The info panel gains a line under the lens: "Adobe Standard · in the
file", the .dcp it came from, "· off" when the photographer switched it
off, or "No camera profile · matrix only" — the ordinary case for a
CR2, worded as a fact rather than a failure. A DNG whose embedded
profile may be copied, for a body with no installed profile, also gets
"Use this profile for every Canon EOS 6D →", which saves it into the
profiles directory; the body's CR2s render through it from their next
decode.
The profiles directory is <data>/profiles, read at start-up on desktop
and Android before anything decodes. The library open path never set
the lens line; it now sets both. Labels: Camera Profile, Use Profile,
Look Amount.
A 22927×8966 Lightroom panorama opened as its embedded preview with
develop withheld, because no texture could hold it. DevelopSession now
opens a linear DNG past PROXY_EDGE (8192) on a box-reduced copy, and
keeps the full resolution on the CPU. The canvas at fit, the thumbnail,
the histograms and the masks work from the copy; a render finer than
it — the canvas zoomed in, a tile of the export — samples a window cut
from the full resolution, kept while the view stays inside it. The
export renders in halo-grown tiles of 4096 and assembles them.
On the panorama: decode 1.6 s, open 210 ms, canvas 37 ms, a zoomed
window 130 ms, the full-size export 5.9 s.
A preset could not choose a film stock. The stock is a choice of material
rather than a parameter, so `Preset` — a map of `op.param = value` — had
nowhere to hold it, and "Portra 400, printed" could not be saved, copied
or shipped as a look. Worse, the film node's own sliders *were*
parameters: a paste moved one stock's exposure and push onto whatever
stock the target was on, and left the target's tables baked from the
values it had just replaced.
A preset now carries a `FilmRef` beside its parameters. It travels under
whichever scope carries the film node, so the stock and its sliders are
never split, and by the replacement rule every other parameter follows:
applied at that scope, a preset without a film develops the target
without one. `Preset::apply` returns the `FilmRebake` it owes, as
`EditGraph::set_state` already did, because this crate cannot bake a
stock; the develop session pays it before recording the step, and the
batch paste writes the stock into each sidecar through `film_for`. The
library file spells it `film =` / `film_print =`, as a sidecar does, and
an older build keeps those lines as ones it does not understand.
`EditState` keeps the film in its own field only: the parameters it
captures leave it out, so one edit has one place to say which stock it
is on.
Second, a preset now has a reach. Replacement is right for a copy of a
whole edit — "make these match" — and wrong for a look: a stock-only
"Portra 400" applied that way would put the photograph's exposure, white
balance and noise reduction back to default. `Reach::Named` replaces only
the operations a preset names (whole operations, so a look that sets the
blacks resets the whites beside them) and the film only if it names one.
Saved edits and the clipboard keep `Reach::Whole`; the line `reach =
named` is written only for the other, so existing libraries write the
same bytes.
Cropping tighter past a mask layer made it invisible without a word:
the layer stayed in the panel and the sidecar, and its adjustment went
on landing on pixels nobody would see again.
When a crop is let go, develop now measures what the gesture did to the
mask stack (dr_pipeline::orphan) and, if any layer is now entirely or
mostly outside the frame, shows a notice over the photograph: how many
layers, their names, "Undo crop" and "Keep crop". The crop is already
applied and nothing waits on the answer.
The crop overlay gains a release callback carrying the rect the press
began from, so the measurement runs once per gesture and never on the
drag's per-frame changes. Choosing a ratio is measured the same way,
being a crop committed in one click.
"Undo crop" is the ordinary undo, and the notice is tied to the history
revision it was raised at: the redraw that follows any history move
clears it, so the crop and its warning go back as one step. A second
drag folded into the same step is measured from where that step began.
A crop that strands nothing shows nothing.
develop.rs had grown to 9,327 lines covering everything the develop
session does: opening a photograph, the parameter-row and curve-widget
panel model, mask viewing and editing, mask creation and the rasteriser
that turns a mask stack into GPU arrays, spot repairs, scene
segmentation, framing and zoom, white-balance sampling, rendering and
film choice, and the undo/snapshot history. docs/dev/code-health.md
CH-1 names dr-ui's lack of a view layer as the reason every feature
kept landing in a handful of files; this is the first of the two pure
splits it recommends as easy, no-behaviour-change wins independent of
that larger rework.
The boundaries follow the file's own sections (several were already
marked off with comment headers) and the seams a full read turned up
underneath them -- mask storage/rasterisation turned out to be a
distinct concern from mask viewing and editing, and rows/tabs/curves
from each other, so those split further than the headers alone
suggested. Each module stays under about 1,500 lines. Struct fields
and the handful of helper methods now called from a sibling module
became `pub(super)`, which is strictly narrower than the whole-crate
reachability a single file gave them; nothing gained visibility outside
`develop`. Tests moved with the code they test, including the few
cases where a helper one file's tests needed was itself only defined
in another's -- those became shared fixtures in `mod.rs` alongside the
`headless`/`read_back`/`grey_session` helpers that already worked that
way. `mod.rs` re-exports every item `develop::` callers outside this
module used before, so lib.rs, masks_ui.rs and the rest needed no
changes.
