title: How to provide dpi/resolution parameter to ZXing Library?
body: <p>I am trying to use ZXing to create code 128 based 1D barcodes.
  I have a requirement to specify the resolution or dpi parameter to generate the 1D barcode.
  But I am unable to find this param in the specification?</p>
  
  <p>Is there any way to do so? What am I missing?</p>
  
  <p>If ZXing does not provide this option, is there any other library which provides the same?</p>
  
  <p>Thanks </p>
