) - it is needed for correct image deallocation

Emgu.CV.Image<Gray, Byte> img;
img = new Emgu.CV.Image<Gray,Byte>(mwidth, mheight);
ptr = img.MIplImage.imageDataOrigin.ToInt32();
