* M2: clip intersection starts its row walk at the first shared row clip::intersect in vello_common, the step every clipped path passes through, began its walk over strip rows at the earlier of the two paths' first rows. Each path therefore visited every row above it, although rows where one path has no strips produce no output. Every page is clipped (the crop box is a clip), so this ran for every stroke of every render: on the A1 engineering sample it was the hottest function in a full-page render. Start at the later first row, as vello_common 0.1 does. The strips and the pixels are unchanged; a test counts the rows the walk visits and fails without the change. vello_common 0.0.8 is vendored with that one-line PdfCraft patch (marked in the source), its unit test, the vendor/README.md row and an ATTRIBUTION.toml entry for its reference image. Cargo.lock records it as a path crate.

|
|
|
|
//! This crate includes common geometry representations, tiling logic, and other fundamental components used by both [Vello CPU][vello_cpu] and Vello Hybrid.
|
|
//!
|
|
//! # Usage
|
|
//!
|
|
//! This crate should not be used on its own, and you should instead use one of the renderers which use it.
|
|
//! At the moment, only [Vello CPU][vello_cpu] is published, and you probably want to use that.
|
|
//!
|
|
//! We also develop [Vello](https://crates.io/crates/vello), which makes use of the GPU for 2D rendering and has higher performance than Vello CPU.
|
|
//! Vello CPU is being developed as part of work to address shortcomings in Vello.
|
|
//! Vello does not use this crate.
|
|
//!
|
|
//! # Features
|
|
//!
|
|
//! - `std` (enabled by default): Get floating point functions from the standard library
|
|
//! (likely using your target's libc).
|
|
//! - `libm`: Use floating point implementations from [libm][].
|
|
//! - `png` (enabled by default): Allow loading [`Pixmap`][crate::pixmap::Pixmap]s from PNG images.
|
|
//! Also required for rendering glyphs with an embedded PNG.
|
|
//! Implies `std`.
|
|
//!
|
|
//! At least one of `std` and `libm` is required; `std` overrides `libm`.
|
|
//!
|
|
//! # Contents
|
|
//!
|
|
//! - Shared data structures for paths, tiles, and strips
|
|
//! - Geometry processing utilities
|
|
//! - Common logic for rendering stages
|
|
//!
|
|
//! This crate acts as a foundation for `vello_cpu` and `vello_hybrid`, providing essential components to minimize duplication.
