Struct RenderOptions 

pub struct RenderOptions {
    pub glyph_painting: GlyphPainting,
    pub substitutes: SubstituteSource,
    pub oc: Option<Arc<OcState>>,
    pub cache: Option<Arc<RenderCache>>,
}

Options controlling a single page render.

Fields

glyph_painting: GlyphPainting

Which font programs the rasterizer will paint.

substitutes: SubstituteSource

Where Full-tier substitution draws replacement faces from. Ignored at every other tier.

oc: Option<Arc<OcState>>

The document’s optional-content visibility (ISO 32000-1 §8.11): content in groups the default configuration turns off is not painted, counted in RenderReport::hidden. The synchronous entry points fill this from the document when it is None; an asynchronous caller builds it itself (e.g. AsyncDocument::oc_state), and leaving it None there renders every layer.

cache: Option<Arc<RenderCache>>

Fonts loaded once for the document instead of once per page: a caller rendering a whole document passes one RenderCache to every page, and each font program — outline parsing included — loads once. None keeps every load page-local. Keyed by the font dictionary’s object reference, so identical resource names on different pages never collide, exactly like text extraction’s FontCache.
