proce55ing/retinaImage and differenceImage and adaptivity

What this?

• JMyronライブラリのretinaImage(), differenceImage(), adaptivity(int value), adapt(), あたりの関数が理解しにくいかったので、サンプルを組んでみました。
• キーボードからadaptivityを変えれるようにしてありますので、適当に弄りながら、だいたいの感覚をつかんでください。
  • a : adaptivity を１上げる
  • z : adaptivity を１下げる
    
    

ScreenShots

• 上が retinaImage() で、下が differenceImage() です。
• adaptibity(20) だとこんな感じ
  
  
  
• adaptibity(5) だとこんな感じ
