Hi Nicola,
So - I'd rather propose the following change (I also added lots of
comments to help future bug fixings) - if you can test it and it's Ok, we
could use this one -
I tested it: it doesn't do the job.
startAngle = 0
endAngle = -450
clockwise
it wouldn't work... it would draw a
Hi Georg,
startAngle = 0
endAngle = -450
clockwise
it wouldn't work... it would draw a full circumference rather than simply
from -90 to 0
Thats exactly what it does, and I think its the correct behavior.
Ok - so we don't agree on what the API is supposed to do. :-)
To add to
Hi Nicola,
Does this patch look right to you ?
Absolutely, and it works for all I've tested.
...but I
think the macos-x doc for NSBezierPath says that we should not draw the
line in NSBezierPath. I need to look at it - but if the backend is using
NSBezierPath to draw the arc, then what
I sligthly simplified the
formula used for F - not that I changed it (unless I made a typo) - just
did some trivial algebraic/trigonometric simplifications. But as I didn't
test it, please tell me if I did something wrong.
It works fine.
Now, here is the fix for the remaining problem, I
Hi Nicola,
Thanks - I read your patch and it made lot of sense - so I applied it. I
did not test it nor did I check on books the formula used to build the
bezier path for the last bit of the arc, so I hope you did. :-)
Yes, I have tested it.
Anyway, I had to realized another little problem

Hi,
attached is a patch with a bunch of fixes for NSBezierPath to make arcs being
displayed.
With the patch arcs should now work in any direction and angle.
I also added a few lines of discription which I found in the ghostscript code.
