Adding Curves in BPF-lib or BPC-lib Editors

Adding BPFs

To add a curve in a BPF-lib editor :

  1. select the pointer tool.

  2. SHIFT + Cmd click in the editor.

    • The existing curve(s) switch to the background and are displayed with dashes.
    • The new curve is at the foreground.
  3. To edit the new curve, Cmd click in the editor to add a first point in it.

Hidden Curve

If previous curve hasn't been edited, the new curve is superimposed to it at the foreground. To visualize the new curve, select the curve tool and move the line.

Adding BPCs

Contrary to BPFs, which initially come with two default points, BPCs come empty.

  • To add a first BPC :

    Select the pointer and Cmd click twice in the editor to create a curve. Two points at least must be added in the editor to make a new BPC visible.

  • To add other BPCs :

    1. SHIFT + Cmd click outside the line to create a new empty curve. The previous ones go to the background.

    2. Cmd click twice in the editor to add points to the curve.
