OpenCV中IplImage与Qt中的QImage转化

在工程中由于要涉及到OpenCV中IplImage与Qt中的QImage转化,所以早上写了两个类,

下午打算把这个类封装下，封装成dll形式。

#ifndef IMAGETRANSFORM_H#define IMAGETRANSFORM_H#include "highgui.h"#include "cv.h"#include <QImage>#define RGB_TYPE 3              //R,G,B三通道#define GRAY_TYPE 1             //格雷图，单通道class ImageCVtoQT{public:ImageCVtoQT(IplImage *_srcImage);~ImageCVtoQT();const QImage getQtImage(void);private:IplImage *srcImage;          //原图//QImage desImage;             //转换图int width;int height;int channel;                 //图像通道数};class ImageQTtoCV{public:ImageQTtoCV(QImage _srcImage);~ImageQTtoCV();IplImage *getCvImage(void);private:QImage srcImage;int width;int height;//int channel;};#endif
