When I move resegmentation handle, straight lines are removed. But if I move reshaping handle, straight lines are sometimes remain.
See this video from the sample page:
I expect straight line to be removed at 0:08 point in the video when I move the top handle, as the same line is removed at 0:12 point after moving the bottom handle.
In my project it reproduces with 3.0.27 version, Orthogonal routing and go.LinkReshapingTool.
Yes, that is intentional – only resegmenting handles might increase the number of segments.
The problem is not with increasing the number of segments. It is with the way LinkReshapingTool removes unneded segments. If resegmentingDistance is set it removes segments that form a straight line.
But in the video you can see that it does that only when moving one points, but not the others. I move reshaping handles in both scenarios and produce the same end result at 0:08 and at 0:12, but in one case segment is removed (0:12, bottom handle), and in another one it stays (0:08, top handle).
I expect the behavior to be the same in both scenarios and the segment to be removed.
I had originally written that only the resegmenting handles change the number of segments, but that’s clearly not true when reshapable is true and dragging a reshaping handle – the number of segments may decrease then. So I changed what I wrote to say that dragging a resegmenting handle may increase the number of segments, implying that dragging either a reshaping or a resegmenting handle may decrease the number of segments.
I suppose the LinkReshapingTool could be smarter, but it isn’t at the moment. I’m working on the other problem, involving inserting a lot of points.
Got it, thanks for the explanation. For now I’m cleaning up those points in my custom SnapLinkReshapingTool’s doDeactivate. Would be nice to have this built-in in the future.
