photocraft_psd::fixtures (feature testgen) generates the FILE-216-2 fixtures at test time: a 20 MP layered PSD and a 150-layer A4 layout (groups, masks, hidden layers, drop shadows, known merged colours), a 2.02 GB PSD just under Photoshop's cap and the 4-5 GB PSBs, streamed row by row. io tests/large_files.rs opens, checks, saves and re-opens each (the 2 GB PSD and 4.38 GB PSB are opt-in). The ui-egui large_file_bench times opening the big two, wired to P20 and a new P60. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

//! Writes multi-gigabyte PSB files (and the 2 GB PSD) for large-file tests (#375, #216), straight
|
|
//! from the Adobe PSD spec and independent of this crate's writer, so the fixtures don't inherit
|
|
//! its limits. The generator is `photocraft_psd::fixtures` (feature `testgen`).
|
|
//!
|
|
//! `cargo run --release -p photocraft-psd --example big_psb -- <out dir> [case...]`
|
|
//!
|
|
//! Every sample follows `fixtures::sample`, so a reader can check any pixel without the file. RLE
|
|
//! cases keep each row constant (tiny files, full decoded size); raw cases vary along x too.
