I've swapped `capture_jpeg` for `capture_array`. This will acquire a raw image and process it manually. Currently I've included LST correction, colour balance, but **not** the colour unmixing matrix. In the future we could add this to implement proper correction for saturation.
Currently EXIF data does not seem to be working properly.
Removed maximum scan size of 750 images
Save json of scan inputs and use it for future stitching (ensures consistent parameters)
Moved looping autofocus to autofocus thing from recentering thing
Rewrote looping autofocus to skip unneeded moves, as if peak is out of range, no need to nicely focus
Previously, zip files were only downloaded if they already
existed. Now, they are created with an action, then
downloaded from the result.
Chrome now insists on downloading the files as `output.zip`, I can't see why this has changed, but perhaps it's related
to the security warning. This seems to be specific to zip files.
I've swapped out various `logging.exception` calls for
`logging.error` with `exc_info` set to the exception.
My reading of the docs is that the two shoulld be equivalent,
but the former fails with an error related to
message formatting, as if there was an extra (or missing) '%'.
I've changed the format of the downloaded zip file, so that it
now puts the stitched images at the top level (if they exist).
I've also modified the time of the last stitched image so it
returns None if it doesn't exist - this avoids HTTP errors in
the client.
There's now an action that will save all settings to disk.
This copies code from `labthings_fastapi.thing_server` so
may want to be deduplicated in the fullness of time.
Removed an unnecessary `Optional` and removed the `scan_` prefix from scans that have a non-empty name.
I also added a closing ` to a logging statement.
UUIDs don't serialise to JSON, so I'm now saving it as a plain
string and reconstructing a UUID object when it's returned.
Returning a UUID seems clearer than returning a string.
I now define the variables needed in the finally: block at
the very start, so I can test if they are None.
I've reordered the final move so it can happen as we are awaiting the background processes. I've added exception handling so this won't cause problems with the lock.
We've removed the initial double-autofocus (we just do a
single looping autofocus at the start), and now only do 3 retries rather than 5 if the focus is rejected.
