PIL库是一个支持图像存储、显示和处理的函数库,它能够处理几乎所有图像格式,可以完成对图像的缩放、裁剪、叠加以及图像添加条纹,文字等信息等的操作。
首先是利用pip下载一个:
它有许多子库,例如:Image、ImageChops、ImageDraw等等,他们各有神通,发挥着自己的作用,
首先我们当然学习的是经典的Image子库:
方法 | 描述 |
Image.open(filename) | 根据参数加载图像文件 |
Image.new(mode,size,color) | 根据给定参数创建一个新的图像 |
Image.frombytes(mode,size,data) | 根据像素点data创建图像 |
Image.verify() | 对图像文件完整性进行检查,返回异常 |
图像可视化:
from PIL import Image im = Image.open("C:\\Users\\ZK\\Desktop\\test1.jpg") # 读取图片 im.show() # 可视化
效果如下:
灰度化h
灰度化:
from PIL import Image img = Image.open("C:\\Users\\ZK\\Desktop\\test2.jpg") # 灰度化:将RGB/RGBA -> L img = img.convert("L") img.show()
原图:
效果如下:
