[Musickit-users] SndView Vertical (amplitude) Axis, Colors

[John R. <jri...@cs...>]

Hi There,

I am now successfully importing 16-bit mono sound from a quicktime movie
into a Snd, and displaying the sound in a SndView.

The vertical (amplitude) scale is rather small, however - with a view
completely "zoomed out", the waveform plot only takes up the middle 1/3
of the window - that is to say, the top 1/3 and bottom 1/3 of the view
are completely empty.  The documentation I've run across says that the
amplitude is automatically scaled when the SndView's Snd is set.  Is
there some way to explicitly scale the y axis?  Is there a way to
determine what the scale is set to?

On an unrelated note, the default colors are purple-on-black, which
doesn't quite match my color scheme.  I can see that SndView Class has
background and foreground values - but I can't find any methods to set
them.

Thanks in advance for any help,
John Rieffel
