ImageBasea_ Encodes an image as base64 and wraps it in a Bokeh Div model. This is an abstract base class that needs the image type to be specified and specific code for determining the image shape. The filetype determines the filetype, extension, and MIME type for this image. Each image type (png,jpg,gif) has a base class that supports anything with a `_repr_X_` method (where X is `png`, `gif`, etc.), a local file with the given file extension, or a HTTP(S) url with the given extension. Subclasses of each type can provide their own way of obtaining or generating a PNG. Nzv alt text to add to the image tag. The alt text is shown when a user cannot load or display the image.rz( Optional caption for the image.TzT Whether the aspect ratio of the image should be forced to be equal.zW A link URL to make the image clickable and link to some other website.)alt_textcaptionlink_urlrrrr r!r"r#)rv fixed_aspectrxrwrrrz!''_target_transformscCstdS)z'Calculate and return image width,heightN)NotImplementedError)rKrNr,r,r-rIszImageBase._imgshaper%z str | None)srcr r!c Cs|jrd|jnd}|r&d|dnd}|r:d|dnd}|jrHdnd}d|d |d |d||d }|jrd |jd |d}|jrd|d|jd}t|S)Nzalt= width: ; height: containfill z zz
