到https://gdms.cwa.gov.tw/>資料下載>選

選測站

利用資料做出像地震觀測的結果

float [] HLE = {-1042, -3479.7, 1003.7, -1669, -1639.6, -14219, -3655.1, -4917, 9363.2, -4271.8, -24, 681
};
int N = 12;
void setup(){
  size(500,500);
}
void draw(){
  background(#FFFFF2);
  float dx = HLE[frameCount%N]/100;
  rect(200+dx,300+dy,100,100);
}

step02
下載一張圖片，拉進processing
PImage img = loadImage("chair.jpg");
size(300,300);
image(img,0,0);
顯示圖片




















PImage img = loadImage("chair.jpg");
size(300,300);
image(img,0,0,300,300);
符合圖片大小

PImage img;
void setup(){
  size(600,600);
  img = loadImage("chair.jpg");
}

void draw(){
  image(img,mouseX,mouseY,300,300);
}
圖片當成畫筆

PImage img, imgBox;
void setup(){
  size(600,600);
  img = loadImage("cindy.png");
  imgBox = loadImage("box.png");
}

void draw(){
  imageMode(CENTER);
  if(mousePressed){
    image(imgBox,mouseX,mouseY);
  }
  else{
    image(img,300,300,220,300);
  }
}

用視窗畫出階梯的感覺 imgBox
