Hello,

Here I am again. I've got a little problem. I've got the following idea: I want that processing makes a picture (of your shadow which is projected on a white wall), saves it in the data directory, put it back into processing with a blendmode (the white wall will be subtracted, and only your silhouette will be displayed) and BEHIND this silhouette I want to play a video.

But the problem is that the picture from the silhouette is been shown behind the video, instead of the silhoutte in front of the video.

a = a white background
b = the picture which is made with the webcam

This is the code till now:

___________________________________________________________________


import processing.video.*;

Capture myCapture;

PImage a, b;

Movie theMov;

void setup() {
  size(640, 480, P2D);


  a = loadImage("bg3.jpg");
  b = loadImage("plaatje.jpg");
  theMov = new Movie(this, "film.mov");

 
  {myCapture = new Capture(this, width, height, 30);
  }
 
}

void captureEvent (Capture myCapture) {
myCapture.read ();

}

void draw() {

image(theMov,0,0);
 
}

void movieEvent(Movie m) {
  m.read();
}



void mousePressed() {
   image(myCapture, 0, 0);
   saveFrame("data/plaatje.jpg");
   delay(300);
   myCapture.stop();
  
  image(theMov,0,0);
   theMov.play();
   aplhaImage(); 
}

void aplhaImage(){
  for (int i = 0; i < 4; i = i+1) {
  blend(b, 0, 0, 640, 480, 0, 0, 640, 480, MULTIPLY);
}
 
}
