If any pixels in the manually processed raw image end up
saturated (>255), this causes an error. I've now manually
clamped the values between 0 and 255 to fix this.
It would probably be a good idea to warn when this happens,
as it does mean we're losing data.
I've replicated more of the camera pipeline in the images
saved during scans - in particular, I've added the colour
correction matrix (increases saturation) and the contrast
agorithm (implements gamma correction).
This slows down saving to ~0.5-2 seconds, but that's still less time than it takes to move.
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.
