[jira] [Created] (FOP-2273) Stroke miter limit is not clamped when
writing PDFs
Max Gilead created FOP-2273:
-------------------------------
Summary: Stroke miter limit is not clamped when writing PDFs
Key: FOP-2273
URL: https://issues.apache.org/jira/browse/FOP-2273
Project: Fop
Issue Type: Bug
Components: pdf
Affects Versions: trunk
Reporter: Max Gilead
org.apache.fop.svg.PDFGraphics2D line 1240 (as of SVN revision 148001 [1]) is:
float ml = bs.getMiterLimit();
but should be (or equivalent):
float ml = Math.max(1.0f, bs.getMiterLimit());
Acrobat Reader (on all platforms) refuses to load graphics data after encountering miter limit < 1.0 and reports an error.
I can't find a reference to the valid range in the PDF spec but Inkscape also had a problem with values less than 1.0 [2] and SVG spec mandates values >= 1.0 as well [3] so clamping the value to 1.0 or more seems like the right thing to do.
