HW7 - Callback function (以Mouse為例)

改寫HW5程式, 可使Logo可以依照Mouse的目前位置, 動態坎入fruits影像中

//onMouse callback function
cvSetMouseCallback("mergesrc",onMouse,NULL);
onMouse(0,0,0,1,NULL);

void onMouse(int Event,int x1,int y1,int flags,void* param )
{

if (Event == CV_EVENT_MOUSEMOVE) {
if( (logoImg->height + y1) <>height) {
// Insert lego into an image

}
}
}
