I have been testing some scripts to input paths to an SVG display.
These paths include arc commands. The path is added to the DOM in the
following fashion:
var parcel = SVGDoc.getElementById("newParcel");
var n_path = SVGDoc.createElementNS("http://www.w3.org/2000/svg","path";);
n_path.setAttribute("d","M -0.63 -189.43 l 101.32 -139.25 -7.93
-50.31 120.03 -0.16 a 500 500 0 0 0 -213.09 292.84 l -0.33 -103.12 " );
n_path.setAttribute("id","testParcel" );
parcel.appendChild(n_path);
When this is completed as a test to debug I run:
alert(SVGDoc.getElementById("testParcel").getAttributeNS(null,"d");
For IE7 and Firefox I get:
"M -0.63 -189.43 l 101.32 -139.25 -7.93 -50.31 120.03 -0.16 a 500 500
0 0 0 -213.09 292.84 l -0.33 -103.12 "
But for Opera I get:
"M -0.63 -189.43 L 100.69 -328.68L 92.76 -378.99L 212.79 -379.15C
107.661 -311.595 31.6402 -207.122 -0.299988 -86.31C -0.299988 -86.31
-0.299988 -86.31 -0.299988 -86.31C -0.299988 -86.31 -0.299988 -86.31
-0.299988 -86.31C -0.299988 -86.31 -0.299988 -86.31 -0.299988 -86.31L
-0.629988 -189.43"
>From the results it looks like Opera does not store arcs in path data
but instead approximates the arc using multiple Bezier curves.
Can someone confirm this and if true when will Opera support true arcs?
Thanks
