QR Barcode size within an image

Jun 23, 2015 at 12:26 PM

I am generating QR images which are 150 x 150px. I am finding that the length of the data which I encode into the barcode effect the size of the QR block within the image. Is there a way to force the QR block to be a particular size. The Encoding hints and Encoding options for height and width are only affecting the actual image.
