> I was notified by Peter Costello (peterwcostello at gmail dot com) that there
> has been a regression in PDFStreamSource, which results in TextPosition
> returning negative individual character widths. This could happen, because I
> only tested with TextPosition#getWidth(), but not with
> TextPosition#getIndividualWidths(). Below is the original message:
> Bug introduced to
> /pdfbox/trunk/src/main/java/org/apache/pdfbox/util/PDFStreamEngine.java on
> revision 885904
> Line 422 changed to:
> float widthText = glyphMatrixStDisp.getXPosition() -
> glyphMatrixEndDisp.getXPosition();
> Polarity of width now negative. Should be
> float widthText = glyphMatrixEndDisp.getXPosition() -
> glyphMatrixStDisp.getXPosition();
