Scale image on dragging using famo.us -

-

i new famo.us, trying scale image on dragging.my code working fine 1 drag after not working. how can make work fro every drag? settransform make scale operation fixed?

define(function(require, exports, module) { var engine              = require("famous/core/engine"); var surface             = require("famous/core/surface"); var statemodifier       = require("famous/modifiers/statemodifier"); var draggable           = require("famous/modifiers/draggable"); var transform           = require("famous/core/transform"); var imagesurface        = require('famous/surfaces/imagesurface'); var maincontext = engine.createcontext(); var size_x = 200; var size_y = 200; var scale_x =1; var scale_y =1; var surface = new imagesurface({   size: [size_x, size_y],   content: 'img/1.jpg',   properties: {     backgroundcolor: 'rgba(200, 200, 200, 0.5)',     cursor: 'pointer'   } }); var draggable = new draggable({   xrange: [-100, 1000],   yrange: [-100, 1000] }); surface.pipe(draggable); var mod = new statemodifier({   transform: transform.translate(150, 100, 0) }); var mod1 = new statemodifier({  }); maincontext.add(mod).add(mod1).add(surface); draggable.on('update',function(data){   var delta = draggable.getposition();   var scale_x = (size_x+ delta[0])/size_x;   var scale_y = (size_y+ delta[1])/size_y;   mod1.settransform(   transform.scale(scale_x,scale_y, 0)   ); });  });

all need change how using scale function. scaling 'z' property 0. should 1.

so change this..

transform.scale(scale_x,scale_y, 0);

to this..

transform.scale(scale_x,scale_y, 1);

good luck!
