边学边练，直接上代码

RUBY 代码


简单的测试，希望可以回复一下次数

RUBY 代码
[code]src = Bitmap.new(640, 480)  # 观看效果的话，换成图片，注释掉下面一行代码
src.fill_rect(src.rect, Color.new(0, 255, 255))
dst = src.clone
sprite = Sprite.new
sprite.bitmap = dst


count, t = 0, Time.now
loopdo
  dst.main_blur!(1)
  breakifTime.now - t >= 1.0
  count += 1
end
str = "blur => #{count}次/秒\n"  # 195次/秒……

count, t = 0, Time.now
loopdo
  dst.expBlur!(2, 16, 7)
  breakifTime.now - t >= 1.0
  count += 1
end
str = 1.0
  count += 1
end
str = 1.0
  count += 1
