Python PIL | ImageOps.fit() 方法

PIL 是Python Imaging Library，它为Python解释器提供了图像编辑功能。 ImageOps 模块包含许多“现成的”图像处理操作。这个模块有点实验性，大多数运算符只处理 L 和 RGB 图像。

ImageOps.fit()方法返回图像的大小和裁剪版本，裁剪为请求的纵横比和大小。

Syntax: PIL.ImageOps.fit(image, size, method=0, bleed=0.0, centering=(0.5, 0.5))

Parameters:
image – The image to size and crop.
size – The requested output size in pixels, given as a (width, height) tuple.
method – What resampling method to use. Default is PIL.Image.NEAREST.
bleed – Remove a border around the outside of the image from all four edges.
centering – Control the cropping position.

• Use (0.5, 0.5) for center cropping (e.g. if cropping the width, take 50% off of the left side, and therefore 50% off the right side).
• (0.0, 0.0) will crop from the top left corner (i.e. if cropping the width, take all of the crop off of the right side, and if cropping the height, take all of it off the bottom).
• (1.0, 0.0) will crop from the bottom left corner, etc. (i.e. if cropping the width, take all of the crop off the left side, and if cropping the height take none from the top, and therefore all off the bottom).

Returns: An image.

使用的图像：

# Importing Image and ImageOps module from PIL package
from PIL import Image, ImageOps
  
# creating a image1 object
im1 = Image.open(r"C:\Users\System-Pc\Desktop\circleimage.PNG")
  
# applying fit method
# Setting width = 100 and height = 100
im2 = ImageOps.fit(im1, (100, 100), method = 0,
                   bleed = 0.0, centering =(0.5, 0.5))
  
im2.show()

输出：
