How to convert an entire folder of BMP images to PPM in Python?

Question

from PIL import Image 
import glob, os
directory = "your path "
for infile in glob.glob("*.bmp"):
    file, ext = os.path.splitext(infile)
    im = Image.open(infile)
    im.save(file + ".ppm", "PPM")

I was able to convert only one image, can you please help to get entire image converted to ppm format

只要我在感兴趣的目录中，您的代码就可以为我工作。您的代码未使用directory信息，因此，如果您在其他目录中，则可能找不到带有.ppm的任何glob文件，因此是空操作。我将修改您的代码，如下所示：

from PIL import Image 
import glob, os
target_directory = "/path/to/folder"
for infile in glob.glob(os.path.join(target_directory, "*.bmp")):
    file, ext = os.path.splitext(infile)
    im = Image.open(infile)
    im.save(file + ".ppm", "PPM")
