title: Scaling Image Data to Bigger Size
body: <p>First I have a canvas area,</p>
  
  <p>I am cropping some part from its image data then i want to show that cropped part stretched to full canvas scale.</p>
  
  <p>Like.</p>
  
  <p>i have a canvas of area say 400,400,</p>
  
  <p>and then i crop image data from (20,100) to (200,300) that means of 180(width) and 200(height)</p>
  
  <p>and afterwards i want that cropped part to be shown on the same canvas stretched to its full width and height.</p>
  
  <p>Is it possible through javascript part or do we need to create our own function for that purpose.</p>
