In normal cases, you don't need to call this method, since the Image class automatically loads an opened image when it is accessed for the first time. If the file associated with the image was opened by Pillow, then this method will close it. The exception to this is if the image has multiple frames, in which case the file will be left open for seek operations.

For the "P" mode, this method translates pixels through the palette. If mode is omitted, a mode is chosen so that all information in the image and the palette can be represented without a palette. The current version supports all possible conversions between "L", "RGB" and "CMYK." The **matrix** argument only supports "L" and "RGB". When translating a color image to greyscale (mode "L"), the library uses the ITU-R 601-2 luma transform:: L = R * 299/1000 + G * 587/1000 + B * 114/1000 The default method of converting a greyscale ("L") or "RGB" image into a bilevel (mode "1") image uses Floyd-Steinberg dither to approximate the original image luminosity levels. If dither is NONE, all values larger than 128 are set to 255 (white), all other values to 0 (black). To use other thresholds, use the :py:meth:`~PIL.Image.Image.point` method. When converting from "RGBA" to "P" without a **matrix** argument, this passes the operation to :py:meth:`~PIL.Image.Image.quantize`, and **dither** and **palette** are ignored. :param mode: The requested mode. See: :ref:`concept-modes`. :param matrix: An optional conversion matrix. If given, this should be 4- or 12-tuple containing floating point values. :param dither: Dithering method, used when converting from mode "RGB" to "P" or from "RGB" or "L" to "1". Available methods are NONE or FLOYDSTEINBERG (default). Note that this is not used when **matrix** is supplied. :param palette: Palette to use when converting from mode "RGB" to "P". Available palettes are WEB or ADAPTIVE. :param colors: Number of colors to use for the ADAPTIVE palette.

The histogram is returned as a list of pixel counts, one for each pixel value in the source image. If the image has more than one band, the histograms for all bands are concatenated (for example, the histogram for an "RGB" image contains 768 values). A bilevel image (mode "1") is treated as a greyscale ("L") image by this method. If a mask is provided, the method returns a histogram for those parts of the image where the mask image is non-zero. The mask image must have the same size as the image, and be either a bi-level image (mode "1") or a greyscale image ("L"). :param mask: An optional mask. :param extrema: An optional tuple of manually-specified extrema. :returns: A list containing pixel counts. r� �r' r( N)r� r r0 rV r5 �r� �maskr6 r r r r0 1 s zImage.histogramc C sT | � � |r$|� � | j�d|j�S | jdkrJ|dkr>| �� }| j�|�S | j�� S )ah Calculates and returns the entropy for the image.

The box argument is either a 2-tuple giving the upper left corner, a 4-tuple defining the left, upper, right, and lower pixel coordinate, or None (same as (0, 0)). See :ref:`coordinate-system`. If a 4-tuple is given, the size of the pasted image must match the size of the region. If the modes don't match, the pasted image is converted to the mode of this image (see the :py:meth:`~PIL.Image.Image.convert` method for details). Instead of an image, the source can be a integer or tuple containing pixel values. The method then fills the region with the given color. When creating RGB images, you can also use color strings as supported by the ImageColor module. If a mask is given, this method updates only the regions indicated by the mask. You can use either "1", "L" or "RGBA" images (in the latter case, the alpha band is used as mask). Where the mask is 255, the given image is copied as is. Where the mask is 0, the current value is preserved. Intermediate values will mix the two images together, including their alpha channels if they have them. See :py:meth:`~PIL.Image.Image.alpha_composite` if you want to combine images with respect to their alpha channels. :param im: Source image or pixel value (integer or tuple). :param box: An optional 4-tuple giving the region to paste into. If a 2-tuple is used instead, it's treated as the upper left corner. If omitted or None, the source is pasted into the upper left corner. If an image is given as the second argument and there is no third, the box defaults to (0, 0), and the second argument is interpreted as a mask image. :param mask: An optional mask image.

This method modifies the image to contain a thumbnail version of itself, no larger than the given size. This method calculates an appropriate thumbnail size to preserve the aspect of the image, calls the :py:meth:`~PIL.Image.Image.draft` method to configure the file reader (where applicable), and finally resizes the image. Note that this function modifies the :py:class:`~PIL.Image.Image` object in place. If you need to use the full resolution image as well, apply this method to a :py:meth:`~PIL.Image.Image.copy` of the original image. :param size: Requested size. :param resample: Optional resampling filter. This can be one of :py:attr:`PIL.Image.NEAREST`, :py:attr:`PIL.Image.BILINEAR`, :py:attr:`PIL.Image.BICUBIC`, or :py:attr:`PIL.Image.LANCZOS`. If omitted, it defaults to :py:attr:`PIL.Image.BICUBIC`.

First, reducing the image by integer times using :py:meth:`~PIL.Image.Image.reduce` or :py:meth:`~PIL.Image.Image.draft` for JPEG images. Second, resizing using regular resampling. The last step changes size no less than by ``reducing_gap`` times. ``reducing_gap`` may be None (no first step is performed) or should be greater than 1.0. The bigger ``reducing_gap``, the closer the result to the fair resampling. The smaller ``reducing_gap``, the faster resizing. With ``reducing_gap`` greater or equal to 3.0, the result is indistinguishable from fair resampling in most cases. The default value is 2.0 (very close to fair resampling while still being faster in many cases). :returns: None r r N)r ry ) rW r� r r& rw r r� rV r� r� ) r� rW r` ry r= r> r �resr r r r � thumbnail� s, & zImage.thumbnailc C s | j dkr*| �d��||||||��d�S | j dkrT| �d��||||||��d�S t|t�rp|j|| ||d�S t|d�r�|�� \}}|dkr�td��t| j ||�}| j � � |_ |t kr�|D ] \}} |� || t | ||dk� q�n |� d | | ||||dk� |S ) a^ Transforms this image.

See: :ref:`concept-modes`. :param size: A 2-tuple, containing (width, height) in pixels. :param color: What color to use for the image. Default is black. If given, this should be a single integer or floating point value for single-band modes, and a tuple for multi-band modes (one value per band). When creating RGB images, you can also use color strings as supported by the ImageColor module. If the color is None, the image is not initialised. :returns: An :py:class:`~PIL.Image.Image` object.

In its simplest form, this function takes three arguments (mode, size, and unpacked pixel data). You can also use any pixel decoder supported by PIL. For more information on available decoders, see the section :ref:`Writing Your Own File Decoder <file-decoders>`. Note that this function decodes pixel data only, not entire images. If you have an entire image in a string, wrap it in a :py:class:`~io.BytesIO` object, and use :py:func:`~PIL.Image.open` to load it. :param mode: The image mode. See: :ref:`concept-modes`. :param size: The image size. :param data: A byte buffer containing raw data for the given mode. :param decoder_name: What decoder to use. :param args: Additional parameters for the given decoder. :returns: An :py:class:`~PIL.Image.Image` object. r r r� r )r� ra rv rw r� r� �rV rW r� r~ r r r r r r� � s r� c O s t d��d S r� r� )r r� r r r r� s �r� c G s� t |� t|�dkr*t|d t�r*|d }|dkr~|dkrD| ddf}|d tkr~t| d�}|�t�|||dd|��}d|_ |S t | ||||�S )a� Creates an image memory referencing pixel data in a byte buffer. This function is similar to :py:func:`~PIL.Image.frombytes`, but uses data in the byte buffer, where possible. This means that changes to the original buffer object are reflected in this image). Not all modes can share memory; supported modes include "L", "RGBX", "RGBA", and "CMYK". Note that this function decodes pixel data only, not entire images. If you have an entire image file in a string, wrap it in a **BytesIO** object, and use :py:func:`~PIL.Image.open` to load it. In the current version, the default parameters used for the "raw" decoder differs from that used for :py:func:`~PIL.Image.frombytes`. This is a bug, and will probably be fixed in a future release. The current release issues a warning if you do this; to disable the warning, you should provide the full set of parameters. See below for details. :param mode: The image mode. See: :ref:`concept-modes`. :param size: The image size. :param data: A bytes or other buffer object containing raw data for the given mode. :param decoder_name: What decoder to use. :param args: Additional parameters for the given decoder. For the default encoder ("raw"), it's recommended that you provide the full set of parameters:: frombuffer(mode, size, data, "raw", mode, 0, 1) :returns: An :py:class:`~PIL.Image.Image` object. .. versionadded:: 1.1.4 r r r� r r N) r� ra rv rw � _MAPMODESr� r� r{ Z map_bufferr� r� r� r r r � frombuffer s # r� c C s | j }|d }t|�}|�dd�}|dkr�z d|dd� |d f}W n tk rb td��Y nX zt| \}}W q� tk r� td| ��Y q�X n|}|d kr�d}n|d kr�d }nd }||kr�td ||f ��|d |d f} |dk �r t| d��r| �� } n| � � } t || | d|dd�S )a� Creates an image memory from an object exporting the array interface (using the buffer protocol).
