本文实例讲述了python实现图片变亮或者变暗的方法。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-600 or.png-600) you have in the working folder im1 = Image.open("angelababy.jpg-600") # multiply each pixel by 0.9 (makes the image darker) # works best with .jpg-600 and .png-600 files, darker <1.0 <lighter # (.bmp and .gif files give goofy resu来源gaodai#ma#com搞*!代#%^码网lts) note that lambda is akin to a one-line function im2=im1.point(lambda p: p * 0.5) brings up the modified image in viewer, simply saves as bitmap temporary file calls viewer associated with .bmp make certain you have an this type im2.show() save working folder audi2.jpg-600 im2.save("angelababy2.jpg-600")
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。
