Python implements a way to change the size of a picture (based on the pillow package)

This example describes how Python implements changing the size of a picture. Share to everyone for your reference, as follows:

1, PIL package recommended pillow.

2. Source code:

#encoding =utf-8#author:walker#date:2014-05-15#function: Change the picture size import osimport os.pathfrom PIL import image ' Filein: Input image fileout: Output image width: Output image height: Output image altitude type: Output picture type (PNG, GIF, JPEG ...) "Def resizeimage (Filein, fileout, width, height, type):  img = Image.open (filein) out  = Img.resize ((width, Height), image.antialias) #resize Image with high-quality  out.save (fileout, type) if __name__ = = "__main__":  Filein = R ' image\test.png '  fileout = R ' image\testout.png '  width =  height = =  ' png '  Resizeimage (Filein, fileout, width, height, type)

I hope this article is helpful for Python program design.
