class PIL.IcoImagePlugin.IcoImageFile(fp=None, filename=None)

Bases: ImageFile

PIL read-only image support for Microsoft Windows .ico files.

Handles classic, XP and Vista icon formats.

When saving, PNG compression is used. Support for this was only added in Windows Vista. If you are unable to view the icon in Windows, convert the image to “RGBA” mode before saving.

  • Key: numerical TIFF tag number

  • Value: integer corresponding to the data type from TiffTags.TYPES

  New in version 3.0.0.

  • Value: decoded data, as tuple for multiple values

• self._tagdata = {}

  • Key: numerical TIFF tag number

  • Value: undecoded byte string from file

• self._tags_v1 = {}

  • Key: numerical TIFF tag number

  • Value: decoded data in the v1 format

Tags will be found in the private attributes self._tagdata, and in self._tags_v2 once decoded.

self.legacy_api is a value for internal use, and shouldn’t be changed from outside code. In cooperation with ImageFileDirectory_v1, if legacy_api is true, then decoded tags will be populated into both _tags_v1 and _tags_v2. _tags_v2 will be used if this IFD is used in the TIFF save routine. Tags should be read from _tags_v1 if legacy_api == true.

get_child_images()

get_photoshop_blocks()

Returns a dictionary of Photoshop “Image Resource Blocks”. The keys are the image resource ID. For more information, see https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/#50577409_pgfId-1037727

Returns:

Photoshop “Image Resource Blocks” in a dictionary.

getxmp()

Returns a dictionary containing the XMP tags. Requires defusedxml to be installed.

Returns:

XMP tags in a dictionary.

load()

Load image data based on tile list

property n_frames

seek(frame)

Select a given frame as current image

Image file directory (tag dictionary)

tell()

Return the current frame number

WebPImagePlugin Module

class PIL.WebPImagePlugin.WebPImageFile(fp=None, filename=None)

Bases: ImageFile

format = 'WEBP'

format_description = 'WebP image'

load()

Load image data based on tile list

seek(frame)

Seeks to the given frame in this sequence file. If you seek beyond the end of the sequence, the method raises an EOFError exception. When a sequence file is opened, the library automatically seeks to frame 0.

See tell().

If defined, n_frames refers to the number of available frames.

Parameters:

frame – Frame number, starting at 0.

Raises:

EOFError – If the call attempts to seek beyond the end of the sequence.

tell()

Returns the current frame number. See seek().

If defined, n_frames refers to the number of available frames.

Returns:

Frame number, starting with 0.

WmfImagePlugin Module

class PIL.WmfImagePlugin.WmfStubImageFile(fp=None, filename=None)

Bases: StubImageFile

load(dpi=None)

Load image data based on tile list

PIL.WmfImagePlugin.register_handler(handler)

Install application-specific WMF image handler.

Parameters:

handler – Handler object.
