Question

我正在使用github中的script裁剪图像，只留下文本块。我试图将我的图像保存为tiff文件以获得最高质量，因为我将进行OCR。

现在我遇到的问题是它只适用于jpg - ＆gt; png，如果我在字符串末尾将值更改为tiff，我会收到类似

的错误

newOCR10.tiff image has wrong mode

关于如何解决这个问题的任何想法？

以下是我更改的代码：

if __name__ == '__main__':
    if len(sys.argv) == 2 and '*' in sys.argv[1]:
        files = glob.glob(sys.argv[1])
        random.shuffle(files)
    else:
        files = sys.argv[1:]

    for path in files:
        out_path = path.replace('.jpg', '.crop.png') //'.tiff' '.crop.tiff'
        if os.path.exists(out_path): continue
        try:
            process_image(path, out_path)
        except Exception as e:
            print '%s %s' % (path, e)

tiffinfo newOCR6.tiff返回此信息：
