Hi all,
playing with bezier curves, i found different rendering if i make path with
severals curves or if i share control points.
Quadratique bezier curves (q1,q2) give the same curve, adding 2 curves in the
path or sharing control points.
Cubic bezier curves (c1,c2 or c3,c4) don't give the same curve.
<path d="M 10 100 L 10 10 200 100 200 10" fill="none" stroke="blue"/>
<!--<path d="M 10 55 Q 10 10 105 55 Q 200 100 200 55 " fill="none"
stroke="red"id="q1"/>
<path d="M 10 55 Q 10 10 105 55 T 200 55 " fill="none" stroke="green"id="q2"/>
-->
<path d="M 10 55 C 10,10 105,55 105,55 C 200 100 200 55 200 55 " fill="none"
stroke="red" id="c1"/>
<path d="M 10 55 C 10,10 105,55 105,55 S 200,100 200,55 200,55 " fill="none"
stroke="green" id="c2" />
<g transform="translate(0,100)">
<path d="M 10,100 L 10,10 M 150,10 L 150,100" fill="none" stroke="blue"/>
<path d="M 150,100 L 150,200 M 250,200 L 250,100" fill="none" stroke="black"/>
<path d="M 10,100 C 10,10 150,10 150,100
C 150,200 250,200 250,100" fill="none" stroke="red"
id="c3"/>
<path d="M 10,100 C 10,10 150,10 150,100
S 250,200 250,100" fill="none" stroke="green"
id="c4"/>
</g>
same result in firefox, opera and chrome
is it normal? is it a bug? intuitively, i thought c1 and c2 should overlap,
same for c2 and c3 as it does for q1 and q2 and the first part of c1,c2 and
c3,c4 ...
hope this helps
