File → Print… (⌘P) opens the Print module as a dialog: settings on the left,
the page drawn to scale on the right with the photos as they will print (fit
or Zoom to Fill, turned by Rotate to Fit, Photo Border, Inner Stroke, page
background).
Settings column: templates (save, apply, delete), layout style, image
settings, grid / package cell controls (standard and custom cell sizes, Auto
Layout, New Page, Clear Layout), rulers and guides (units in/cm/mm/pt, snap
off/cells/grid, grid size, margins, bleed, page grid, image cells,
dimensions), page setup (paper, orientation, margins), page background and
the print job.
Preview: rulers in the chosen unit, dashed margins and bleed, page grid,
dimension labels, page navigation. In the package styles cells are selected,
dragged (print.cell.move) and resized from a corner handle
(print.cell.resize) with the guides' snapping, arranged from the inspector
row or a context menu, and given a photo (Custom Package). Every change is a
print.* command; the drag is measured from where the pointer went down so
the click-versus-drag slop is not lost.
Print to PDF… picks a file and renders on a background thread with an
activity-stack row, cancellation and original protection, like the contact
sheet, which keeps working unchanged.
Headless tests drive the dialog with real pointer input through the control
channel (print:cell:N, print:resize:N, button:print*): styles and checkboxes,
add / drag / resize / arrange / delete, snapping to a neighbour, Auto Layout
and pages, templates, the PDF, the activity row, and that the dialog and its
buttons fit the window.
The Print module's state lives in the session (Session::print), so the app,
CLI, control channel and MCP share one print: layout style (Single Image,
Contact Sheet, Picture Package, Custom Package), page setup, grid, image
settings, page background, guides and job. 18 commands, none journaled
(nothing here touches the catalog):
print.get / set / reset set merges a partial patch, validates the whole
result and changes nothing on error; a new
paper or margin pulls cells back inside
print.cell.add|move|resize|delete|stack|photo|page
print.layout.autoLayout|newPage|clear
print.exportPdf {path, ids?} composes and writes the PDF with an activity
row, refuses to replace an original
print.template.list|save|apply|delete
Templates keep layout, image settings, page and job (not the photos assigned
to cells, not the guides) and are saved in the library's prefs.json next to
the export presets. They are stored as JSON and checked when applied, so a
template from another version or a hostile one is an error on use and never
makes the preferences file unreadable.
Tests drive every command through the dispatcher (hostile numbers, unknown
keys, caps, persistence across reopening a library) and a CLI end-to-end test
chains set / add cells / Auto Layout / PDF in one run.
print/compose.rs turns a layout and its photos into PageRasters: 16-bit
interleaved RGB encoded in Rec. 2020 at the job's pixel density. Each cell's
photo is rendered with the export pipeline at exactly the size the cell needs,
then fitted (whole photo, centred) or zoomed to fill (centre crop), turned a
quarter clockwise when Rotate to Fit makes it print larger (or crop less),
framed by the Photo Border (package styles only) and finished with the Inner
Stroke drawn inside the photo edge. The page background, border and stroke
colours are given in sRGB and converted to the page encoding.
Photos go to cells by layout style: Single Image and Contact Sheet paginate
the selection, Picture Package repeats the first photo, Custom Package prints
each cell's own photo. The job is prepared on the session and run off it with
progress and cancellation, like the contact sheet; page and job pixel counts
and page counts are capped so a hostile resolution or paper cannot exhaust
memory.
print/output.rs holds the interim PDF writer (Rec. 2020 to 8-bit sRGB JPEG
pages sized to the paper in points) through the contact sheet's Pdf, now
pub(crate). PrintJob carries the print resolution (72 to 720 ppi, 240 default).
Tests draw on synthetic images for exact pixels (borders, strokes, crop,
rotation direction, resampling) and on the demo library for whole pages.
crates/engine/src/print/layout.rs is the pure page model the Print module
builds on: ten named papers plus custom, orientation, margins and the
printable area; Single Image, Contact Sheet (grid with spacing and square
cells), Picture Package and Custom Package styles; package cells with a
stacking order (send to back / backward / forward / bring to front); a
deterministic MaxRects packer behind Auto Layout (largest first, earlier
pages filled before a new one opens, a cell turned a quarter only when it
fits nowhere as given); snap-to-cells and snap-to-grid helpers; ruler units
and guide options.
All lengths are inches in page space, after orientation. Every number from
outside is checked (NaN, infinity, negative, oversized, cell and page caps)
and Layout::validate guards saved layouts.
No command or UI reaches it yet, so the parity rows keep their status.
On merge: the HDR histogram is applied in develop_reporting (#712 split develop), is skipped for
draft renders (a second render per drag tick), and HdrBins::bin clamps a hand-built split so it
can't underflow (test hdr_bins_with_any_split_stay_in_range).
photo.editExternal takes the selection (or ids, at most 50): each photo gets its own -Edit copy
stacked on its original, the copies are selected and returned in copies (path / id / original
still name the first). Photo ▸ Edit In opens each copy in the editor.

On merge: Lightroom's default profiles (Adobe Standard, Adobe Color), named by nearly every sidecar,
give no camera-profile warning; other profiles still do (test default_lightroom_profiles_are_not_reported).
The import help string keeps main's onDeleted wording and gains warnings.
On merge: the quick preview path orients like the whole-file path (preview_orientation with the
raw's header prefix, so a portrait raw whose embedded JPEG carries no orientation is not sideways),
and its doc links point at preview_window.
Turning on AI Denoise without a model opens Settings > AI Denoise and
keeps a pending request, so the switch showed checked and Settings
offered "Cancel pending action". Closing the setup with no model
download or installation running now drops that request: the switch
goes back off and nothing claims to be pending. A download started
before closing still turns AI Denoise on when it finishes.

File > Import Profiles & Presets... now builds one toast for both halves
(a second toast replaced the first, so a .cube-only import said "No new
presets"). The preset half is skipped when no preset files were picked,
and profile.import's failures are shown with their reason. profile.import
also reports .cube files and zips it couldn't read instead of dropping
them silently. The command's result carries the profile half under
"profiles".

On merge: metadata.downloadPlaceNames accepts plain http only for the loopback address itself
(http://127.0.0.1.example.com/ and http://127.0.0.1@host/ are refused; test
download_base_is_https_or_loopback_only).
