使用开放层3修改正方形和圆形

Question

I am new for Open layer and using open layer 3.I draw square on map using 4 coordinates. but now I want to edit that square by stretching any of one point but make sure it should not change shape of square(rectangle) to other shape.

Right now, I am using ol.interaction.Modify but it's modify only for Point , Linestring and Polygon .

How would I extent this to support modification of circle and square(rectangle)?

Answer 1

It depends what do you mean by modifying square. You can modify a rectangle with the modify.interaction but you can not reshape it. I guess you mean reshape and not just modify. If this is your case , ol3 does not support it out of the box. But here there is an extension to do the reshape for every possible geometry (rectangle, polygon etc.) I am not sure whether it supports circles.
