IcoImageFile
(fp=None, filename=None)[源代码]¶ 基类:
PIL.ImageFile.ImageFile
PIL read-only image support for Microsoft Windows .ico files.
By default the largest resolution image in the file will be loaded. This can be changed by altering the ‘size’ attribute before calling ‘load’.
The info dictionary has a key ‘sizes’ that is a list of the sizes available in the icon file.
Handles classic, XP and Vista icon formats.
When saving, PNG compression is used. Support for this was only added in Windows Vista.
This plugin is a refactored version of Win32IconImagePlugin by Bryan Davis <casadebender@gmail.com>. https://code.google.com/archive/p/casadebender/wikis/Win32IconImagePlugin.wiki

draft
(mode, size)[源代码]¶ Configures the image file loader so it returns a version of the image that as closely as possible matches the given mode and size. For example, you can use this method to convert a color JPEG to greyscale while loading it.
If any changes are made, returns a tuple with the chosen
mode
andbox
with coordinates of the original image within the altered one.Note that this method modifies the
Image
object in place. If the image has already been loaded, this method has no effect.Note: This method is not implemented for most images. It is currently implemented only for JPEG and MPO images.

This class represents the legacy interface to a TIFF tag directory.
Exposes a dictionary interface of the tags in the directory:
ifd = ImageFileDirectory_v1() ifd[key] = 'Some Data' ifd.tagtype[key] = TiffTags.ASCII print(ifd[key]) ('Some Data',)
Also contains a dictionary of tag types as read from the tiff image file, ~PIL.TiffImagePlugin.ImageFileDirectory_v1.tagtype.
Values are returned as a tuple.

ImageFileDirectory_v2
(ifh=b'II*x00x00x00x00x00', prefix=None)[源代码]¶ 基类:
collections.abc.MutableMapping
This 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] = TiffTags.ASCII 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`
