我们利用处理PNG图片是，可能需要获取基本的图片信息来做一些基本的处理，话不多说，上代码。
from PIL import Imageimg = Image.open("more.png")
# img.show()print(img.size)#获取图片大小（width， height）
print(img.size[0], img.size[1]) #（width， height）
print(img.mode)#获取图片模式{'1':1, 'L':8, 'P':8(带颜色表), 'RGB':24, 'RGBA':32,}
print(img.info) #打印的信息类似下方注释，当然必须图片内部包含该信息才行
