BPF-Lib / BPC-Lib Editors

All the information provided in the BPF and BPC Editor section also apply to BPF-lib and BPC-lib editors.

Editing Curves

Items Selection

All editing operations can be performed upon one curve only. Edition procedures are similar to those used in BPF or BPC editors.

To switch from a curve to another, press the TAB key.

The selected curve is displayed in the foreground. Its name or index appears at the top of the editor.
The other curves are displayed in the background with dashed lines.

To show or hide background curves, select or unselect the Background option.

Adding Curves in BPF-lib or BPC-lib Editors

Adding BPFs

To add a curve in a BPF-lib editor :

select the pointer tool.
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.
To edit the new curve, Cmd click in the editor to add a first point in it.

Hidden Curve

If you haven't edited the first curve, 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 each new BPC visible.

To add a second BPC :
1. SHIFT + Cmd click outside the line to switch the first curve to the background.
2. Cmd click twice in the editor to add the new curve.
