Sorry I forgot mailing lists in CC ! Hi Jim,
Did you start looking at early rejection of segments (clipping) ? On my side, I looked at the Stroker class and I figured out why it generates so many segments (4M) for my 800k spiral: mitter join are generated with many intermediate segments. I wrote the StrokerTest class to illustrate this issue : it uses the createStrokedShape() to illustrate / check what the renderer does (stroking, dashing, culling). Here is the ductus / pisces output with cap = CAP_BUTT (no extra cap decoration) and join = MITTER_JOIN: you can see mitter joins are made with several segments: 2 extra segment per join. I started understanding and hacking the drawJoin() method = some quick & dirty hacks to remove the intermediate point and use the intersection point instead. - Marlin without collinear Simplifier: - Marlin with collinear Simplifier: it removes collinear segments: To conclude, it is promising (many tests with curves remain) but I would prefer avoiding generating such extra segments in the Stroker / Dasher as early as possible ... but it seems more tricky ! PS: Cap decoration have the same issue: it generates 3 extra segments for CAP_SQUARE, but the collinear simplifier eliminate superfluous segments. Does anybody have any idea / opinion ? Is there any reason to generate these intermediate segments (winding rule, ...) as ductus / pisces does ? Does it seem possible to remove them definitely for the marlin renderer at least ? Cheers, Laurent
