7.9.1 Control Point Setting
Interpolation is executed for a range that is selected by markers in waveform display screen.
A control point can be set outside the selected range. However, control points outside the range are
ignored when interpolation is executed.
A control point may be set on any location. However, two or more control points cannot be set on one X
coordinate.
Specify a control point by values
Enter coordinate values in the input area on the right side of [X=] and [Y=] of [Interpolate Panel].
To activate the right side of [X=], click the input area, or press Alt + X.
To activate the right side of [Y=], click the input area, or press Alt + Y.
Click Add button to display the [+] mark at the specified position of the Waveform display section. The
positions of the control points are displayed also in the list of control points of [Interpolate Panel] using
their values. In the list of the control points, control points are displayed after sorted by the ascending
order of their X values.
Specify a control point by mouse
If any [+] mark of control points is shown if red (selected), first click in the waveform display area
where there is no mark displayed to change all marks to light blue (not selected).
Move the mouse cursor to the position to which you want to add a control point, and then click it while
pressing Ctrl key. A control point will be added. You can know approximate position of the mouse
cursor in [Cursor] on the top left of the Waveform display section. The added control point is also added
to the list of control points in the [Interpolate Panel]. Check the coordinate values.
Move a control point by values
When you select (click) any control point from the list of control points in the [Interpolate Panel], the
point is selected and the following processes are performed:
 The specified part of the list is displayed inverted.
 In the input area of [X=] and [Y=], the coordinate values of the selected control point are displayed.
 In the Waveform display section, the corresponding coordinate point [+] mark turns to red.
The control point can also be selected by clicking [+] mark in the Waveform display section. However,
if the magnification of the screen is lower, the mark may not be caught due to the screen resolution.
While a control point is selected, updating the value of [Y=] and clicking Add button moves the
selected control point. Clicking Add button after updating the value of [X=] adds a new control point if
the identical coordinate point does not exist, or updates the control point if exists.
Move a control point by mouse
A control point can also be moved by dragging [+] mark of the Waveform display section. However, if
the magnification of the screen is lower, the mark may not be caught due to the screen resolution.
