hello,
I want to use iText for my application to print some rich text from a
JTextPane with varying textstyles under Sun JRE 1.4.x / 1.5.x.
But unfortunately I run in a quality-issue as shown in following example.
If you look at the screen-output, there is no gap between the text and the
surrounding rectangele calculated from FontMetric.
But if you look at the pdf-output you see big gap. It seems that the
FontMetric from the com.lowagie.text.pdf.PdfGraphics2D dosen't calculate the
correct fontlength.

Is there something wrong in my code or is there any workaround?
May anybody help me?
kind regards,
