In kineticjs, is it possible to save complex shapes to json and restore it? -


i can't seem to work. know can built in shape functions such circle, polygon complex shapes, can still serialize if @ json string, don't see x,y coordinate. jsfiddle.net/q7g99/1/. serialize , de-serialize don't give errors nothing appear on canvas.

the "primitive" shapes (kinetic.rect, kinetic.circle, etc) use properties define shapes.

the kinetic.shape uses context drawing commands define shape.

properties can serialized -- drawing commands cannot.

that's why kinetic.shape not serialize.

as workaround, save scenefunc function in .js file that's loaded page.

eg. in myshapescenefuncs.js:

// scenefunc code var shape1=new kinetic.shape  function shape1scenefunc(context) {     context.beginpath();     context.moveto(200, 50);     context.lineto(420, 80);     context.quadraticcurveto(300, 100, 260, 170);     context.closepath();     // kineticjs specific context method     context.fillstrokeshape(this); }   // rewire scenefunc shape1  shape1.scenefunc(shape1scenefunc);
