font-list% : class?
superclass: object%

A font-list% object maintains a list of font% objects to avoid repeatedly creating fonts.

A global font list, the-font-list, is created automatically.

( new font-list% ) → ( is-a?/c font-list% )

Creates an empty font list.

size-in-pixels? : any/c = #f

Finds an existing font in the list or creates a new one (that is automatically added to the list). The arguments are the same as for creating a font% instance.
