width: Output picture widths height
: output Picture Heights
Type: Output picture types (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 =
  type = ' png '
  resizeimage (Filein, fileout, width, height, type)
