1. Bitmap 转 HImage

由于Bitmap 在转化时使用BitmapData数据，BitmapData数据无法Dispose, 所以在使用时，使用using：

            try{using (Bitmap b = bmp.Clone() as Bitmap){if (bmp == null){image = null;return;};Rectangle rect = new Rectangle(0, 0, bmp.Width, bmp.Height);BitmapData srcBmpData = b.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format8bppIndexed);HObject _image;HOperatorSet.GenImage1(out _image, "byte", b.Width, b.Height, srcBmpData.Scan0);image = new HImage(_image);_image.Dispose();b.UnlockBits(srcBmpData);srcBmpData = null;}}catch (Exception ex){Console.WriteLine(ex.Message);Console.WriteLine(ex.Source);Console.WriteLine(ex.StackTrace);image = null;}

2. new 之后要Dispose()

HObject obj = new HObject(image);
HOperatorSet.ZoomImageFactor(obj, out hoImageZoomed, scaleR, scaleC, "constant");
obj.Dispose();

不能直接使用

HOperatorSet.ZoomImageFactor(new HObject(image), out hoImageZoomed, scaleR, scaleC, "constant");
