----------------------------------------
Feel free to assign it to me - I have off next week and planned to do some
PDFBox programming.

> Key: PDFBOX-5784
> URL: https://issues.apache.org/jira/browse/PDFBOX-5784
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Reporter: Tilman Hausherr
> Priority: Major
> Attachments: screenshot-1.png, with_dividing_by_2.pdf,
> without_dividing.pdf
>
>
> The user in the attached SO question noticed that the comb adjustment needed
> a factor of 2 to work correctly. A look at the font shows UnitsPerEm = 2048.
> Sample code:
> {code:java}
> doc.getDocumentCatalog().getAcroForm().getField("field1").setValue("WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW");
> doc.getDocumentCatalog().getAcroForm().getField("field2").setValue("MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM");
> {code}
> !screenshot-1.png!
