OK: do you think is better to make this rounding directly in the code
(using a function such as Math.round() ) ? I think the result will be
more predictable this way, won't it?

>>     Hi,
>>
>>     this is my first post to this list. My name is Diego and I am using
>>     iText to generate labels with barcode. I've tried several way of barcode
>>     generation, e.g. as a tempalte with barcode, as an iText image and as an
>>     awt image, but the result is always the same: a kinda anti-aliasing
>>     effect appears on the edge of bars, like a gray 1-pixel line. Since the
>>     data are correct (e.g.: the awt image is only black and white), I would
>>     like to know if there is any way to remove this rendering problem,
>>     because it may cause the barcode not to be read by some instruments.
>>     Actually I am using Interleaved 2 of 5 barcode, but I need to remove
>>     this "anti-aliasing" effect on all barcode type.
>>     All susggestions are welcome.

>>     Thanks in advice,
