Saving default to local storage has a problem:
if you have ticked "scan", the section is not
visible by default so it's easy to start a scan
by accident. I've now forced it to be open if
the scanCapture checkbox is true.
The code checks for the camera-stage mapper matrix by looking at its truth value.
However, this is ambiguous because the matrix has many elements. That means that
if it's missing, we get the expected result, but if it's present
we get an error.
I have avoided dict.get() and instead look it up with [] notation.
This will raise a KeyError if it's missing, which I
handle helpfully.
If the key is present but the value is not castable to an array, we'll
get an exception anyway.
adjust_shutter_and_gain_from_raw now uses a simpler algorithm.
The code is longer overall but hides some details in fuctions.
I've also split the loop into one for shutter speed and one for gain.
This isn't the algorithm that I originally wrote, but it seems to
work and is more readable.
GPU preview and MJPEG stream settings are now persisted
using localStorage. The old code that disabled
the stream for local connections now
just sets the initial/default value.
The initialisation of stream settings is now done
in the created() method of streamContent.vue.
I've eliminated the "globalsafetogglepreview" event
in favour of watching the store.
I've changed the default values in MoveStageAPI
so that it correctly handles absolute moves with missing axes.
I've also simplified it so it isn't using axes_to_array as that
resulted in a confusing code path.
I don't know why these didn't fail before - possibly because of
incomplete type information from old numpy...
I removed a few annotations because they were failing (e.g.
np.sum can return a scalar or an array), but I don't think
this should be a problem - the function inputs and return values
are still typed.
numpy 1.20 deprecates np.float, which was only ever an alias for
``float``. I've replaced all occurrences of np.float with float, as
recommended. There should be no change in functionality.
More or less everything is now done by setup.py
Pipfile simply installs the module in editable mode, which
recursively resolves dependencies as defined in setup.py.
Reset tour button resets the local storage used to mark the tour
as done.
Overriding the origin can now be done with a query string.
This will load the store with the new origin from the start,
so might be better for testing some things.
I'm not worried about unexpected bugs, as it is quite obvious
from the URL what's going on.
Specifying overrideOrigin in the URL now
sets up the store with the modified origin.
This is intended for development, and makes it
much less annoying to develop with a Vue dev server.
The picamera object isn't thread safe; I have now wrapped all access
in context managers that acquire the BaseCamera.lock
I also added an endpoint to reset the LST without auto-gain.
When testing the UI I noticed that the different recalibrate routines
don't use locks properly, so they try to run
concurrently.
This commit isn't tested yet...
I've added buttons to perform the separate calibrations (gain, AWB)
under the full recalibrate link.
It would be really nice to have a modal dialog though.
I also increased the precision of the numbers, which makes the step
buttons annoyingly useless but allows floating point
values without validation errors.
The previous "auto calibrate" button for the camera relied on a
combination of the built-in autoexposure/AWB and
some JPEG-based tweaks to get the exposure settings right.
This often led to confusing results, e.g. oscillating between green and
pink images.
I have rewritten the auto-exposure code to adjust gain and shutter
speed based on the raw image. This seems to be
very reliable, at the expense of being quite slow. That's a price I'm
happy to pay.
I have replaced both the camera's auto white balance and my
JPEG-based AWB hack with a single-shot AWB method that
looks at the raw image.
The scan API view now uses a schema with validation
constraints to enforce a minimum size of 1 in any dimension.
This requires better error handling in the app, which I've added.
It also needs a fix in LabThings so the error propagates correctly
