John Hewson commented on PDFBOX-1940:
-------------------------------------
This problems was caused by two errors in the way that the stroke width was
being calculated. Firstly, the width was only multiplied by the CTM if the
{{ctm.getXScaling()}} was > 0, in this case the width was large than the page
and the scaling was a -ve number, so the giant width was left unscaled.
Secondly, the CTM transform was applied by using {{ctm.getXScaling()}} which
ignores the y-scaling, I've replaced the calculation with the average euclidian
distance, which seems to work.
These changes are in trunk in revision 1571803.
