# Module: `core.display`

Top-level display functions for displaying object in different formats.

Authors:

- Brian Granger

## 9 Classes

class `IPython.core.display.``DisplayObject`(data=None, url=None, filename=None)

  Bases: `object`

  An object that wraps data to be displayed.

  `__init__`(data=None, url=None, filename=None)

    Create a display object given raw data.

    When this object is returned by an expression or passed to the display function, it will result in the data being displayed in the frontend. The MIME type of the data should match the subclasses used, so the Png subclass should be used for ‘image/png’ data. If the data is a URL, the data will first be downloaded and then displayed. If

    Parameters:

    data : unicode, str or bytes

    > The raw data or a URL or file to load the data from

    url : unicode

    > A URL to download the data from.

    filename : unicode

    > Path to a local file to load the data from.

  `reload`()

    Reload the raw data from file or URL.

class `IPython.core.display.``Pretty`(data=None, url=None, filename=None)

  Bases: `IPython.core.display.DisplayObject`

class `IPython.core.display.``HTML`(data=None, url=None, filename=None)

  Bases: `IPython.core.display.DisplayObject`

class `IPython.core.display.``Math`(data=None, url=None, filename=None)

  Bases: `IPython.core.display.DisplayObject`

class `IPython.core.display.``Latex`(data=None, url=None, filename=None)

  Bases: `IPython.core.display.DisplayObject`

class `IPython.core.display.``SVG`(data=None, url=None, filename=None)

  Bases: `IPython.core.display.DisplayObject`

class `IPython.core.display.``JSON`(data=None, url=None, filename=None)

  Bases: `IPython.core.display.DisplayObject`

class `IPython.core.display.``Javascript`(data=None, url=None, filename=None, lib=None, css=None)

  Bases: `IPython.core.display.DisplayObject`

  `__init__`(data=None, url=None, filename=None, lib=None, css=None)

    Create a Javascript display object given raw data.

    When this object is returned by an expression or passed to the display function, it will result in the data being displayed in the frontend. If the data is a URL, the data will first be downloaded and then displayed.

    In the Notebook, the containing element will be available as element, and jQuery will be available. The output area starts hidden, so if the js appends content to element that should be visible, then it must call container.show() to unhide the area.

    Parameters:

    data : unicode, str or bytes

    > The Javascript source code or a URL to download it from.

    url : unicode

    > A URL to download the data from.

    filename : unicode

    > Path to a local file to load the data from.

    lib : list or str

    > A sequence of Javascript library URLs to load asynchronously before running the source code. The full URLs of the libraries should be given. A single Javascript library URL can also be given as a string.

    css: : list or str

    > A sequence of css files to load before running the source code. The full URLs of the css files should be given. A single css URL can also be given as a string.

class `IPython.core.display.``Image`(data=None, url=None, filename=None, format=u'png', embed=None, width=None, height=None, retina=False)

  Bases: `IPython.core.display.DisplayObject`

  `__init__`(data=None, url=None, filename=None, format=u'png', embed=None, width=None, height=None, retina=False)

    Create a display an PNG/JPEG image given raw data.

    When this object is returned by an expression or passed to the display function, it will result in the image being displayed in the frontend.

    Parameters:

    data : unicode, str or bytes

    > The raw image data or a URL or filename to load the data from. This always results in embedded image data.

    url : unicode

    > A URL to download the data from. If you specify url=, the image data will not be embedded unless you also specify embed=True.

    filename : unicode

    > Path to a local file to load the data from. Images from a file are always embedded.

    format : unicode

    > The format of the image data (png/jpeg/jpg). If a filename or URL is given for format will be inferred from the filename extension.

    embed : bool

    > Should the image data be embedded using a data URI (True) or be loaded using an <img> tag. Set this to True if you want the image to be viewable later with no internet connection in the notebook.

    > Default is True, unless the keyword argument url is set, then default value is False.

    > Note that QtConsole is not able to display images if embed is set to False

    width : int

    > Width to which to constrain the image in html

    height : int

    > Height to which to constrain the image in html

    retina : bool

    > Automatically set the width and height to half of the measured width and height. This only works for embedded images because it reads the width/height from image data. For non-embedded images, you can just set the desired display width and height directly.

    Examples

    # embedded image data, works in qtconsole and notebook # when passed positionally, the first arg can be any of raw image data, # a URL, or a filename from which to load image data. # The result is always embedding image data for inline images. Image(‘http://www.google.fr/images/srpr/logo3w.png‘) Image(‘/path/to/image.jpg’) Image(b’RAW_PNG_DATA...’)

    # Specifying Image(url=...) does not embed the image data, # it only generates <img> tag with a link to the source. # This will not work in the qtconsole or offline. Image(url=’http://www.google.fr/images/srpr/logo3w.png‘)

  `reload`()

    Reload the raw data from file or URL.

## 10 Functions

`IPython.core.display.``display`(*objs, **kwargs)

  Display a Python object in all frontends.

  By default all representations will be computed and sent to the frontends. Frontends can decide which representation is used and how.

  Parameters:

  objs : tuple of objects

  include : list or tuple, optional

  > A list of format type strings (MIME types) to include in the format data dict. If this is set only the format types included in this list will be computed.

  exclude : list or tuple, optional

  > A list of format type strings (MIME types) to exclude in the format data dict. If this is set all format types will be computed, except for those included in this argument.
