案例代码如下：

import java.util.Calendar;
boolean savePDF=false;
int tileCountX =2; //jianbianshuliang
int tileCountY=10;//hangshu
color\[\] colorsLeft =new colortileCountY;

color\[\] colors;
boolean interpolateShortest = true;//yansemoshikongzhi
void setup(){

noStroke();
shakeColors();//suijichanshengmeihangdezuoyoubianyanse
}
void draw(){
if(savePDF){
beginRecord(PDF,timestamp()+".pdf");
noStroke();

}
tileCountX=(int) map(mouseX,0,width,2,100);//map:yingshe

}
} if(savePDF){

endRecord();
}
}
void shakeColors(){

}

}
void keyReleased(){

if(key=='s'||key=='S')saveFrame(timestamp()+"_##.png");
if(key=='p'||key=='P')savePDF=true;

}
String timestamp(){

return String.format("%1ty%1tm%1td_%1tH%1tM%1tyS",now);
}
