TL;DR: The Artboards to Files dialog's "File Type:" list now has BMP, JPEG, PDF, PSD, Targa, TIFF, PNG-8 and PNG-24 in the reference application's order, with PSD chosen when it opens, and each of them writes the right file.

Closes #13635
Part of #13628 (EPIC-ARTBOARDS-TO-FILES)

What changed

• Dialog (crates/ui-egui/src/menus/view_cmds/dialogs.rs): the file.export.artboardsToFiles branch is split from Layer Comps to Files. Its field reads "File Type:", lists BMP, JPEG, PDF, PSD, Targa, TIFF, PNG-8, PNG-24 (values bmp, jpg, pdf, psd, tga, tiff, png8, png24) and opens on PSD. Layer Comps to Files keeps its list and its png default.
• Command (crates/engine/src/cmd/artboard_cmds.rs, artboards_to_files): format now also takes
  • png8: one indexed (palette) PNG per board, with the PNG-8 settings Generate Assets already uses (selective palette, no dither, transparency kept);
  • png24: a truecolour .png (with alpha when the board is transparent). A Grayscale or other non-RGB board is converted to RGB for it;
  • targa (same as tga): a .tga file;
  • pdf: one multi-page <prefix>.pdf, one page per board, bottom artboard first, each page sized to the board's pixels at 72 ppi. It reuses Artboards to PDF's writer (raster_pdf); the page encoding moved into a small shared jpeg_page helper, so Artboards to PDF's output does not change.
• Scripts and agents still get png when they leave out format. The params doc lists the new values. An unknown format still returns an error and writes nothing.
• crates/ui-egui/src/export_quality_tests.rs: one line. alt_reset_restores_the_custom_quality checked that Reset brings back the old opening format png. It now expects psd.

Reference behaviour followed (from the issue)

• Labelled File Type:, entries BMP, JPEG, PDF, PSD, Targa, TIFF, PNG-8, PNG-24 in this order, no separators, PSD on first open, the list opens below the field.
• PDF (Multi-Page Document): one <prefix>.pdf, bottom artboard first, MediaBox = the board's pixel size at 72 ppi, JPEG (DCT) images.
• The issue lists some cases as not measured: PNG-8's palette and interlacing, other Targa depths, the other PDF modes, and Layer Comps to Files' list. These keep today's behaviour.
• Not in this PR: remembering File Type after a successful run. The dialog doesn't remember any of its fields yet. MISSING-FEATURE-ARTBOARDS-TO-FILES-EXPORT-OPTIONS #13636 (Export Options) needs that too, so it fits better in one shared change.

Tests

• crates/engine/src/cmd/artboard_cmds/file_types_tests.rs (7 tests, the issue's 800 x 400 document with Red, Blue and Empty boards at 300 ppi):
  • PNG-8 files are indexed PNGs (IHDR colour type 3), and red stays red.
  • PNG-24 files are truecolour, and the transparent board keeps its alpha (type 6).
  • A Grayscale document's boards are still truecolour as PNG-24 (with alpha where transparent). Plain png keeps writing Grayscale. This is from review; the test fails without the RGB conversion.
  • tga and targa write .tga files that read back at the board's size.
  • PDF writes exactly one file with 3 pages and DCT images. The MediaBoxes come in Red (200 x 150), Blue (200 x 200), Empty (100 x 100) order, at 72 ppi even though the document is 300 ppi. A prefix names the file.
  • Leaving out format still writes .png.
  • An unknown format (xyz, png9, "") is an error and writes nothing.
• crates/ui-egui/src/artboards_to_files_types_tests.rs (kittest, 3 tests):
  • The dialog opens on psd with the eight values. The combo box labelled "File Type:" shows PSD. A click opens the list, which shows the eight names top to bottom in the reference order.
  • OK with PNG-8, PDF and PSD writes indexed PNGs, one PDF and PSDs.
  • Layer Comps to Files keeps png and its old list.
• Mutation check: with the production changes to artboard_cmds.rs and dialogs.rs reverted and the tests kept, 6 of the 9 new tests fail. The 3 that still pass check behaviour this PR keeps on purpose: the png script default, the error for an unknown format, and Layer Comps to Files' list.

Checked in the app

I rendered the real dialog offscreen with the snapshot example (File > Export > Artboards to Files on the issue's document):

• the row reads "File Type:" and shows PSD;
• clicked open, the list shows BMP, JPEG, PDF, PSD, Targa, TIFF, PNG-8, PNG-24, opening below the field.

The control channel refuses this export (it writes to ambient paths), so I checked the written files in the tests above, not by clicking OK in the app.

Gate

Ran on the Linux build box:

• cargo clippy -p photocraft-engine -p photocraft-ui-egui --all-targets -- -D warnings, cargo xtask layers, cargo test -p photocraft-engine --test panic_hunt -- --ignored and cargo xtask wasm pass.
• cargo nextest run -p photocraft-engine -p photocraft-ui-egui --lib --tests --no-fail-fast: 12418 passed and 7 failed. None of the 7 is in code this PR touches:
  • Five font and translation tests (burn_bar_tooltips_tests x2, levels_channel_popup_keeps_custom_names_verbatim_in_italian, the two cjk_fonts tests) fail the same way in many other branches' runs on that box.
  • file_open::tests::files_dropped_with_no_document_open_all_open and file_cmds::tests::batch_override_open_follows_called_conditional_and_script_steps fail locally on this PR's base (fc7e37650d) without this change too.

cargo fmt --all --check passes locally. No command was added, so docs/parity-checklist.md doesn't change.

Merge Risk: Minimal · up to 806b8

Artboards to Files now offers the eight file types with PSD as the default, and PNG-24 export of grayscale documents is reported fixed with a test covering it. Remembering the selected type is deferred to a separate follow-up. No merge-blocking risk is identified.

Full details: Title check

Explanation

The title names the Artboards to Files File Type list and says it matches the reference application, which is the main UI change in the changeset. The dialog branch in dialogs.rs now lists BMP, JPEG, PDF, PSD, Targa, TIFF, PNG-8, and PNG-24 in reference order with PSD as default. The engine command, tests, and docs also support the new formats, but the title focuses on the dialog list, which is the primary user-facing change. The title is specific and accurate. The issue reference (#13635) is also consistent with the linked issue.

Full details: Linked Issues check

Explanation

Directly linked issue #13635 coding requirements are covered by the reviewed head, as shown by the current PR summary and the PR description. The dialog section of the summary (dialogs.rs) gives a separate Artboards to Files branch with the label 'File Type:', entries BMP, JPEG, PDF, PSD, Targa, TIFF, PNG-8, PNG-24 in order, and PSD as the default. The command summary (artboard_cmds.rs, artboards_to_files) covers png8 (indexed), png24 (truecolour, alpha kept), tga/targa (.tga), and pdf (one multi-page <prefix>.pdf, bottom board first, 72 ppi page sizes, reusing raster_pdf). Missing format still defaults to png. Unknown format values return an error and write nothing. The params doc lists the new values. Layer Comps to Files keeps its list and png default (dialogs.rs summary and a kittest). Tests cover these behaviours in file_types_tests.rs (6 engine tests) and artboards_to_files_types_tests.rs (3 kittest tests). Limits: the incremental diff from ff60e13 to 806b851 could not be read (changed blobs missing from the checkout), and the dialogs.rs file read was truncated before the artboards branch. This verdict therefore relies on the current summary and PR description. Remembering File Type after a successful run is in the issue's reference notes but not in its Done-when list, so its absence does not fail this check.

Full details: Out of Scope Changes check

Explanation

All changed areas connect to #13635 or follow directly from it. dialogs.rs: the Artboards to Files branch split and the Layer Comps branch kept. artboard_cmds.rs: the new formats, the params doc, and the test module registration. file_types_tests.rs and artboards_to_files_types_tests.rs: the tests the issue requests. lib.rs: test-module registration for the new UI test. export_quality_tests.rs: one line that moves the Alt+Reset expectation from png to psd, which follows from the requested PSD default. The shared jpeg_page helper used by Artboards to PDF is a reuse refactor that the issue allows. Its output is stated as unchanged but was not independently verified. This is a residual uncertainty, not a finding. The incremental diff from the previous reviewed head could not be read, so changes between ff60e13 and 806b851 are not independently checked. No unrelated behaviour change was identified in the available evidence.

29-33: Trivial · Maintainability & Code Quality · Low value

Use tempfile::TempDir for the test output directory.

out_dir removes its directory only after the test's assertions pass. A failed assertion leaves the PID-named directory in the temp folder. Later runs use a new PID, so they do not reuse or remove it. The sibling test in image_processor_formats_tests.rs uses tempfile::tempdir(), which removes the directory when its guard drops, including during unwinding. Return a guard from the helper and keep it alive for the test body.

Suggested helper change

-fn out_dir(tag: &str) -> String {
-    let dir = std::env::temp_dir().join(format!("photocraft-13635-{tag}-{}", std::process::id()));
-    let _ = std::fs::remove_dir_all(&dir);
-    std::fs::create_dir_all(&dir).unwrap();
-    dir.to_string_lossy().into_owned()
+fn out_dir(tag: &str) -> tempfile::TempDir {
+    tempfile::Builder::new().prefix(&format!("photocraft-13635-{tag}-")).tempdir().unwrap()
 }

Each caller that uses the returned value as a String should call dir.path() and keep dir in scope until the test ends. Remove the explicit remove_dir_all calls.
