Raphael: Inherited transformations -

-

based on thread (raphaeljs transformations sets) have played around inherited transformations using sets in sets.

i tried put set in set , each set apply 45° rotation. expected, both rotation sum 90° rotation. working fine.

but both rotations relative centerpoint of each single object in set. how can achieve, rotations relative center point of set? possible?

to clarify mean. if have 2 rectangles in set , apply rotation on set, want rectangles stay in same position , angle relative them self, because both rotate around axis between them, in middle of set. must translated additionally rotation...

how can achieve this?

jsfiddle:http://jsfiddle.net/bby9b/

var paper = raphael(0,0,500,500);      var = paper.rect(10,10,50,10); var b = paper.rect(10,30,50,10) var c = paper.rect(10,50,50,10); var d = paper.rect(10,70,50,10);  var set = paper.set()  set.push(a);  set.transform("r-45");  var rootset = paper.set(); rootset.push(set, b, c);  rootset.transform("...r-45");

thx in advance!

the r command takes 2 additional optional parameters centre point of rotation. looks want this:

window.onload = function(){     var paper = raphael(0,0,500,500);          var = paper.rect(10,10,50,10);     var b = paper.rect(10,30,50,10)     var c = paper.rect(10,50,50,10);     var d = paper.rect(10,70,50,10);      var set = paper.set()      set.push(a);      set.transform("...r-45,40,45");      var rootset = paper.set();     rootset.push(set, b, c);      rootset.transform("...r-45,40,45"); }
