I want to make somekind of "screenshots" and export them as PDF, in order to map them in another step on a shape.

here you can see the code of a pattern i made and try to export those frames i choose by Mouse pressed.

It would be great if someone could help! Thank you(i work with processing 1.5)

import processing.pdf.*;

import processing.opengl.*;

int anzahl = 3;
float[] x = new float[anzahl];
float[] y = new float[anzahl];
float[] z = new float[anzahl];
float[] speedX  = new float[anzahl];
float[] speedY = new float[anzahl];
float[] speedZ = new float[anzahl];


// A boolean variable that when set to true triggers the PDF recording process
boolean recordPDF = false;

void setup() {
  // OPENGL or P3D mode requires the use of beginRaw() and endRaw() instead of beginRecord() and endRecord().
  size(400, 400, OPENGL);
  smooth();
 
  for(int i = 0; i<anzahl;i++){
x[i] = random(100,300);
y[i] = random(100,300);
z[i] = random(100,300);
speedX[i] = random(0.1,2);
speedY[i] = random(0.1,2);
speedZ[i] = random(0.1,2);
}
}

void draw() {
  // Begin making the PDF
  if (recordPDF) {
    beginRaw(PDF, "3D.pdf" ); // If you include "####" in the filename -- "3D-####.pdf" -- separate, numbered PDFs will be made for each frame that is rendered.
  }
 
 

//background(120);

for(int i = 0; i<anzahl;i++){
x[i] = x[i]+speedX[i];
y[i] = y[i]+speedY[i];

for(int j = 0; j<anzahl;j++){
float d = dist(x[i],y[i],x[j],y[j]);
if(d<150){
stroke(0,map(d,350,350,455,0)/5);
triangle(x[i],y[i],x[j],y[j],x[i],y[j]);

}
}



 
if(x[i]>width)speedX[i] = speedX[i]*-1;
if(x[i]<0)speedX[i] = speedX[i]*-1;
if(y[i]>height)speedY[i] = speedY[i]*-1;
if(y[i]<0)speedY[i] = speedY[i]*-1;

  // End making the PDF
  if (recordPDF) {
    endRaw();
    recordPDF = false;
  }
}

// Make the PDF when the mouse is pressed-this is the line i get the"unexpected token"
void mousePressed() {
  recordPDF = true;
}
}
}
