plotly.io.write_image

plotly.io.write_image(fig, file, format=None, scale=None, width=None, height=None, validate=True, engine='auto')

Convert a figure to a static image and write it to a file or writeable object

Parameters

  • fig – Figure object or dict representing a figure

  • file (str or writeable) – A string representing a local file path or a writeable object (e.g. a pathlib.Path object or an open file descriptor)

  • format (str or None) –

    The desired image format. One of

    • ’png’

    • ’jpg’ or ‘jpeg’

    • ’webp’

    • ’svg’

    • ’pdf’

    • ’eps’ (Requires the poppler library to be installed and on the PATH)

    If not specified and file is a string then this will default to the file extension. If not specified and file is not a string then this will default to:

    • plotly.io.kaleido.scope.default_format if engine is “kaleido”

    • plotly.io.orca.config.default_format if engine is “orca”

  • width (int or None) –

    The width of the exported image in layout pixels. If the scale property is 1.0, this will also be the width of the exported image in physical pixels.

    If not specified, will default to:

    • plotly.io.kaleido.scope.default_width if engine is “kaleido”

    • plotly.io.orca.config.default_width if engine is “orca”

  • height (int or None) –

    The height of the exported image in layout pixels. If the scale property is 1.0, this will also be the height of the exported image in physical pixels.

    If not specified, will default to:

    • plotly.io.kaleido.scope.default_height if engine is “kaleido”

    • plotly.io.orca.config.default_height if engine is “orca”

  • scale (int or float or None) –

    The scale factor to use when exporting the figure. A scale factor larger than 1.0 will increase the image resolution with respect to the figure’s layout pixel dimensions. Whereas as scale factor of less than 1.0 will decrease the image resolution.

    If not specified, will default to:

    • plotly.io.kaleido.scope.default_scale if engine is “kaleido”

    • plotly.io.orca.config.default_scale if engine is “orca”

  • validate (bool) – True if the figure should be validated before being converted to an image, False otherwise.

  • engine (str) –

    Image export engine to use:

    • ”kaleido”: Use Kaleido for image export

    • ”orca”: Use Orca for image export

    • ”auto” (default): Use Kaleido if installed, otherwise use orca

Returns
