pcot - 0.9.0-alpha 2025-02-17 GODOLPHIN HILL

• New system for node parameters - the TaggedAggregate system. All nodes updated to this where it makes sense.
• Batch runner (pcotbatch) first draft, which allows a graph to be run from the command line with inputs and nodes able to be modified with a text file, and outputs able to be captured and saved.
• Complete rewrite of manual register node
• "PARC" input and output file format - allows multispectral images with uncertainty to be stored (and other data types too)
• Various bits of refactoring
• Issue fixes
• Yet more tests
• Nodes are now created by left-click dragging from the palette
• Nodes which have been renamed from their defaults have their name text shown in bold
• Forced to downgrade minimum Python version to 3.9 temporarily

pcot - v0.8.0-alpha FENTON SAURUS

• 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

pcot - v0.7.0-alpha EAST PENTIRE

• 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

pcot - v0.6.1-alpha DYNAS COVE

• Multifile input can accept BMP files
• Better multifile documentation
• Filter specifications are no longer hardwired and are loaded from CSVs
• PANCAM and AUPE filters are default filter sets loaded in
• Others can be specified in a config file (and can override PANCAM and AUPE)
• Filter set no longer required by PDS4 input

pcot - v0.6.0-alpha DRIFT STONES

• uncertainty and error bit propagation in expr and all nodes
• Testing quality and propagation rules
• 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

• Annotations (ROIs, legends) are now drawn onto the canvas rather than the image
• Export to PDF, SVG and PNG with those hi-res annotations
• gradient is much simpler, can overlay onto the image and can draw a legend

pcot - "fix" temporarily disabling undo

Regression in undo - as a temporary fix, disabling the undo mechanism (simply by having Document.undo do nothing). Apologies.

pcot - Very early internal pre-release

This version adds: * Undo/redo * improvements to spectral plots * Zadeh operators (easy to do, might be handy) * memory leak bug fix * ellipse detection * Hugo-based doc system, currently for my own notes but may be expanded

pcot - Very early internal pre-release

Very early pre-release version, intended for internal use only - the Aberystwyth team and a few invited external staff. There are expected to be bugs here - please create an issue for each bug using the "issues" tab above.

A few minor things have changed since then, mainly to do with how autorun works, but they should affect anything major.
