title: Does scaling of barcode image damages it?
body: <p>I have a barcode image. I have to make it smaller.</p>
  
  <p>Can that damage the barcode?</p>
  
  <ol>
  <li><p>Proportional scaling</p></li>
  <li><p>Not proportional scaling (only height changes)</p></li>
  </ol>
  
  <p>Barcodes are: Type UPC-A / EAN-13 "vertical lines". Sorry not an expert in barcodes, thought the type of barcode would not be important. Scaling is moderate, the image does not lose relevant data.</p>
