tested with Aspose.Barcode for Java, versions 2.2.0 and 2.7.0, with symbologies “datamatrix” and "qr"
When using auto-size, there is a superfluous column of background pixels at the right, and the lowest row of dots is always only 1 pixel high. getHeight gives a wrong value, and the actual size of the generated image is still different.
Everything works when I set auto-size to false and set the desired dimensions myself.
E.g. with datamatrix, this is what I get (with borders and margins set to 0):
xdim/ydim=1, expected: 16x16, getWidth/getHeight: 16x15, actual image: 17x16
xdim/ydim=2, expected: 32x32, getWidth/getHeight: 32x30, actual image: 33x31
xdim/ydim=3, expected: 48x48, getWidth/getHeight: 48x45, actual image: 49x46
