pillow模块
图片处理
安装
pip install Pillow
对图片旋转90度显示
from PIL import Image im=Image.open("t.jpg") im.rotate(90).show()
对图片进行裁剪并保存
from PIL import Image import glob, os size = 128, 128 for infile in glob.glob("*.jpg"): file, ext = os.path.splitext(infile) im = Image.open(infile) im.thumbnail(size, Image.ANTIALIAS) im.save(file + ".thumbnail.jpg", "JPEG")
切割图片
from PIL import Image def fill_image(image): width, height = image.size # 选取长和宽中较大值作为新图片的边长 new_image_length = width if width > height else height # 生成新图片[白底],底色可配置其他颜色 new_image = Image.new(image.mode, (new_image_length, new_image_length), color='white') # 将之前的图片input image 粘贴在新图上,居中 if width > height: # 原图宽大于高,则填充图片的竖直维度 #(x,y)二元组表示粘贴上图相对下图的起始位置,是个坐标点 new_image.paste(image, (0, int((new_image_length - height) / 2))) else: new_image.paste(image, (int((new_image_length - width) / 2), 0)) return new_image def cut_image(image): width, height = image.size item_width =int(width /3) # 因为朋友圈一行放3张图 box_list = [] for i in range(0, 3): for j in range(0, 3): box = (j*item_width, i*item_width, (j+1)*item_width, (i+1)*item_width) # (left, top, right, bottom) box_list.append(box) image_list = [image.crop(box) for box in box_list] return image_list def save_images(image_list): index = 1 for image in image_list: image.save(str(index) + '.png', 'PNG') index += 1 if __name__ == '__main__': file_path = "t.jpg" # 把目标图片 input image 放到代码所处的文件夹里 image = Image.open(file_path) image = fill_image(image) image_list = cut_image(image) save_images(image_list)
