The panorama scene now ends in the grid, on the composite in its wide cell beside the twelve frames it was made from, with the thumbnail the merge made: the picture is taken straight after the merge, before any rescan could have found the file. The manual's library section says how a panorama's cell is sized and packed, and its panorama section that the composite is in the grid the moment it is written. panorama.md §9 records the race that kept it out, the catalogue-then-register path that replaced it, how the thumbnail is developed, and the layout's classes.
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.
GIFs are made at 960 px and ten frames a second. A scene whose film does
not compress at that size says otherwise in GIF_SIZE, which record.sh
reads through scenes.py gif NAME. giant_pano borrows a 500 MB panorama
from outside the library (DR_GIANT_DNG, by default
/var/tmp/dr-dng/IMG_4181-Pano.dng) and removes it again, so it runs last.
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.
