php中rectangle函数怎么用,rectangle函数的使用

代码：

#include 

#include 

usingnamespacestd;

usingnamespacecv;

intmain()

{

char*imageSrc ="I:\OpenCV Learning\picture\sumpalace.jpg";

Mat matImage = imread(imageSrc,-1);

IplImage *iplImage = cvLoadImage(imageSrc,-1);

if(matImage.data==0||iplImage->imageData ==0)

{

cout<

return-1;

}

cv::rectangle(matImage,cvPoint(20,200),cvPoint(200,300),Scalar(255,0,0),1,1,0);

//Rect(int a,int b,int c,int d)a,b为矩形的左上角坐标,c,d为矩形的长和宽

cv::rectangle(matImage,Rect(100,300,20,200),Scalar(0,0,255),1,1,0);

cvRectangle(iplImage,cvPoint(20,200),cvPoint(200,300),Scalar(0,255,255),1,1,0);

imshow("matImage",matImage);

cvShowImage("IplImage",iplImage);

waitKey();

return0;

}

#include

#include

using namespace std;

using namespace cv;

int main()

{

char *imageSrc = "I:\OpenCV Learning\picture\sumpalace.jpg";

Mat matImage = imread(imageSrc,-1);

IplImage *iplImage = cvLoadImage(imageSrc,-1);

if(matImage.data==0||iplImage->imageData ==0)

{

cout<

return -1;

}

cv::rectangle(matImage,cvPoint(20,200),cvPoint(200,300),Scalar(255,0,0),1,1,0);

//Rect(int a,int b,int c,int d)a,b为矩形的左上角坐标,c,d为矩形的长和宽

cv::rectangle(matImage,Rect(100,300,20,200),Scalar(0,0,255),1,1,0);

cvRectangle(iplImage,cvPoint(20,200),cvPoint(200,300),Scalar(0,255,255),1,1,0);

imshow("matImage",matImage);

cvShowImage("IplImage",iplImage);

waitKey();

return 0;

}

结果：

如果需要在Mat类型的图上绘制矩形，选择cv::trctangle()

在IplImage*类型的图上绘制矩形，选择cvRectangle()
