3 Fullscreen vs. Widescreen Aspect Ratio

Fullscreen (4:3) versus widescreen (16:9) aspect mode is a property of an individual slide that can be selected using the #:aspect argument to slide. The slideshow/widescreen language provides a variant of slide that makes 'widescreen the default value of #:aspect, while slideshow/fullscreen provides a variant of slide that makes 'fullscreen the default.

When a slide’s aspect is not specified, then it adopts an aspect that can be selected via the --widescreen or --fullscreen flag when Slideshow starts. (That selection can be made “sticky” as the default for future runs by using the --save-aspect flag.) Selecting an aspect also affects the values of client-w, client-h, full-page, and titleless-page from slideshow, but it does not affect the bindings from slideshow/widescreen or slideshow/fullscreen. Keep in mind that specifying #:aspect for slide does not affect the value of client-w, etc., for constructing the slide’s content, but you can use get-client-w, etc., to obtain the aspect-specific metrics.

Use the slideshow language for slides and libraries that are meant to adapt to a user’s selected aspect, and use slideshow/fullscreen or slideshow/widescreen for slides and libraries that assume specific values for a slide’s drawing area.
