Save Waveform As…
Use the Save Waveform As… command the first time you save your
waveform. It will let you select name, location and format for your
waveform file.
With this command you may print the active Waveform Window. The
standard printer dialog box will appear and will let you select printer
setup, or print the waveform page.
Exit
The Exit command ends the current Wave Composer session and
takes you back to the Panels screen. If you made changes to your
waveform since it was last saved, the Wave Composer will prompt you
to Save or Abandon changes these changes.
Edit Commands
The Edit commands are used for manipulating the waveform that is
drawn on the screen. The editing commands are explained in the
following paragraphs.
Autoline
The Autoline command lets you draw straight-line segments. To draw
a line the left mouse button at the start point. Click again at the next
point and then click on the right mouse button to terminate this
operation.
Sketch
The Sketch command lets you draw free-hand segments. To draw a
line using this command click and hold the left mouse button at the
start point. Release the mouse button when you want to stop and then
click on the right mouse button to terminate this operation.
Smooth
The Smooth command lets you smooth out rough transitions on your
waveform. This is done mathematically by multiplying waveform
coordinates by the non-linear portion of a cubic parabola.
The Smooth operation is done on segments of the waveform that are
bound by anchors. Anchor operation is described later in this chapter.
Place the anchors on the left and right of your waveform segment and
select the Smooth command. The waveform will change its shape
immediately to follow the mathematical pattern of a parabolic curve.
Note that small segments with fast transitions, when combined with
parabolic expressions have tendencies to generate even larger
transitions. Therefore, make sure you omit such sections of the
waveform when you use this operation.
