从单个 jpg 到 web 转换到目录中的所有文件答案

【问题标题】：from single jpg to web conversion to all files in dir从单个 jpg 到 web 转换到目录中的所有文件
【发布时间】：2023-01-29 23:16:36
【问题描述】：

我制作了 python 代码将 jpg 转换为 webp

from PIL import Image
import PIL
import os
import glob



# Open The Image:
image_path = "D:/..../image_name.jpg"

image = Image.open(image_path)


# Convert the image to RGB Colour:
image = image.convert('RGB')

# Save The Image as webp:
new_image_path = "D:/.../converted_image_name.webp"

image.save(new_image_path, 'webp')

#open converted image for inspection

new_image = Image.open(new_image_path)
new_image.show()

不知道如何构建一个函数来对文件夹中的所有文件进行转换，同时保留原始文件名。

这是您的问题的有效解决方案：

from pathlib import Path

from PIL import Image
import PIL
import os
import glob

# the path to the directory containing the images
directory_path = 'D:PATH'

def convert_images(directory_path):
    for image_path in os.listdir(directory_path):
        if image_path.endswith(".jpg"):
            image = Image.open(os.path.join(directory_path, image_path))
            # get image filename without an extension
            name = Path(image_path).stem
            rgb_image = image.convert('RGB')
            new_image_path = f"{name}.webp"
            rgb_image.save(os.path.join(directory_path, new_image_path), 'webp')
            new_image = Image.open(new_image_path)
            new_image.show()
            continue
        else:
            continue


convert_images(directory_path)

我收到这个错误
你遇到了什么错误？
FileNotFoundError: [Errno 2] No such file or directory: 'resized_marie_jo-lingerie-underwired_bra-avero-0100410-%28maincolor%29-0_3515169.jpg' 所以它可以找到文件名，但不会打开它
这很奇怪。您是否将 directory_path = 'D:PATH' 变量设置为包含图像的目录（而不是实际图像路径）？另外，是否显示了错误行号？它可以帮助我了解哪里有问题。
错误行 ----> 7 image = Image.open(image_path)。 directory_path = 'D:/Lokale schijf/VANDERLINDEN/datafiles/BRANDS/VDV/images/SS2023/Python_API_imports/'

最终代码

from pathlib import Path

from PIL import Image
import PIL
import os
import glob

# the path to the directory containing the images
directory_path =  'D:/Lokale schijf/SS2023/Python_API_imports/'


def convert_images(directory_path):
    for image_path in os.listdir(directory_path):
        if image_path.endswith(".jpg"):
            image = Image.open(os.path.join(directory_path, image_path)) 
            # get image filename without an extension
            name = Path(image_path).stem
            rgb_image = image.convert('RGB')
            new_image_path = f"{name}.webp"
            rgb_image.save(os.path.join(directory_path, new_image_path), 'webp') 
            new_image = Image.open(new_image_path)
            new_image.show()
            continue
        

convert_images(directory_path)
