[jira] [Created] (PDFBOX-2089) Negative width of character

Juraj Lonc created PDFBOX-2089:
----------------------------------

             Summary: Negative width of character
                 Key: PDFBOX-2089
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2089
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Juraj Lonc
         Attachments: negative_width.pdf

This PDF contains text matrix:
-10.5679 0 0 -11.4 459.0349 19.4155 Tm

that causes IMHO wrong calculation of character width (and height).
Width and height calculated in PDFStreamEngine are negative numbers, because textMatrix.getXScale() gives negative value.

I think it should be fixed in Matrix.getXScale() and Matrix.getYScale(). Returning value should be fixed by Math.abs()
