text popup

sansfordpete

hey guys, I know its really simple but I was wondering why my text doesn't show up in the display, my images show but my text doesn't. also I wanted to know what else I could do to improve my code. here it is:

import ddf.minim.spi.*;
import ddf.minim.signals.*;
import ddf.minim.*;
import ddf.minim.analysis.*;
import ddf.minim.ugens.*;
import ddf.minim.effects.*;

Minim minim;
//this is the audio signal that the program will output
AudioOutput sineout;
SineWave sine;
LowPassSP lpf;
HighPassSP hpf;
BandPass bpf;
PImage img1;
PImage img2;
PImage img3;
boolean dispimg1;
boolean dispimg2;
boolean dispimg3;

void setup(){
  size(500,500);
  img1 = loadImage("LPF.png");
  img2 = loadImage("HPF.png");
  img3 = loadImage("BPF.png");
  minim = new Minim(this);
  sineout = minim.getLineOut();
  sine = new SineWave(500, 1, 44100);
  lpf = new LowPassSP(325, 44100);
  hpf = new HighPassSP(550, 44100);
  bpf = new BandPass(350, 200, 44100);
  sineout.addSignal(sine);
}

void draw(){
  background(200);
  for(int i= 0; i < sineout.bufferSize() - 1; i++){
    stroke(#F20C0C);
    line(i, 300 + sineout.left.get(i)*20, i+1, 300 + sineout.left.get(i+1)*20);
  }
  if(dispimg1){
    fill(0, 40, 60);
    text("low pass filter", width/2, 30);
    image(img1, width/2, height/2);
  }
  if(dispimg2){
    fill(0, 40, 60);
    text("high pass filter", width/2, height/2+30);
    image(img2, width/2, height/2);
  }
  if(dispimg3){
    fill(0, 40, 60);
    text("band pass filter", width/2, height/2+30);
    image(img3, width/2, height/2);
  }
}
void mouseMoved() {
  sine.setFreq(220+mouseX);
  sine.setFreq(150+mouseY);
}

void keyPressed(){
  if (key == 'q') {
    toggleEffect(lpf);
    dispimg1 = true;
    dispimg2 = false;
    dispimg3 = false;
   // image(img1, width/2, height/2);
  }
  else if (key == 'w'){
    toggleEffect(hpf);
    dispimg2 = true;
    dispimg1 = false;
    dispimg3 = false;
   // image(img2, width/2, height/2);
  }
  else if (key == 'e'){
    toggleEffect(bpf);
    dispimg3 = true;
    dispimg1 = false;
    dispimg2 = false;
   // image(img3, width/2, height/2);
  }
}

void toggleEffect(AudioEffect effect){
  if (sineout.hasEffect(effect)){
    sineout.removeEffect(effect);
  } else {
    sineout.addEffect(effect);
  }
}

help would be greatly appreciated

It depends on the size of the images, but apparently you first draw text, then you draw image over it... Invert the order of the calls.
