Fit to Height / Width

Thanks to ntjess for the code.

Fit to Height

If you need to make an image fill the remaining slide height, you can try the fit-to-height function:

#utils.fit-to-height(1fr)[BIG]

Function definition:

#let fit-to-height(
  width: none, prescale-width: none, grow: true, shrink: true, height, body
) = { .. }

Parameters:

• width: If specified, this will determine the width of the content after scaling. So, if you want the scaled content to fill half of the slide width, you can use width: 50%.
• prescale-width: This parameter allows you to make Typst's layout assume that the given content is to be laid out in a container of a certain width before scaling. For example, you can use prescale-width: 200% assuming the slide's width is twice the original.
• grow: Whether it can grow, default is true.
• shrink: Whether it can shrink, default is true.
• height: The specified height.
• body: The specific content.

Fit to Width

If you need to limit the title width to exactly fill the slide width, you can try the fit-to-width function:

#utils.fit-to-width(1fr)[#lorem(20)]

Function definition:

#let fit-to-width(grow: true, shrink: true, width, body) = { .. }

Parameters:

• grow: Whether it can grow, default is true.
• shrink: Whether it can shrink, default is true.
• width: The specified width.
• body: The specific content.
