Output an image for a link using UI thumbnails.



A links element to link from.


A list of candidate uix:thumb elements.


A link role, used to select the appropriate thumbnail.


The width to fit thumbnails into.


The height to fit thumbnails into.

This template selects the best-fit thumbnail from thumbs, based on how well the aspect ratio and dimensions of each image matches the width and height parameters. It outputs an HTML img element for the best-fit thumbnail. It calls mal2thml.ui.links.img.src to output the src attribute, and calls mal2html.ui.links.img.attrs to output width and height attributes.

Before checking for a best-fit thumbnail on dimensions, this template first looks for uix:thumb elements with the type attribute set to "links". Within those, it looks for uix:thumb elements whose role attribute matches the role parameter. This is similar to how link titles are selected.

If the thumbs parameter is empty, this template attempts to use a default thumbnail provided by a uix:thumb child element of node.

The width and height parameters can be computed automatically from the node element.
