hi there,

i am trying to do the following:

i want to have three slideshows (with the same pcitures) on one stage.

on keypress (or mousepress) the first one starts. on the next keypress it stops at the current picture and triggers the next one to begin. next keypress this one pauses, third one begins.

so in the end i have three pictures. i would export that as jpg and start again.

i tried to come up with something using the "Slide_show_with_one_PImage" technique, but it doesnt really work.
the second and the third slideshow do not work:
1. PImage img;
  String[] files;
  int timer;
  int nextimg;
  
  PImage img2;
  String[] files2;
  int timer2;
  int nextimg2;
  
  PImage img3;
  String[] files3;
  int timer3;
  int nextimg3;
  
  int a=1;
  
  void setup() {
  size(1754,1240);
  
  files=new String[3]; //some example images.
  files[0]="medium.jpg";
  files[1]="small.jpg";
  files[2]="big.jpg";
  
  nextimg=(nextimg+1)%files.length;
  img=loadImage(files[nextimg]);
  timer=0;
  
  //next slideshow
  
  files2=new String[3]; //some example images.
  files2[0]="medium.jpg";
  files2[1]="small.jpg";
  files2[2]="big.jpg";
  
  nextimg2=(nextimg2+1)%files2.length;
  img2=loadImage(files2[nextimg2]);
  timer2=0;
  
  //next slideshow
  
      files3=new String[3]; //some example images.
  files3[0]="medium.jpg";
  files3[1]="small.jpg";
  files3[2]="big.jpg";
  
  nextimg3=(nextimg3+1)%files3.length;
  img3=loadImage(files3[nextimg3]);
  timer3=0;
  
  }
  
  void draw() {
  
  if(a==1){
  
  if(timer==0)
  {
      background(255);
      image(img,30,30);
  }
  else if(timer==1)
  {
      img=loadImage(files[nextimg]);
      nextimg=(nextimg+1)%files.length;
      delay(50); //this decides how long an image should be displayed
  }
  timer=(timer+1)%2;
  }
  if(a==2){
  
      if(timer2==0)
  {
      background(255);
      image(img2,500,500);
  }
  else if(timer2==1)
  {
      img=loadImage(files2[nextimg2]);
      nextimg2=(nextimg2+1)%files2.length;
      delay(50); //this decides how long an image should be displayed
  }
  timer2=(timer2+1)%2;
  }
  
  if(a==3){
  
      if(timer3==0)
  {
      background(255);
      image(img3,1000,500);
  }
  else if(timer3==1)
  {
      img=loadImage(files3[nextimg3]);
      nextimg3=(nextimg3+1)%files2.length;
      delay(50); //this decides how long an image should be displayed
  }
  timer3=(timer3+1)%2;
  }
  
  }
  
  void mousePressed() {
  if(a<3){
      a=a+1;
      }
      else {
      a=1;
      }
  }
i think its not a good piece of code at all, and propably the wrong start, but i'm still pretty new to processing...

thank you very much in advance!

or am i just plain stupid and it is pretty simple?

thank you very much in advance,

hi everybody,

i'm pretty new to processing and i wonder wether processing is the right thing for my project or not.

i need a program that randomly loads a picture (from about 2000 images) and sends it to an actual printer and never loads that picture again.

but printing is not that easy in processing?

what do you think?

and if processing is right, where should i start?

(i dont want any complete code from you, but i need a starting point...)

thank you,
mpod
