RGB值转GIF# coding=UTF-8from PIL import Imagex = 1280 #x坐标 将RGB值的行数进行因式分解，得到x,y的值
y = 960 #y坐标imge = Image.new("RGB",(x,y)) #创建图片
file = open('D:\\ichunqiu\\item\\momo.txt') #打开RGB值的文件for i in range(0,x): #遍历for j in range(0,y):line = file.readline() #获取一行RGB的值rgb = line.split(",") #以逗号来分割RGBimge.putpixel((i,j),(int(rgb[0]),int(rgb[1]),int(rgb[2])))imge.show()

变换图片尺寸#coding = utf-8>>> import Image
>>> img = Image.open("test.jpg")
>>> x,y = img.size
>>> img.thumbnail((x//2,y//2)) #缩小百分之50
>>> img.save('test.jpg','jpeg') #以jpeg保存
提取RGB值#coding = utf-8from PIL import Imageimg = Image.open('test.jpg')
pix = img.load()
w = img.size[0]
h = img.size[1]
for x in range(w):for y in range(h):r, g, b = pix[x, y]
