File › Open, Other Library… and the User Defined library folder read .ase files. Colors keep their model, global and spot colors stay global and spot, and color groups stay groups. The library readers take a file's bytes. On the web, File › Open passes a swatch library file to swatch.library.load as dataBase64 instead of as lossy UTF-8 text. Swatch and group names in a library are now unique, in .gpl files too. Add to Swatches puts each color group of a library into one document group when the document already has a swatch with the group's name. The library fuzz helpers fail when a command panics.

//! 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.
|
||
//! - [`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.
