-------------------------------------
Take a look at Java's built-in
[TextLayout|http://docs.oracle.com/javase/6/docs/api/java/awt/font/TextLayout.html]
and
[LineBreakMeasurer|http://docs.oracle.com/javase/6/docs/api/java/awt/font/LineBreakMeasurer.html]
classes.
> Listbox controls render incorrectly

> URL: https://issues.apache.org/jira/browse/PDFBOX-2249
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Affects Versions: 1.8.6
> Environment: Windows 7
> Reporter: John McDonald
> Assignee: Maruan Sahyoun

> I have a form with a listbox. I update the value in the listbox using the
> following code:
> PDChoiceField c = (PDChoiceField)f;
> ((PDChoiceField)f).setValue("2");
> I have a combo box that uses the same choices, and it works fine. The issue
> has to do with the rendering of the field. The update of the value (i.e.
> setValue method) works fine, but when I look at the resulting output PDF the
> choices have become unreadable because the font has gone way large.
> I have searched the mailing list, and posted a question regarding this that
> no one has answered, so I am now assuming this is an unknown bug.
> Thanks
