rpptx-layout

rpptx-layout resolves PresentationML inheritance into renderer-ready slides. It combines slide, layout, master, theme, placeholder, relationship, and resource state into owned shapes with concrete visual properties.

Capabilities

Slide, layout, master, theme, and placeholder inheritance.
Concrete shape styles, backgrounds, transforms, and geometry.
Text, bullets, spacing, autofit, and script-aware fonts.
Tables, source-scoped media, charts, links, and timeline evaluation.
Nested groups, connectors, SmartArt text, comments, notes, animations, and source-scoped relationships resolve into one owned slide model.

Use it when

Use this crate when resolving slide, layout, master, theme, and placeholder state into a renderable slide model. Use rpptx for complete deck operations.

Relationship

It sits between rpptx-oxml and rpptx-render. It does not own package I/O or emit final PDF or raster output.

Example

use rpptx_layout::{FlattenedSource, ScopedMediaIds};

let media = ScopedMediaIds::default();
assert_eq!(media.get(FlattenedSource::Slide, "rId1"), None);
