Simply repositioning a waveform
Jun 5th, 2010, 6:08am  
I am trying to move the waveform to another location on screen. It seems simple however i've tried and failed. Please help me  Embarrassed

void draw()
{
 background(0);
 stroke(255);
 // draw the waveforms
 // the values returned by left.get() and right.get() will be between -1 and 1,
 // so we need to scale them up to see the waveform
 // note that if the file is MONO, left.get() and right.get() will return the same value
 for(int i = 0; i < bgmusic.left.size()-1; i++)
 {
  line(i, 50+ bgmusic.left.get(i)*50, i+1, 50 + bgmusic.left.get(i+1)*50);
   line(i, 150 + bgmusic.right.get(i)*50, i+1, 150 + bgmusic.right.get(i+1)*50);
   
 }
}

you can use translate
http://processing.org/reference/translate_.html to move it arround. be sure to use pushMatrix() and popMatrix() if you draw other stuff that shouldnt be translated
