急！！！导出pdf有问题！！！

[xurenfang]

2个小程序想导出pdf，无奈都报错。一个是颜色不对，提示light()函数不适应，另一个直接translate()不适应，画面一片黑。据哪位大侠能帮忙看下。。
人像程序

程序代码

import processing.opengl.*;

import processing.pdf.*;



PImage img;       
int cellsize = 2; 
float yOffset;
boolean recordOrNot = false;

void setup() {

  size(500, 600, P3D);

  frameRate(30);
  smooth();
  imageMode(CENTER);
  zOffset=0;



  img = loadImage( "1230.jpg" );
}

void draw() {

  if (recordOrNot) {
    beginRecord(PDF, "Output.pdf");
  }
  background(0);
  img.loadPixels();

  for (int i = 0; i < width/2; i++ ) {

    for (int j = 0; j < height/2; j++ ) {


      int x = i*2 + 1; 
      int y = j*2 + 1; 

      int loc = x + y*width;          
      color c = img.pixels[loc];       
      float z = zOffset * brightness(color(c));


      pushMatrix();
      translate(x, y, z); 
      stroke(c);
      point(0, 0);

      popMatrix();
    }
  }

  zOffset+=0.005;


  if (recordOrNot) {
    endRecord();
    recordOrNot = false;
  }
}

void mousePressed() {
  recordOrNot = true;
}

圆圈程序

程序代码

}

    noStroke();
    fill(random(100), 360, 255);
    c=noise(cSeed);
    cSeed+=1;
    pushMatrix();
  
    
  
   translate(cos (a)*r,sin( a)*r ); 
a= degrees((i+1)*19);
