title: showing .tif images in matlab
body: <p>I am trying to show a .tif image in matlab and I use these two line of codes</p>
  
  <p>a = imread('C:\Users\sepideh\Desktop\21_15.tif');
   imshow(a)</p>
  
  <p>that encounters this warning</p>
  
  <p>Warning: Image is too big to fit on screen; displaying at 3% </p>
  
  <blockquote>
    <p>In imuitools\private\initSize at 73
      In imshow at 262</p>
  </blockquote>
  
  <p>what is the cause of this warning and what can I do to fix that?
  the main trouble is it sometimes doesn't show the image and of course even if it shows the image CPU usage gets high that I can't zoom properly</p>
