img = Image.open("/tmp/123/000000165.jpg") img_w, img_h = img.size # 宽度、高度最大值 > 2500等比例缩放 if max(img_h, img_w) > 2500: if img_h > img_w: img_w = int(2000 / img_h * img_w) img_h = 2000 else: img_h = int(2000 / img_w * img_h) img_w = 2000 img = img.resize((img_w, img_h), Image.ANTIALIAS) img.save("/tmp/12322222.jpg",'JPEG') stream = BytesIO() # 创建1个IO对象 img.save(stream, 'JPEG') # 把图片保存到内存 data = stream.getvalue() photo_base64 = base64.b64encode(data) print(photo_base64)
