Angle of markers

[Regina Henschel <rb...@t-online.de>]

Hi all,

I'm member of Apache OpenOffice project. We are working on import filter 
for SVG graphics. In this context I have looked, how Squiggle renders 
the graphics with markers with orient="auto".

I see, that Squiggle does not consider the direction of the last path 
segment for marker-start in a closed path, and the direction of the 
first path segment for marker-end in a closed path.

I think, because of
   "In all cases for closed subpaths (e.g., subpaths which end with a 
  'closepath' command), the orientation of the marker corresponding to 
the initial point of the subpath is calculated assuming that:
     the path segment going into the vertex is the path segment 
corresponding to the closepath
     the path segment coming out of the vertex is the first path segment 
in the subpath"
in http://www.w3.org/TR/SVG/painting.html#OrientAttribute

marker-start and marker-end have to use angle bisector as well in closed 
paths.

I can provide you with some test files, but do not know whether this 
mailing list allows attachments.

Kind regards
Regina

Yes, you can attach your sample files to the mail message. But the 
batik-dev mailing (instead of batik-users) list is more appropriate for 
this discussion.
