这篇文章主要介绍了python实现图片变亮或者变暗的方法,涉及Python中Image模块操作图片的相关技巧,分享给大家供大家参考。具体实现方法如下
import Image
# open an image file (.jpg or.png) you have in the working folder
im1 Image.open(angelababy.jpg)
# multiply each pixel by 0.9 (makes the image darker)
# works best with .jpg and .png files, darker 1.0 lighter
# (.bmp and .gif files give goofy results)
# note that lambda is akin to a one-line function
im2 im1.point(lambda p: p * 0.5)
# brings up the modified image in a viewer, simply saves the image as
# a bitmap to a temporary file and calls viewer associated with .bmp
# make certain you have associated an image viewer with this file type
im2.show()
# save modified image to working folder as Audi2.jpg
im2.save(angelababy2.jpg)
运行效果如下所示希望本文所述对大家的Python程序设计有所帮助。
