John Hewson reassigned PDFBOX-1939:
-----------------------------------
Assignee: John Hewson
> Store all stroke information in the graphics state
> --------------------------------------------------
>
> Key: PDFBOX-1939
> URL: https://issues.apache.org/jira/browse/PDFBOX-1939
> Project: PDFBox
> Issue Type: Improvement
> Components: Rendering
> Affects Versions: 2.0.0
> Reporter: John Hewson
> Assignee: John Hewson
>
> Recently PDFBOX-1917 has fixed an issue with how the current AWT stroke is
> calculated. This prompted me to look at the file from PDFBOX-1094 which
> contains separate stroking errors. This led to the identification of a
> problem: the BasicStroke is being used to keep track of the stroke state,
> rather than using the information from the graphics state. This fails when
> the graphics state is modified e.g. Save/Restore and the BasicStroke in
> PageDrawer is not correspondingly updated.
> Having looked at the code, it seems that this is a long-standing issue. The
> solution is to remove the BasicStroke variable from PageDrawer and to
> calculate it each time it is needed, using only the information stored in the
> graphics state. The following classes which directly modify the BasicStroke
> can be removed:
> pagedrawer.SetLineCapStyle
> pagedrawer.SetLineDashPattern
> pagedrawer.SetLineJoinStyle
> pagedrawer.SetLineMiterLimit
> pagedrawer.SetLineWidth
