dtourolle 5e863fa718 Re-record the manual under the scene-referred pipeline
D19 changed how every raw photograph renders, so every picture was
stale; all forty are recorded again from this tree. Beside the ones
already in the page there is now one for Tone Mapping: an alpine frame
whose clouds sit near white, its White Point raised to bring them back
and lowered for a brighter picture, its Contrast raised, then Before.

The panorama film unticks the first frame and ticks it back, so the
Frames list and the re-solve show; it no longer films minutes of
"Reading the frames", cutting from the first seconds of the job to the
alignment. The manual's presets menu opens beside the rail, not beside
the photograph.

tools/manual — the pictures in docs/manual

record.sh drives the desktop build on a private X server and records the scenes in scenes.py into docs/manual/media/:

tools/manual/record.sh /var/tmp/dr-demo/library              # every scene
tools/manual/record.sh /var/tmp/dr-demo/library develop_zoom # one, and what it needs
tools/manual/record.sh --changed /var/tmp/dr-demo/library    # those whose sources moved
tools/manual/record.sh --check                               # the manual and the scenes agree
tools/manual/record.sh --list

Set DR_LIBRARY_SNAPSHOT to a pristine copy of the library: a recording rates, files and merges, and the snapshot is copied over the library first. Each run starts from a fresh profile under DR_HOME.

Controls by name

The binary is built with --features automation, which lets the app answer "where is the control labelled Exposure?" over the Unix socket named by DR_AUTOMATION (ui/dr-ui/src/automation.rs). No other build has the feature, and a build that has it listens only when the variable is set. The names are the accessible labels a screen reader reads, so a scene says click_on('Select@Button') or slide('Exposure', 24) rather than a pixel, and survives a panel that moves. The pointer itself is still xdotool.

DR_HOME=/var/tmp/x tools/manual/drive.py launch /some/folder   # a feature build in DR_BIN
tools/manual/drive.py labels                 # every name on screen
tools/manual/drive.py click-on 'Settings@Button'
tools/manual/drive.py ids canvas             # things with no name: id:canvas-image
tools/manual/drive.py stop

Grid cells are named by file (_MG_8393@ListItem), rating stars 1 star to 5 stars. What a scene cannot name — a point on the photograph, the crop rectangle's corner — it places relative to something it can (drive.photo(fx, fy), id:move-area).

Scenes and the manual

Each scene in scenes.py declares the pictures it makes, as the manual names them, and the globs of the sources that could change them. --check fails when the manual shows a picture no scene makes, or a scene makes one the manual does not show; it reads two files and runs in CI. --changed re-records a scene when one of its sources, or its own code, has changed since the commit that last touched its pictures.

Two things the scripts know that are not obvious: a Slint TouchArea wants a held press, not xdotool's click; and the app is driven on Xvfb rather than the desktop because under XWayland at scale 2 a pointer warp lands at twice the coordinate asked for.
