  • Fixed height didn't work correctly in PdfPCell.
  • CFFFontSubset: avoiding a NullPointerException
  • XfaForm: skipping white space
  • BaseFont: Not all the xobjects have resources and that was causing a NullPointerException.
  • Java 5 code simplifications in PdfCopy and PdfContentByte
  • PdfPTable: New method to reset the number of columns.

  • LocationTextExtractionStrategy: Fixed anti-parallel algorithm, plus accounting for negative inter-character offsets. Change to text extraction strategy that builds out the text model first, then computes concatenation requirements.

  • Replacing getStartPoint and getEndPoint with getLineSegment.
  • PdfDictionary: new method clear()
  • PdfCollection: Collections can also have a custom view.
  • PdfAnnotation: suggestion by Eric de Beus to add a method to create Polygon/Polyline annotations. As the two methods suggested by Eric were identical except for one line, I merged them into one method.
  • BaseFont: TrueTypeFont.WindowsMetrics.usWeightClass and usWidthClass and made both accessible via TrueTypeFont.getFontDescriptor() (posted to the mailing list by Thimo Seitz 14/07/2009 14:12)
  • Tabs and justified alignment don't mix. Not really a bug fix, but at least the line doesn't jump out of the text column anymore.
  • FDF files are now generated as version 1.4 (instead of 1.2)
