hey! i got this code and i wanted to export a pdf but the problem is, when ever i open the PDF in acrobat it says that i the file has an error.

here's my code... am i doing something wrong in my export?

Code:

import processing.pdf.*;



color[] mycolours = {
 // color(215,161,44),color(11,17,3),color(32,75,8),color(86,138,20),color(56,108,12),color(247,94,43),color(150,105,17),color(44,45,9),color(236,59,25),color(246,130,49),color(114,59,13),color(97,100,25),color(146,133,23),color(127,160,40),color(173,70,16),color(203,90,27)};
    color(190,193,208),color(133,55,21),color(50,79,139),color(28,17,70),color(103,136,181),color(211,137,71)};
    String[] shapeNames = { "A.svg" , "B.svg"};
	PShape[] shapes;
	
	int num = 1;

void setup(){
  
  
  //---------------------
  size(800,600);
  smooth();
  background(255);
//_____________________________
 
     shapes = new PShape[shapeNames.length];
  for (int s = 0; s < shapes.length; s++)

 shapes[s] = loadShape(shapeNames[s]);
 

  //______________________________________ 
    
}


void draw(){
		beginRecord(PDF, "grid_7_"+ num + ".pdf");
  float rot=random(10);
  //rotate(rot);
  noStroke();
	  


  //translate(10,10);



 
  for(int i = 0 ;i < 800; i = i+20){
    for(int j = 0 ;j < 600; j= j+20){

    PShape shapeToDraw = shapes[int(random(shapes.length))];
    scale(random(3));
    float trans = random(50,100);
    
	     shapeToDraw.disableStyle();  

	
	color cor2 = mycolours[int(random(mycolours.length))];
	color cor = mycolours[int(random(mycolours.length))];
	
	fill(cor2,trans);
	//strokeWeight(random(4));
	//stroke(cor);
	float rnd = random(4);

	shapeMode(CENTER);
	float xprop = shapeToDraw.width*rnd;
	float yprop = shapeToDraw.height*rnd;
	shape(shapeToDraw,i,j, xprop,yprop);
	//	   ellipse(i,j,10,10);

	noLoop();
	
    }
  }
}

void mousePressed(){
//  fill(255,100);
 // rect(-1,-1,width+1,height+1);
 background(255);
  redraw();
}

void keyPressed(){
 if(key=='s'){
   endRecord();
   num++;
   
 }
}

i've put them in this link so you can help me, thanks for the response btw

but i do! yesterday i made 500 pdfs lol and didn't opened them before I closed the sketch.... today I went to print them and there was an error, I thought it was a printer shop's error so i came home and the error existed in my pdf too

I had no problem to open the PDF exported by your program.
Perhaps you can sendthisfile one of such faulty PDF? I doubt I can tell much about it, but I am curious to see if I can open it as well.

Foxit Reader opens it without problem.
Adobe Reader 7 says: "Token type not recognized" and doesn't show the document.
Both on WinXP.
Ah, Adobe just asked if I want to upgrade to v.9.3. Let see...
Wow, 26MB! Talk about a lightweight application... I know why I use Foxit on most of the computers I use...
And it expects me to restart after install!

Anyway, Adobe Reader 9.3 doesn't complain about this file.

So, I think the issue is with the version tag of the file. If you open the file with a good text editor (preserving binary data...) or just an hex editor, you can see the first line of the file to be:
%PDF-1.4
Most PDF files I have have 1.3 or lower.
I suppose older versions of Adobe Reader doesn't handle this PDF version.
You have two solutions:
- Ask your printer shop to upgrade! (unlikely...)
- Use a good search/replace utility to change the above tag to 1.3. I guess the files doesn't actually use advanced feature, so the change should be safe.

I suppose we can ask iText (the Java library generating the PDF) to default output to a lower version but it needs investigation...
