How to scale selected object without changing its current position?

[Bharat Patel]

Hi,

 

I am using 'selectionScaleX' & 'selectionScaleY' property to scale selected image.

 

_transformManager.selectionScaleX = 0.5

_transformManager.selectionScaleY = 0.5

 

However it change the image x and y position. 

 

Is is possible to scale selected image object without changing image position?

 

Thank You

Regards,

By its very nature, scaling must change the selected object's x/y position unless its registration point happens to line up directly on the overall selection's origin. If you'd like things to scale from the selection's center, you can certainly set the TransformManager's scaleFromCenter property to true. Does that help?

I tried the scaleFromCenter, it also update the object x/y position. In my case i am expecting scale should only perform with reference to top left point of transform.

 

is there any option through which we can set top left point as registration point?

There isn't a way to set a custom registration point, no. Sorry. You can certainly set the scaleX/scaleY of your element directly, though (not through TransformManager) and then updateSelection() if you'd like. Our tweening engine has a transformAroundPoint plugin that would allow you to scale a single target around a particular point, regardless of its registration point. The bigger challenge with TransformManager is that it accommodates multiple selections which could all be at different rotations/scales/positions (that makes it much more difficult).

I understand the challenge with TransformManager. I will handle it directly over element and after that 

_transformManager.updateSelection() 

With the alternate option will achieve my goal.

 

Thank for response.
