Halcon——在C#中各数据类型的相互转换

---

前言

用c#进行Halcon代码转换的时候，虽然有halcon自带的转换，但是当我们外部封装时也同样会用到Hobject ->HRegion,HTuple -> 标准数据类型（int，double，string。。。），在此写下记录，方便以后查看。

一、HObject to

1.HObject to HImage

 		// 转换成灰度图片
        public static HImage HObject2HImage_Gray(HObject hObject)
        {
    
    
            HImage image = new HImage();
            HTuple pointer, type, width, height;
            HOperatorSet.GetImagePointer1(hObject, out pointer, out type, out width, out height);
            image.GenImage1(type, width, height, pointer);

            pointer.Dispose();
            type.Dispose();
            width.Dispose();
            height.Dispose();
            hObject.Dispose();

            return image;
        }

  		// 转换成彩色图片
        public static HImage HObject2HImage_RGB(HObject hobject)
        {
    
    
            HImage image = new HImage();
            HTuple pointerRed, pointerGreen, pointerBlue, type, width, height;
            HOperatorSet.GetImagePointer3(hobject, out pointerRed, out pointerGreen, out pointerBlue, out type, out width, out height);
            image.GenImage3(type, width, height, pointerRed, pointerGreen, pointerBlue);

            pointerRed.Dispose();
            pointerGreen.Dispose();
            pointerBlue.Dispose();
            type.Dispose();
            width.Dispose();
            height.Dispose();

            return image;
        }

二、HTuple to

1.HTuple to Int

代码如下（示例）：

            int val = htuple.I;

2.HTuple to Double

代码如下（示例）：

			double val = htuple.D;

3.HTuple to String

代码如下（示例）：

			string val = htuple.S;

4.HTuple to long

代码如下（示例）：

			long val = htuple.L;

5.HTuple to object

代码如下（示例）：

			object val = htuple.O;

6.HTuple to Arr

转换成上述1-5的各种形式的数组。
如下：

			int[] iArr = htuple.IArr;			
			double[] iArr = htuple.DArr;			
			string[] iArr = htuple.SArr;			
			long[] iArr = htuple.LArr;
			object[] iArr = htuple.OArr;

总结

想要转换首先得能够转换才行欧，整个HTuple中存了个double类型的数据，却用HTuple.I往整型转换是会报错失败的。所以转换前请确保原有数据格式的类型。
