I’m trying to sync the position of a Konva Line with the coordinates of a polygon that defines a Line for each segment of the poly. I want to enable drag resize along those line segments.

I’d like to add new Rectangle to a Stage, when the width and the height in a form is submitted.
The addition works fine, however, the selection has a large offset, but do not understand why.
The selection is fixed when the rectangle is resized, so it must be an issue with my onSelect call.
I used the Transformer – rectangle resize – demo as a baseline.

I would like to capture a stream from a Konva Stage.
