Resize Mode

Resize Mode controls what happens when you change the size of the canvas.

With Recalculate Coding, changing the canvas size changes the number of bights and parts in the knot. In this mode, the size fields are read-only.

With Stretch Grid, changing the size of the canvas changes the distance between nodes without changing the number of bights and parts. In this mode, the size fields are live inputs.

Switch on Options > Image & Canvas: Show Grid Boundary to see the size area.
