OPENGL:
main()函数
int window1 = 0,window2 = 0; glutInit(&argc,argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); glutInitWindowSize(ImageWidth,ImageHeight); glutInitWindowPosition(1920,0); window1 = glutCreateWindow("1"); glutDisplayFunc(display1); glutInitWindowPosition(1920+1280,0); window2 = glutCreateWindow("2"); glutDisplayFunc(display2); glutMainLoop();
void display1() { glClear(GL_COLOR_BUFFER_BIT); glDrawPixels(ImageWidth,ImageHeight,GL_BGR_EXT,GL_UNSIGNED_BYTE,PixelData1); glutSwapBuffers(); } void display2() { glClear(GL_COLOR_BUFFER_BIT); glDrawPixels(ImageWidth,ImageHeight,GL_BGR_EXT,GL_UNSIGNED_BYTE,PixelData2); glutSwapBuffers(); }
OPENCV:
stringstream winName; for(int i = 0;i < DISPLAYWINDOWS;i++) { winName.clear();winName.str(""); winName<<i; namedWindow(winName.str(),CV_WINDOW_NORMAL); cv::moveWindow(winName.str(),1920 + ImageWidth * i,0); setWindowProperty(winName.str(), CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN ); } for(int i = 0;i < DISPLAYWINDOWS;i++) { winName.clear();winName.str(""); winName<<i; imshow(winName.str(),disLoop[i]); waitKey(1); }
主要用到的是moveWindow这个函数。
