The layers reader of the editing copy (operators translated into PostScript for the interpreter, any file with RGB colours, gradients, transparency or images falling back to its page) is replaced by a reader of the whole structure (import/ai): layers and sublayers with their options, groups, compound paths, clipping groups and layer clipping, names, hidden and locked objects, RGB, CMYK, grey, named and spot colours, gradients, transparency, fill rule, overprint, embedded images with their alpha channel, guides and every artboard, and objects drawn as their look when they have several fills or strokes, effects or a brush. Containers: Zstandard, zlib or plain data in EPS and .ai. The text placement, the comparison with the page and the overwrite guard stay around it. The page's type takes its text object's place without a group; the comparison is by lightness, on nothing, without layers that don't print. Symbols, pattern fills, placed files and unknown operators make the file come in as its page where they show, and are left out of layers that don't.

//! VectorCraft test helpers.
|
||
//!
|
||
//! - [`fixtures`]: sessions and documents in known states (empty, single/multi selection, a "rich"
|
||
//! document touching most node kinds), plus a [`fixtures::DocBuilder`] for building documents
|
||
//! directly (render tests).
|
||
//! - [`strategies`]: proptest strategies for geometry and for engine command sequences ([`strategies::Op`]), and
|
||
//! junk-parameter generators for fuzzing the command registry.
|
||
//! - [`invariants`]: structural checks for documents and sessions, and round-trip checks
|
||
//! (`.vectorcraft`, SVG, `document.inspect`).
|
||
//! - [`raster`]: rendering helpers and image comparison with a perceptual tolerance.
|
||
//! - [`geom`]: geometry assertions (approximate equality, curve sampling, Hausdorff distance).
|
||
//! - [`pdf`]: hand-written PDF files (page boxes, colour spaces, encryption) for import tests.
|
||
//! - [`ai`]: hand-written Illustrator editing data, and the EPS and `.ai` files that carry it.
|
||
//! - [`ase`]: hand-written swatch exchange (`.ase`) files for swatch library tests.
|
||
//!
|
||
//! This crate may only be used as a dev-dependency (enforced by `cargo xtask layers`).
|
||
// Test support only (a dev-dependency of every crate that uses it): a failed setup or assertion
|
||
// must panic, like `assert!`, so the shipped-code ban on panicking (AGENTS.md › Robustness) doesn't
|
||
// apply here.
