Not sure if this is the answer, but I don't understand why you say that the showTextAligned() uses integers. In fact, it uses floating-point values. See the Javadoc http://1t3xt.info/api/com/lowagie/text/pdf/PdfContentByte.html#showTextAligned(int,%20java.lang.String,%20float,%20float,%20float,%20boolean)
Likewise, setFontAndSize() takes a floating-point value. Again, look at the JavaDoc. I suspect that you can tweak the values to fit perfectly. ---mr. bean >>> re >>> Stepan RYBAR wrote: > > Hello, > > I have a problem using FOP 0.95 and iText 2.1.3 for exact overprint.
