Crate zenith_render 

CPU PNG reference renderer for Zenith.

Owns the raster backend adapter trait (tiny-skia is the first engine), deterministic PNG production from a scene display list, SVG and raster image decode, glyph rasterization, and enforcement of all raster-time determinism rules. Backend types never appear in the public API.

Structs

PdfOptions

Options controlling PDF emission.

RasterImage

A rasterized image in straight-alpha RGBA8 format (row-major).

RenderError

An error produced by the rasterization or encoding pipeline.

TinySkiaBackend

CPU rasterization backend backed by the tiny-skia library.

Traits

RasterBackend

Trait that abstracts over different CPU rasterization backends.

Functions

composite_spread

Composite two rasterized pages SIDE BY SIDE into one image with an optional transparent gutter between them.

render_image

Rasterize scene to a RasterImage (straight-alpha RGBA8 pixels).

render_pdf

Render scene to a deterministic vector PDF (a single page).

render_pdf_multi

Render scenes (one per document page, in order) to a single deterministic multi-page vector PDF, sharing one sequential object-id space.

render_pdf_multi_with

Like render_pdf_multi but with explicit PdfOptions.

render_pdf_with

Like render_pdf but with explicit PdfOptions (e.g. font subsetting).

render_png

Rasterize scene and encode the result as PNG bytes.

render_spread_png

Rasterize two scenes (left, right), composite them SIDE BY SIDE via composite_spread, and encode the result as deterministic PNG bytes.
