`TiffTags` Module¶

The TiffTags module exposes many of the stantard TIFF metadata tag numbers, names, and type information.

PIL.TiffTags.lookup(tag)[源代码]¶

参数:	tag – Integer tag number
返回:	Taginfo namedtuple, From the `TAGS_V2` info if possible, otherwise just populating the value and name from `TAGS`. If the tag is not recognized, “unknown” is returned for the name

class PIL.TiffTags.TagInfo[源代码]¶

__init__(self, value=None, name="unknown", type=None, length=0, enum=None)¶

参数:	value – Integer Tag Number name – Tag Name type – Integer type from `PIL.TiffTags.TYPES` length – Array length: 0 == variable, 1 == single value, n = fixed enum – Dict of name:integer value options for an enumeration

cvt_enum(self, value)[源代码]¶

参数:	value – The enumerated value name
返回:	The integer corresponding to the name.

PIL.TiffTags.TAGS_V2¶: The TAGS_V2 dictionary maps 16-bit integer tag numbers to PIL.TagTypes.TagInfo tuples for metadata fields defined in the TIFF spec.

PIL.TiffTags.TAGS¶

The TAGS dictionary maps 16-bit integer TIFF tag number to descriptive string names. For instance:

>>> from PIL.TiffTags import TAGS
>>> TAGS[0x010e]
'ImageDescription'

This dictionary contains a superset of the tags in TAGS_V2, common EXIF tags, and other well known metadata tags.

PIL.TiffTags.TYPES¶: The TYPES dictionary maps the TIFF type short integer to a human readable type name.
