@zhe-he Thanks for your snippet, very helpful for me. Also, do you know how to keep the original width/height of the rectangle? Because right now, if a 100x100px rectangle has a 10px stroke, it is drawn 110x110px

Here is the complete version.

Fabric currently defaults to a center stroke side for outlines which is not configurable, and the calculation of an object's bounds includes the stroke width. To support different types of stroke side, it would be necessary to override Fabric's method for calculating an object's bounds, such that the bounds do not include the stroke width. Currently, Fabric draws strokes and fills simultaneously; to support different stroke side types, they would need to be drawn separately. The complete example includes detailed code.
