More unit tests
colour connector "swatch" generator script
started work on dark/flat field generator
Datum archives - a file format (.PARC) for saving Datum objects, with an associated input method and exporters. Required because we have no other way of saving images with uncertainty and DQ.
DatumStore class wraps Archive objects so we can store Datum (this is used for the datum archives)
expr uses a DataWidget, as does TabData.
1D vectors supported as a Datum.NUMBER type. Modifications made to datumfuncs and operators permit this. Notably, the semantics of mean, sd, sum, min and
square bracket parsing in expressions generates vector-creation and vector-index instructions max have changed to operate band-wise and generate a vector when performed on images.
Multiband extraction, e.g. a$[640,550,440].
.bands property generates a vector of wavelengths, so we can do a$b.bands, to get the bands in a that are also in b, in the same order as in b.
.u property
properties graph tests and QoL work for test building
precedence adjustments in expressions
getSelection in document can help get selected nodes in plugins
serialiseFields does a deepcopy - fixes undo bugs
fixes to roiexpr; it no longer keeps UI data in the node so undo works better
Cookbook in progress, but not part of the main repository to allow it to be updated more frequently
First release for Zenodo

Very many more unit tests
Bug fixes
Complete rewrite of spectrum system, using the SpectrumSet object
Multidot now does painted regions and floodfill
Joseph's PCT detector outputs image with ROIs
Dump removed and sink enhanced
TabData shows sources
Inputs decoupled from Sources - Sources now use composition, not inheritance
Comment box for nodes removed (it was never used)
Direct multifile loading
Direct PDS4 loading - required refactoring of entire PDS4 layer
Direct ENVI loading
Raw file loading from mono images supporting lots of formats
Loader presets for multifile
Operator overloading on Datum objects
The "datumfunc" system replacing hand-registration of functions
flip and rotate functions (datumfuncs)
String datum objects and strings usable in expr
Docs on library usage
Changes to nodes so that slow nodes can be disabled and very slow nodes start disabled. This functionality existed before, but was "ad-hoc"
Document.changed() is now Document.run() and forces disabled nodes to run
Most nodes now store data in their outputs rather than a "node.out" which is then written to an output
Changes to multidot - doc improvements, UX and bug fixes

uncertainty and error bit propagation in expr and all nodes
Testing quality and propagation rules (see Principles)
Test graphs for nodes and other high-level functionality
Test nodes for those graphs
Tabular output on spectrum and histogram nodes
Gen node for test patterns
Refactoring of Datum
Utility nodes - e.g. roidq for generating an ROI from DQ bits
Output enhancements
- Gradient node can export to PDF
- Annotations (e.g. text labels) are now drawn on the painter at high res, and have been refactored hugely
- Annotations use thickness zero by default (the Qt "cosmetic" thickness)
PCT detector node
ROI negation and refactoring of operators
roiexpr node for composing ROIs using expressions
Crude band depth node (needs work)
A lot of bug fixes and regression fixes

Open source!
PDS4 importer with proctools
Ad-hoc Spectrum viewer in canvas
Significant rewrite of expression execution code, permitting custom types to have operations defined on them
Direct input method for library use
Improved default RGB mapping in canvas
Testing
- Basics testing
- Testing of the operating principles (see Principles)
  - Source rules
  - ROI rules
rect node can now be edited numerically
circle node can add circular ROIs, which can be edited numerically.

"pixel scanning" on canvases, shows spectrum of pixel when active
custom cursor, pixel under cursor highlighted at high zooms
text toggle button (currently unused)
fixes to example plugin
added macos.spec for pyinstaller
archive system shows progress when loading each archive element
Issue 1 fix (multiple tab closes when main window reinitialised)
dynamic type determination for expr output
can connect incompatible node outputs to inputs; indicated as red arrows
infinite recursion in ROI nodes fix
splash screen for Windows/Linux pyinstaller startup (not yet supported on MacOS pyinstaller)
custom Datum and connection brush types now easy
expr resizing regression fix
multiple input buttons after load/resize fix
status bar repaints on ui.msg, so it's updated in load and perform
context menu on editable text caused a crash (bug in Qt). Workaround.
