松哥带你生成像素风格图像（像素风证件照也是没问题滴~）

from PIL import Imagedef init():
  # 设置每个像素区块的大小
  block_size = 75
  img = Image.open("bao5.jpg")  # 获取图片的宽高
  width, height = img.size  # 获取像素点对应RGB颜色值，可以改变img_array中的值来改变颜色值
  img_array = img.load()  # 为了处理最后的区块，加了一次循环
  max_width = width + block_size
  max_height = height + block_size  for x in range(block_size - 1, max_width, block_size):    for y in range(block_size - 1, max_height, block_size):      # 如果是最后一次循环，则x坐标等于width - 1
      if x == max_width - max_width % block_size - 1:
        x = width - 1
      # 如果是最后一次循环，则x坐标等于height - 1
      if y == max_height - max_height % block_size - 1:
        y = height - 1
      # 改变每个区块的颜色值
      change_block(x, y, block_size, img_array)
      y += block_size
    x += block_size
  img.save(r'result_3.jpg')
  img.show()"""
