如何使用EXIF的信息制作django

如何使用EXIF的信息制作django-photologue自动旋转图像？(How to make django-photologue autorotate image with info from EXIF?)

我需要在上传时根据EXIF中的信息更改图像的方向。 这有什么“标准”方式吗？ 我现在试图修补模型，但不确定它的正确方法。

I need to change orientation of image according to info in EXIF on upload. Is there any "standard" way for this? Im trying to patch models now, but not sure its right way.

好吧，我做了这个文件photologue / models.py：

IMAGE_EXIF_ORIENTATION_MAP = { 6: 0, 3: 2, 8: 3, 1: 4, } def pre_cache(self): if self.EXIF.get('Orientation', 1) is not None: im = Image.open(self.image.path) im = im.transpose(IMAGE_EXIF_ORIENTATION_MAP[self.EXIF.get('Orientation', 1)]) im.save(self.image.path) cache = PhotoSizeCache() for photosize in cache.sizes.values(): if photosize.pre_cache: self.create_size(photosize)

Well, I did it like this file photologue/models.py:

IMAGE_EXIF_ORIENTATION_MAP = { 6: 0, 3: 2, 8: 3, 1: 4, } def pre_cache(self): if self.EXIF.get('Orientation', 1) is not None: im = Image.open(self.image.path) im = im.transpose(IMAGE_EXIF_ORIENTATION_MAP[self.EXIF.get('Orientation', 1)]) im.save(self.image.path) cache = PhotoSizeCache() for photosize in cache.sizes.values(): if photosize.pre_cache: self.create_size(photosize)
