像素头像生成 图片像素化 CryptoPunks头像生成

[python]代码库

from PIL import Image
import collections

pic = Image.open("img.png").convert("RGB")
width, height = pic.size
block = 10  # 小格子大小，数字越大像素粒越大

board = Image.new("RGB", (width // block * block, height // block * block))  # 新图片宽高取整
for y in range(0, height, block):  # 行
    for x in range(0, width, block):  # 列
        temp = pic.crop((x, y, x + block, y + block))  # 截取block * block区块图像
        temp_list = list(temp.getdata())  # 获取像素序列并转为普通序列
        max_color = collections.Counter(temp_list).most_common()[0][0]  # 计算像素块颜色，取最多出现的一个颜色
        temp_past = Image.new("RGB", (block - 1, block - 1), max_color)  
        #temp_past = Image.new("RGB", (block, block), max_color) # 像素块无边框
        board.paste(temp_past, (x, y))
        x = x + block  # 跳过
    y = y + block  # 跳过
board.show()
