Python PIL |混合（）方法

PIL 是Python Imaging Library，它为Python解释器提供了图像编辑功能。 PIL.Image.blend()方法通过在两个输入图像之间插值，使用恒定的 alpha 创建一个新图像。

Syntax: PIL.Image.blend(image1, image2, alpha).

Parameter:
image1: first image
image2: second image, must have the same mode and size as the first image.
alpha: The interpolation alpha factor. If alpha is 0.0, a copy of the first image is returned. If alpha is 1.0, a copy of the second image is returned. There are no restrictions on the alpha value. If necessary, the result is clipped to fit into the allowed output range.

# Importing Image module from PIL package 
from PIL import Image
  
# creating a image1 object and convert it to mode 'P'
im1 = Image.open(r"C:\Users\sadow984\Desktop\i2.PNG").convert('L')
  
# creating a image2 object and convert it to mode 'P'
im2 = Image.open(r"C:\Users\sadow984\Desktop\c2.PNG").convert('L')
  
# alpha is 0.0, a copy of the first image is returned
im3 = Image.blend(im1, im2, 0.0)
  
# to show specified image 
im3.show()

输出：

# alpha is 1.0, a copy of the second image is returned
im3 = Image.blend(im1, im2, 0.0)
