import panel as pn
pn.extension()
The PNG pane embeds a .png image file in a panel if provided a local path, or will link to a remote image if provided a URL.
Parameters:#
For details on other options for customizing the component see the layout and styling how-to guides.
alt_text(str, default=None): alt text to add to the image tag. The alt text is shown when a user cannot load or display the image.embed(boolean, default=False): If given a URL to an image this determines whether the image will be embedded as base64 or merely linked to.fixed_aspect(boolean, default=True): Whether the aspect ratio of the image should be forced to be equal.link_url(str, default=None): A link URL to make the image clickable and link to some other website.object(str or object): The PNG file to display. Can be a string pointing to a local or remote file, or an object with a_repr_png_method.styles(dict): Dictionary specifying CSS stylestarget(str, default=”_blank”): Where to open the document linked in the link_url.
The PNG pane can be pointed at any local or remote .png file. If given a URL starting with http or https, the embed parameter determines whether the image will be embedded or linked to:
png_pane = pn.pane.PNG('https://assets.holoviz.org/panel/samples/png_sample.png')
png_pane
We can scale the size of the image by setting a specific fixed width or height:
png_pane.clone(width=400)
Alternatively we can scale the width and height using the sizing_mode:
pn.pane.PNG(
'https://assets.holoviz.org/panel/samples/png_sample2.png', sizing_mode='scale_width'
)
Note that by default the aspect ratio of the image is fixed, and so there may be a gap beside or below the image even in responsive sizing modes. To override this behavior set fixed_aspect=False or provide fixed width and height values.
