How to rotate a dojox gfx at a new position?
The shape is moveable and has to be rotated and scaled at the new position. For demonstration i have used the Butterly Demo from dojox gfx . See this example at jsfiddle for the moveable butterfly .
How is it possible to rotate and scale the shape at the new position and the new center?
Thanks in advance,
mbecker
I forked your jsFiddle ( http://jsfiddle.net/phusick/ta65D/ ) and added two instances of dijit/form/NumberSpinner
(translateX & translateY) to move the butterfly thanks to modified updateMatrix
function:
var updateMatrix = function() {
var translateX = xSpinner.get("value");
var translateY = ySpinner.get("value");
var centerX = 210 + translateX;
var centerY = 170 + translateY;
if(g) {
g.setTransform([
m.rotategAt(rotation, centerX, centerY),
m.scaleAt(scaling, centerX, centerY),
m.translate(translateX, translateY)
]);
}
};
EDIT: To add mouse DnD support add the following code to the aforementioned:
var moveable = new Moveable(g); // require("dojox/gfx/Moveable")
moveable.onMoved = function(mover, shift) {
xSpinner.set("value", xSpinner.get("value") + shift.dx);
ySpinner.set("value", ySpinner.get("value") + shift.dy);
}
Of course, you do not have to use NumberSpinner
, but since I put it there before it gives you a nice feedback what is going on behind the scenes. See it at jsFiddle: http://jsfiddle.net/phusick/ta65D/ .
