    Reading sequences
    ~~~~~~~~~~~~~~~~~

    The GIF loader supports the :py:meth:`~file.seek` and :py:meth:`~file.tell`

    the file by seeking to the first frame. Random access is not supported.

    ``im.seek()`` raises an ``EOFError`` if you try to seek after the last frame.

    Saving
    ~~~~~~

    When calling :py:meth:`~PIL.Image.Image.save`, the following options
    are available::

        im.save(out, save_all=True, append_images=[im1, im2, ...])

    **save_all**
        If present and true, all frames of the image will be saved. If
        not, then only the first frame of a multiframe image will be saved.

    **append_images**
        A list of images to append as additional frames. Each of the
        images in the list can be single or multiframe images.
        This is currently only supported for GIF, PDF, TIFF, and WebP.

    **duration**
        The display duration of each frame of the multiframe gif, in
        milliseconds. Pass a single integer for a constant duration, or a
        list or tuple to set the duration for each frame separately.

    **loop**
        Integer number of times the GIF should loop.

    **optimize**
        If present and true, attempt to compress the palette by
        eliminating unused colors. This is only useful if the palette can
        be compressed to the next smaller power of 2 elements.

    **palette**
        Use the specified palette for the saved image. The palette should
        be a bytes or bytearray object containing the palette entries in
        RGBRGB... form. It should be no more than 768 bytes. Alternately,
        the palette can be passed in as an
        :py:class:`PIL.ImagePalette.ImagePalette` object.

    **disposal**
        Indicates the way in which the graphic is to be treated after being displayed.

        * 0 - No disposal specified.
        * 1 - Do not dispose.
        * 2 - Restore to background color.
        * 3 - Restore to previous content.

         Pass a single integer for a constant disposal, or a list or tuple
         to set the disposal for each frame separately.

    Reading local images
    ~~~~~~~~~~~~~~~~~~~~

    The GIF loader creates an image memory the same size as the GIF file’s *logical
    screen size*, and pastes the actual pixel data (the *local image*) into this
    image. If you only want the actual pixel rectangle, you can manipulate the
    :py:attr:`~PIL.Image.Image.size` and :py:attr:`~PIL.Image.Image.tile`
    attributes before loading the file::

        im = Image.open(...)

    .. versionadded:: Pillow  2.4.0

    PIL reads and writes JPEG 2000 files containing ``L``, ``LA``, ``RGB`` or
    ``RGBA`` data.  It can also read files containing ``YCbCr`` data, which it
    converts on read into ``RGB`` or ``RGBA`` depending on whether or not there is
    an alpha channel.  PIL supports JPEG 2000 raw codestreams (``.j2k`` files), as
    well as boxed JPEG 2000 files (``.j2p`` or ``.jpx`` files).  PIL does *not*
    support files whose components have different sampling frequencies.

    When loading, if you set the ``mode`` on the image prior to the
    :py:meth:`~PIL.Image.Image.load` method being invoked, you can ask PIL to
    convert the image to either ``RGB`` or ``RGBA`` rather than choosing for
    itself.  It is also possible to set ``reduce`` to the number of resolutions to
    discard (each one reduces the size of the resulting image by a factor of 2),
    and ``layers`` to specify the number of quality layers to load.

    The :py:meth:`~PIL.Image.Image.save` method supports the following options:

    **offset**
        The image offset, as a tuple of integers, e.g. (16, 16)

    **tile_offset**
        The tile offset, again as a 2-tuple of integers.

    **tile_size**
        The tile size as a 2-tuple.  If not specified, or if set to None, the
        image will be saved without tiling.

    **quality_mode**
        Either `"rates"` or `"dB"` depending on the units you want to use to
        specify image quality.

    **quality_layers**
        A sequence of numbers, each of which represents either an approximate size
        reduction (if quality mode is `"rates"`) or a signal to noise ratio value
        in decibels.  If not specified, defaults to a single layer of full quality.

    **num_resolutions**
        The number of different image resolutions to be stored (which corresponds
        to the number of Discrete Wavelet Transform decompositions plus one).

    **codeblock_size**
        The code-block size as a 2-tuple.  Minimum size is 4 x 4, maximum is 1024 x
        1024, with the additional restriction that no code-block may have more
        than 4096 coefficients (i.e. the product of the two numbers must be no
        greater than 4096).

    **precinct_size**
        The precinct size as a 2-tuple.  Must be a power of two along both axes,
        and must be greater than the code-block size.

    **irreversible**
        If ``True``, use the lossy Irreversible Color Transformation
        followed by DWT 9-7.  Defaults to ``False``, which means to use the
        Reversible Color Transformation with DWT 5-3.

    **progression**
        Controls the progression order; must be one of ``"LRCP"``, ``"RLCP"``,
        ``"RPCL"``, ``"PCRL"``, ``"CPRL"``.  The letters stand for Component,
        Position, Resolution and Layer respectively and control the order of
        encoding, the idea being that e.g. an image encoded using LRCP mode can
        have its quality layers decoded as they arrive at the decoder, while one
        encoded using RLCP mode will have increasing resolutions decoded as they
        arrive, and so on.

    **cinema_mode**
        Set the encoder to produce output compliant with the digital cinema
        specifications.  The options here are ``"no"`` (the default),
        ``"cinema2k-24"`` for 24fps 2K, ``"cinema2k-48"`` for 48fps 2K, and
        ``"cinema4k-24"`` for 24fps 4K.  Note that for compliant 2K files,
        *at least one* of your image dimensions must match 2048 x 1080, while
        for compliant 4K files, *at least one* of the dimensions must match
        4096 x 2160.

    .. note::

       To enable JPEG 2000 support, you need to build and install the OpenJPEG
       library, version 2.0.0 or higher, before building the Python Imaging
       Library.

       Windows users can install the OpenJPEG binaries available on the
       OpenJPEG website, but must add them to their PATH in order to use PIL (if
       you fail to do this, you will get errors about not being able to load the
       ``_imaging`` DLL).

        or a byte string with alpha values for each palette entry.

        For ``L`` and ``RGB`` images, the color that represents full transparent
        pixels in this image.

        This key is omitted if the image is not a transparent palette image.

    ``Open`` also sets ``Image.text`` to a list of the values of the

    compressed chunks are limited to a decompressed size of
    ``PngImagePlugin.MAX_TEXT_CHUNK``, by default 1MB, to prevent
    decompression bombs. Additionally, the total size of all of the text
    chunks is limited to ``PngImagePlugin.MAX_TEXT_MEMORY``, defaulting to
    64MB.

    The :py:meth:`~PIL.Image.Image.save` method supports the following options:

    **optimize**
        If present and true, instructs the PNG writer to make the output file as
        small as possible. This includes extra processing in order to find optimal
        encoder settings.

    **transparency**
        For ``P``, ``L``, and ``RGB`` images, this option controls what
        color image to mark as transparent.

        For ``P`` images, this can be a either the palette index,
        or a byte string with alpha values for each palette entry.

    **dpi**
        A tuple of two numbers corresponding to the desired dpi in each direction.

    **pnginfo**
        A :py:class:`PIL.PngImagePlugin.PngInfo` instance containing text tags.

    **compress_level**
        ZLIB compression level, a number between 0 and 9: 1 gives best speed,
        9 gives best compression, 0 gives no compression at all. Default is 6.
        When ``optimize`` option is True ``compress_level`` has no effect
        (it is set to 9 regardless of a value passed).

    **icc_profile**
        The ICC Profile to include in the saved file.

    **bits (experimental)**
        For ``P`` images, this option controls how many bits to store. If omitted,
        the PNG writer uses 8 bits (256 colors).

    **dictionary (experimental)**
        Set the ZLIB encoder dictionary.

    .. note::

        To enable PNG support, you need to build and install the ZLIB compression

    Pillow reads and writes TIFF files. It can read both striped and tiled

    of compressed TIFF files. If not, PIL will only read and write
    uncompressed files.

    .. note::

        Beginning in version 5.0.0, Pillow requires libtiff to read or
        write compressed files. Prior to that release, Pillow had buggy
        support for reading Packbits, LZW and JPEG compressed TIFFs
        without using libtiff.

    The :py:meth:`~PIL.Image.Image.write` method sets the following
    :py:attr:`~PIL.Image.Image.info` properties:

    **compression**
        Compression mode.

        .. versionadded:: Pillow  2.0.0

    **dpi**
        Image resolution as an ``(xdpi, ydpi)`` tuple, where applicable. You can use
        the :py:attr:`~PIL.Image.Image.tag` attribute to get more detailed
        information about the image resolution.

    **resolution**
        Image resolution as an ``(xres, yres)`` tuple, where applicable. This is a
        measurement in whichever unit is specified by the file.

        .. versionadded:: Pillow  1.1.5


    The :py:attr:`~PIL.Image.Image.tag_v2` attribute contains a dictionary
    of TIFF metadata. The keys are numerical indexes from
    :py:attr:`~PIL.TiffTags.TAGS_V2`.  Values are strings or numbers for single
    items, multiple values are returned in a tuple of values. Rational
    numbers are returned as a :py:class:`~PIL.TiffImagePlugin.IFDRational`
    object.

        .. versionadded:: Pillow  3.0.0

    For compatibility with legacy code, the
    :py:attr:`~PIL.Image.Image.tag` attribute contains a dictionary of
    decoded TIFF fields as returned prior to version 3.0.0.  Values are
    returned as either strings or tuples of numeric values. Rational

    Saving Tiff Images
    ~~~~~~~~~~~~~~~~~~

    The :py:meth:`~PIL.Image.Image.save` method can take the following keyword arguments:

    **save_all**
        If true, Pillow will save all frames of the image to a multiframe tiff document.

        .. versionadded:: Pillow  3.4.0

    **tiffinfo**
        A :py:class:`~PIL.TiffImagePlugin.ImageFileDirectory_v2` object or dict
        object containing tiff tags and values. The TIFF field type is
        autodetected for Numeric and string values, any other types
        require using an :py:class:`~PIL.TiffImagePlugin.ImageFileDirectory_v2`
        object and setting the type in
        :py:attr:`~PIL.TiffImagePlugin.ImageFileDirectory_v2.tagtype` with
        the appropriate numerical value from
        ``TiffTags.TYPES``.

        .. versionadded:: Pillow  2.3.0

        Metadata values that are of the rational type should be passed in
        using a :py:class:`~PIL.TiffImagePlugin.IFDRational` object.

        .. versionadded:: Pillow  3.1.0

        For compatibility with legacy code, a
        :py:class:`~PIL.TiffImagePlugin.ImageFileDirectory_v1` object may
        be passed in this field. However, this is deprecated.

        .. versionadded:: Pillow  3.0.0

     .. note::

        Only some tags are currently supported when writing using
        libtiff. The supported list is found in
        :py:attr:`~PIL:TiffTags.LIBTIFF_CORE`.

    **compression**
        A string containing the desired compression method for the
        file. (valid only with libtiff installed) Valid compression
        methods are: ``None``, ``"tiff_ccitt"``, ``"group3"``,
        ``"group4"``, ``"tiff_jpeg"``, ``"tiff_adobe_deflate"``,
        ``"tiff_thunderscan"``, ``"tiff_deflate"``, ``"tiff_sgilog"``,
        ``"tiff_sgilog24"``, ``"tiff_raw_16"``

    These arguments to set the tiff header fields are an alternative to
    using the general tags available through tiffinfo.
