Attachment: svgpathpointFinal.jpg

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140317233948

Steps to reproduce:

I am working on svg based application. here user can draw different shapes like rect,circle,line etc. I need to convert these shapes into 'path' and then i need all points in the path.
My solution is working fine for all shapes, except 'circle'. once user finishes the drawing, i convert the circle to 'path' using 'arc'. and when i try to find path point using 'getPointAtLength' , i get different values in Firefox, which changes the end result.
here is the Fiddle Link:- http://jsfiddle.net/xfpDA/


Actual results:

My circle is distorted


Expected results:

it should be a perfect circle.

I can reproduce in
 Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:28.0) Gecko/20100101 Firefox/28.0

But happily, it's already fixed in trunk:
 Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0
 31.0a1 (2014-03-19)

Resolving as WORKSFORME. (Might be useful to find out what fixed it, though.)

Got pointAtLength issues on OSX, FF 32.0.1

Point coordinates out of line.

In firefox 29 it was ok.

Sounds like that merits a new bug, then, given that it worked in Firefox 29.  Could you file a new bug?

(You're definitely not seeing an instance of *this* bug, since this was about something that was broken in Firefox 28.)
