PIL.TiffImagePlugin.ImageFileDirectory_v2(ifh=b'II*x00x00x00x00x00', prefix=None)[源代码]¶ 基类:
collections.abc.MutableMappingThis class represents a TIFF tag directory. To speed things up, we don’t decode tags unless they’re asked for.
Exposes a dictionary interface of the tags in the directory:
ifd = ImageFileDirectory_v2() ifd[key] = 'Some Data' ifd.tagtype[key] = 2 print(ifd[key]) 'Some Data'
Individual values are returned as the strings or numbers, sequences are returned as tuples of the values.
The tiff metadata type of each item is stored in a dictionary of tag types in ~PIL.TiffImagePlugin.ImageFileDirectory_v2.tagtype. The types are read from a tiff file, guessed from the type added, or added manually.
Data Structures:
- self.tagtype = {}
- Key: numerical tiff tag number
- Value: integer corresponding to the data type from
- ~PIL.TiffTags.TYPES`
