Transition

You can provide a vue transition like this:

Vue.transition("fade",{
  // your transition
})
// or in the instance:
transitions: {
  fade: {
    // your transition
  }
}
// usage:
template: "<zoombox transition='fade'></zoombox>"

You can access several properties in your hooks:

enter: function(el,cb) {
  self = this
  this.nextTick(function(){
    self.imgScale // scale to get the small image size
    self.scale // multiply with imgScale to get the big image size
    // target top and left positions for big image size
    self.relPos.top
    self.relPos.left
    // starting position for top and left are 0
  })
}

Example from dev/basic.vue

Velocity = require("velocity-animate")

transitions:
  zoombox:
    css: false
    enter: (el,done) ->
      Velocity.hook(el, "scale", @imgScale)
      @$nextTick =>
        Velocity el, {scale:@imgScale*@scale,top:@relPos.top,left:@relPos.left}, {
          duration: 1000,
          queue: false,
          ease: "easeOutQuad",
          complete: done
        }
    leave: (el,done) ->
      Velocity.hook(el, "scale", @imgScale*@scale)
      Velocity el, {scale:@imgScale,top:0,left:0}, {
        duration: 1000,
        queue: false,
        ease: "easeOutQuad",
        complete: done
      }
