I like map links. I like how now one can select the start / end of the link and bind it to top / bottom / left / right of notes. But sometimes a bit more manual control would be helpful, like when we want to keep notes perfectly aligned. Something like this:
(KEEP THE SOUND OFF. YOU HAVE BEEN WARNED).
Right now I’m using a hidden note (0 $Width and $Height) to make 2 step link. But it’s cumbersome… (see image)
Note, that in this case, OmniGraffle considers the line to always extend from center of one figure to center of the other, and only displays the “visible” portion of the line. Perhaps this would make simpler the programmatic calculations needed when moving a note.
BTW, if you have OmniGraffle or similar, you can use figures like the one illustrated in the GIF as image adornments and take advantage of the graphics
On the Add Midpoint proposal, does anyone happen to understand just what’s going on here?
I assume that we’re splitting the quaternary Bezier curve into two separate Bezier curves, and adding a constraint that the endpoints and slopes match where the two curves join.
It seems to me that we’d need one more constraint to actually define the curve. What is it?
I’ve never coded this myself, but I’m aware of a body of algorithm literature on the topic of midpoint bezier construction. For example
Since he tends to use existing libraries for his work, George Browning at Zengobi might be a resource for what’s available. Or the folks at Omni Group.
Bezier may take a while to implement (I guess). I wouldn’t mind having sonething like straight lines and break points like yEd Graph Editor has, if I could have them next week
We already have Bezier curves, actually. We currently choose the control points automatically; what were discussing is a way to manually change the control points, and/or to break a Bezier curve into two separate, but cleanly joined, segments.
