How to access image that was dragged into DKDrawingView[Help Needed] about drawkit HOT 4 CLOSED

Please could you add screenshots to show the behaviour and another for the desired output?

from drawkit.

when i drag in a very large photo

i'd like to be able to auto scale the photo to fit the dkdrawingview.

it appears from the demo this functionality is in DKImageShape class but i'm not sure how to derive these functions from the layer/object that was just added. currently i'm using hit test to get the object that was added but this is not right .
var canvasDrawing:DKDrawing!
.
.
let obj = canvasDrawing.objectInLayers(at: 1)
let drawableObj = obj.hitTest(NSPoint.init(x: 100.0, y: 100.0))
drawableObj?.resizeBy(width: 0.1, height: 0.1)

so i need some kind of delegate method that is called when an object is dropped into the view. i'm already implementing DKDrawingDelegate methods, but i don't think any of these notify when an object is added. then i need to reference that object some way other than using hittest

I am unsure of the best approach because I have not used DrawKit for a while.

However, I suspect a reasonable approach is to use Key Value Observation (KVO) of the drawing layer's objects. The observer is then notified when an object is added. From there you can access the object and resize it according the parent DrawingView's size.

Does this make sense?

Awesome. Thank you!
