向图像添加透明填充

Question

如何为特定目录中的所有图像添加透明填充？

例如，我有分辨率为 100x100px 的图像并想添加：顶部 20px， 10px 对，底部 40px，还剩 20 像素。

Answer 1

这段代码对我有用：

for imagePath in os.listdir(inPath):

    # imagePath contains name of the image
    inputPath = os.path.join(inPath, imagePath)

    # inputPath contains the full directory name
    img = Image.open(inputPath)

    # fullOutPath contains the path of the output
    fullOutPath = os.path.join(outPath, imagePath)

    # add padding
    img = ImageOps.expand(img, border=(10,10,10,10), fill=(0,0,0,0) )

    # image that needs to be generated
    img.save(fullOutPath)

    print(fullOutPath)
