Full image not coming using imshow - c++

Question

I have an image of dimension 4096 X 2304. I can view that Image when double click.
Then i wanted to write my own opencv (ver 2.4.3) program to display this image. But The image is not fitting on the screen. It is showing only 50%, rest of the part is cutting.
This my code for image display:
#include "stdafx.h"
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("1.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The screen resolution of my monitor is 1366 x 768 maximum.
So why my program is unable to display the full uncut image?

Answer 1

Try this (I have done partial editing of your code, just the gutsy bits 0_0 ):
Mat im_s = imread("myimg", CV_LOAD_IMAGE_COLOR);
if (im_s.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
namedWindow( "Myimg", WINDOW_AUTOSIZE );
Size size(4096,2304);
Mat im;
resize(im_s, im, size);
imshow("Myimg", im);
waitkey(0);
return 0;
