c# - Center drawn Ellipse origin -

-

i'm trying make simple animation circle expanding , fading away, problem have is expanding top left , want expand center, iv'e tried setting rendertransformorigin (0.5, 0.5) still don't works.

this code:

ellipse impact = new ellipse();     impact.width = 50;    impact.height = 50; impact.strokethickness = 1.5f;  impact.rendertransformorigin = new point(0.5, 0.5); maincanvas.children.add(impact);   storyboard story = new storyboard(); doubleanimation anim = new doubleanimation(0, 60, timespan.fromseconds(0.9)); doubleanimation anim2 = new doubleanimation(0, 60, timespan.fromseconds(0.9)); doubleanimation anim3 = new doubleanimation(1, 0, timespan.fromseconds(0.9));   storyboard.settargetproperty(anim, new propertypath("(ellipse.height)")); storyboard.settargetproperty(anim2, new propertypath("(ellipse.width)")); storyboard.settargetproperty(anim3, new propertypath("(ellipse.opacity)"));  story.children.add(anim); story.children.add(anim2); story.children.add(anim3);  impact.beginstoryboard(story);

setting rendertransformorigin property without setting rendertransform has no effect.

what want animate path ellipsegeometry instead of ellipse:

var impact = new path {     data = new ellipsegeometry(new point(25, 25), 25, 25),     strokethickness = 1.5,     stroke = brushes.black };  maincanvas.children.add(impact);  storyboard story = new storyboard(); doubleanimation anim1 = new doubleanimation(0, 30, timespan.fromseconds(0.9)); doubleanimation anim2 = new doubleanimation(0, 30, timespan.fromseconds(0.9)); doubleanimation anim3 = new doubleanimation(1, 0, timespan.fromseconds(0.9));  storyboard.settargetproperty(anim1, new propertypath("data.radiusx")); storyboard.settargetproperty(anim2, new propertypath("data.radiusy")); storyboard.settargetproperty(anim3, new propertypath("opacity"));  story.children.add(anim1); story.children.add(anim2); story.children.add(anim3);  impact.beginstoryboard(story);

you may adjust ellipsegoemetry's center , radius achieve desired effect. not clear why circle starts radius of 25, animated 0 30.
