Hello, I've downloaded OpenCV and made a simple program which takes a photo of you using the webcam. But the size of photos is only 160x120 so I was wondering if I can somehow scale it. I tried to use cvResize but it didn't help. Can anybody help me? Here is the code:
int main() {
CvCapture *webcam = cvCreateCameraCapture(0);
if (!webcam)
return 1;
while (1) {
IplImage *camImg = cvQueryFrame(webcam),*camImgSize = cvCreateImage(cvSize(640,480),camImg->depth,camImg->nChannels);
if (camImg) {
cvResize(camImg,camImgSize,CV_INTER_LINEAR);
cvSaveImage("photo.jpg",camImg,0);
cvShowImage("Photo",camImg);
if (cvWaitKey(3000) == 0x1B) break;
}
}
return 0;
}
