1.
   簡易點及滑鼠繪圖 (無粗細顏色)
void setup()
{
  size(600,600);
  background(#FFFFFF);
}
void draw()
{
  if(mousePressed)
  line(mouseX,mouseY,pmouseX,pmouseY);
}

2.

 新增建盤選色

void keyPressed()

{

  if(key=='0') background(255);

  if(key=='1') stroke(#FF0900);

  if(key=='2') stroke(#FF9100);

  if(key=='3') stroke(#1CFF00);

}

3.

增加滾輪改粗細

int now=1;

void mouseWheel(MouseEvent event) {

  float e = event.getCount();

  now += e;

  if(now<1) now=1;

  strokeWeight(now);

  println(now);

}

4.

新增可儲存開啟檔案

if(key=='s') save("now.png");

  if(key=='r')

  {

    PImage img=loadImage("now.png");

    if(img!=null) image(img,0,0);

  }

5.

新增可開啟colormap 不影響原本的繪圖

if(key=='c' && bColorSelect==false)

  {

    bColorSelect=true;

    save("beforColor.png");

    PImage img=loadImage("colormap.png");

    image(img,0,0);

  }

  else if(key=='c' && bColorSelect==true)

  {

    bColorSelect=false;

    PImage img=loadImage("beforColor.png");

    if(img!=null) image(img,0,0);

  }

6.

  新增偷顏色

if(bColorSelect)

  {

    loadPixels();

    stroke(pixels[mouseX+mouseY*width]);

  }
