Struct Presentation 

pub struct Presentation {
    pub document: Document,
}

An OpenDocument presentation.

Fields

document: Document

The package and everything shared with the other two formats.

Implementations

impl Presentation

pub fn read(bytes: &[u8]) -> Result<Self, Error>

Read a .odp package.

Errors

The bytes are not a presentation, or its content.xml cannot be read.

pub fn slides(&self) -> Vec<Slide<'_>>

The slides, in the order they are presented.

pub fn master(&self, slide: &Slide<'_>) -> Option<&Element>

The master page a slide names.

pub fn background(&self, slide: &Slide<'_>) -> Fill

What fills the ground behind a slide.

The slide’s own drawing-page style first, then its master’s, which is where a template puts the colour or gradient every slide shares. A slide that turns presentation:background-visible off gets neither.

pub fn background_objects(&self, slide: &Slide<'_>) -> Vec<&Element>

The master page’s decorations: what is drawn behind a slide before anything on the slide itself.

A child carrying a presentation:class is left out, because that attribute is what makes a frame a slot rather than a decoration: the slide’s own frame of that class takes its place, and what the master holds is either a prompt or a field. Left in, a slide gains the words Click to edit Master title style and a literal <number>.

The class and not presentation:placeholder, which would be the obvious test and is not written reliably: the title frame on deck.odp’s master carries the prompt text and no such attribute. Measured, not read.

Empty for a slide whose style turns presentation:background-objects-visible off, which is how a template offers a plain slide.

pub fn page_layout(&self, slide: &Slide<'_>) -> PageLayout

The page geometry a slide is drawn in: the size of its master page’s layout.

Every shape’s position is in this space, so a renderer needs it before it can place anything.
