image.crop是Python中用于裁剪图片的函数。在使用该函数前,我们需要先导入PIL库,即Python Image Library。from PIL import Image # 打开图片 img = Image.open('example.jpg') # 图片的裁剪区域(区域左上角的坐标为(100, 100),右下角的坐标为(300, 300)) crop_area = (100, 100, 300, 300) # 裁剪并...

im = Image.new('RGBA',(200,200),'white') #Image.new函数新建一个图像,参数含义(颜色模式,图像大小(元组表示),背景色) 1. faceim = catlmg2.crop((335,345,565,560)) #crop函数裁切图像并返回一个新的Image对象,矩形元组(左[,上[,右),下)) 1. catlmg2 = catlmg.copy() #copy函数复制图像,...
box = (100, 100, 400, 400) region = im.crop(box)区域由一个4元组定义，表示为坐标是 (left, upper, right, lower)。 Python Imaging Library 使用左上角为 (0, 0)的坐标系统。同时要注意，这些坐标指向像素之间的位置，因此上述例子中描述的区域的大小为300x300像素。后两个数字需要比...
SystemError: tile cannot extend outside image 意思就是超限了,裁剪参数超出边缘了。 这里就说明了BOX里面四个参数的不是单纯的裁剪边缘距离。 而是: left:左边裁剪起始位置 upper:上边裁剪起始位置 right:需要裁剪多大像素,从左边起始位置开始算起,所以这个数值必须大于left,否则会报错。因为真正裁剪的宽尺寸是:righ...

For high-volume operations, automate batch-processing of image crops using APIs and pre-configured parameters. This ensures consistency and reduces the likelihood of errors when scaling image transformations across thousands of assets. Implement quality assurance checks by sampling and reviewing a ...
