# Changelog
All notable changes to this workspace are documented here. The format follows
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and the crates follow
pre-1.0 [Semantic Versioning](https://semver.org/) (a `0.x` minor bump may carry
breaking changes).
This is a workspace of three crates released together: **siplot** (the plotting
library), **sidm** (a PyDM-style EPICS display layer built on siplot), and
**adl2sidm** (a MEDM `.adl` → SiDM-Rust-source converter).
## [Unreleased]
## [0.4.1] - 2026-07-02
A single-fix patch release: the macOS trackpad-momentum reset bounce-back in
`siplot` (below). `sidm` and `adl2sidm` are re-released in lockstep (no
functional change).
### Fixed — `siplot`
- **Reset Zoom / Zoom Back no longer bounces back under macOS trackpad momentum.**
A view reset (right-click *Reset Zoom*, *Zoom Back*, or reset-to-data) restores
the view while the pointer sits over the data area, but a macOS trackpad /
Magic Mouse keeps sending *momentum* scroll for ~1 s after the gesture ends — so
`smooth_scroll_delta` stayed non-zero and the wheel-zoom handler re-zoomed the
just-restored view on the frames right after the menu closed. Box-zoom leaves no
residual scroll and so was unaffected, matching the reported asymmetry. A new
`Plot::reset_scroll_guard`, armed by every view-reset path (`Plot::zoom_back`,
`Plot::reset_zoom_to_data_range`, and the *Reset Zoom* context-menu item) and
consumed by the single wheel-zoom handler, swallows the decaying momentum until
the scroll settles back to zero, then disarms so a fresh gesture zooms normally.
Non-momentum wheel mice are unaffected: the scroll is already zero the frame
after a reset, so the guard disarms immediately.
## [0.4.0] - 2026-06-16
Post-`0.3.0` deep-audit pass over the `silx.gui.plot` fit subsystem and marker
set: completes every silx `FitManager` fit theory and the last missing marker
glyph. `siplot` only; `sidm` and `adl2sidm` are re-released in lockstep (no
functional change).
### Added — `siplot` fit theories (silx `FitManager` parity)
A FitWidget audit found siplot exposed only **8 of silx's 19 `FitManager`
theories** (`silx/math/fit/fittheories.py`). The missing 11 are now ported,
byte-faithful to silx `funs.c`, each a new `PeakModel` + `FitModelChoice`
variant fitted through the existing iterative path. **All 19 silx fit theories
are now implemented.**
- **Area Lorentz** (`sum_alorentz`), **Split Gaussian** (`sum_splitgauss`),
**Split Lorentz** (`sum_splitlorentz`).
- **Area Pseudo-Voigt** (`sum_apvoigt`), **Split Pseudo-Voigt**
(`sum_splitpvoigt`), **Split Pseudo-Voigt 2** (`sum_splitpvoigt2`).
- **Degree 2–5 Polynomial** fit theories (`fitfuns.poly` / `estimate_poly`),
reusing the numpy-convention `polyfit`/`poly_eval` — distinct from the
polynomial *background* theory.
- **Hypermet** (`sum_ahypermet`): a Gaussian with short-tail, long-tail and step
terms (`tail_flags = 15`, silx's default `HypermetTails`). Tail ratios seed to
silx's `Initial*` CONFIG values; silx's per-tail `CFIXED`/`CQUOTED` defaults
are reachable through the existing per-parameter constraint UI (consistent with
siplot's all-`Free` default-constraint invariant).
### Added — `siplot` markers
- **Heart** (`♥`) marker glyph (silx `HEART`), a cardioid SDF in the marker
shader plus the CPU legend icon — completing all 18 silx marker symbols.
## [0.3.0] - 2026-06-16
This release completes the `silx.gui.plot` 2D parity port (the queue is now
exhausted save for a handful of documented platform/perf residuals) and adds a
full true-3D scene subsystem ported from `silx.gui.plot3d`.
### Added — `siplot` 3D scene subsystem (`silx.gui.plot3d` port)
A full true-3D scene stack ported from `silx.gui.plot3d` onto siplot's
wgpu/egui infrastructure, rendered through an offscreen depth-tested pass that
blits into egui's color-only render pass. Tracked wave by wave in
`doc/plot3d-parity-roadmap.md`.
- **Scene foundation**: a row-major `Mat4`/`Vec3` + `Camera` math layer (look-at,
perspective/orthographic projection, orbit/pan/zoom, `resetCamera`) ported
line-for-line from silx and unit-tested against its values; an interactive
**`SceneWidget`** (left-drag orbit, right-drag pan, wheel zoom) with a bounding
box + RGB axes chrome.
- **3D items**: `Scatter3D` (billboarded point markers), `Mesh3D` /
`ColormapMesh3D` with silx's camera-fixed headlight shading, the
`Box3D` / `Cylinder3D` / `Hexagon3D` cylindrical-volume primitives, and 3D
`ImageData` / `ImageRgba` / `HeightMap` textured-quad items.
- **`ScalarFieldView` flagship**: a marching-cubes iso-surface extractor (silx's
256-case lookup ported verbatim) plus a colormapped cut plane through a
`ScalarField3D` volume, and `ComplexField3D` (a complex field projected to a
real scalar through a shared `ComplexMode`). `setData` frames the camera only
on first data, matching silx `centerScene`-once.
- **Tools / window**: the seven silx **viewpoint presets** with a "View"
drop-down (`viewpoint_menu`) and a `rotate_scene` orbit primitive; a
`ScalarFieldProperties` egui panel (port of `GroupPropertiesWidget`:
cut-plane visibility, colormap, value range, autoscale, per-iso level/colour/
add/remove) with a colorbar reusing the 2D `ColorBarWidget`; a composed
**`SceneWindow`** (toolbar + scene + toggleable properties panel); and an
off-screen **scene snapshot** (`SceneWidget::snapshot` / `snapshot_scene3d`)
reading the rendered scene back as RGBA8 for `encode_png` (the analogue of
silx `grabGL` + save-as-PNG).
- **3D picking + `PositionInfoWidget`**: CPU ray-geometry picking ported from
silx (`PickContext.getPickingSegment` + `segmentTrianglesIntersection`, *not* a
GPU colour-id readback). `SceneWidget::pick` unprojects a click to a world
segment and intersects the scene's own triangles/points;
`ScalarField3D::pick_cut_plane` / `value_at` pick the cut plane and sample the
volume; `ScalarFieldView::pick` unifies both into a `FieldPick` (world position
+ field value). The composed `SceneWindow` shows a `ScenePositionInfo` readout
(port of `PositionInfoWidget`: X/Y/Z/Data) fed by the cursor pick each frame.
- **Documented simplifications**: colormaps are applied on the CPU at
geometry-build time (not via a GPU colormap texture); silx's per-item
`_pickFull` richer payloads (data-index/bin resolution, image pixel indices —
beyond world position + sampled value) and its generic `plot3d._model`
scene-graph tree editor are deferred, noted in the roadmap rather than stubbed.
### Added — `siplot` 2D plotting completions (`silx.gui.plot` parity)
The remaining `silx.gui.plot` gaps were closed, finishing the parity port begun
in 0.1.0 / 0.2.0. Tracked row by row in `doc/parity-roadmap.md`.
- **`ImageStack` lazy/threaded loading**: a second mode beside the in-memory
`set_frames` — `set_sources` + a pluggable `set_loader` (`FrameLoader` trait,
silx `setUrls`/`setUrlLoaderClass`) load each slot on a background thread, with
a configurable prefetch radius (`set_n_prefetch`, silx `_preFetch`/`N_PRELOAD`)
that preloads neighbours as you browse. A concrete `Hdf5FrameLoader` reads 2D
datasets and 3D-stack slices on demand, and the frame table shows each source
URL with a per-row remove (silx `UrlList`/`removeUrl`).
- **`CompareImages` SIFT auto-alignment**: the `AUTO` mode registers image B onto
image A via SIFT keypoints + affine least squares (`core::sift_align` on the
pure-Rust `lowe-sift` crate, mirroring silx `__createSiftData`→`LinearAlign`),
with `transformation()` exposing the decomposed affine (silx `getTransformation`),
an `Align:` status-bar summary, and a toggleable matched-keypoint overlay.
- **`PrintPreview` page editor**: a print-preview window with page layout/scale
controls (silx `PrintPreviewToolButton`/`PrintPreviewDialog`).
- **Mask file save/load — all five silx formats**: npy, EDF (fabio-style), TIFF,
HDF5 (with a "Select a 2D dataset" picker, faithful to silx's `"a"` append
mode), and fit2d `.msk` (byte-verified against fabio), behind native Load/Save
toolbar actions.
- **Per-pixel image alpha map** (silx `ImageData.setAlphaData`), preserved across
image re-uploads.
- **Round line joins + caps** for thick polylines (silx line-join rendering).
- Completed interactive 2D tooling: the ruler measurement tool, `PositionInfo`
live cursor snapping, the `AlphaSlider` active-image binding, the
`ComplexImageView` amplitude-range dialog, the `StackView` 3D-profile toolbar +
2D stacked-profile window, the `CompareImages` draggable split separator, the
`ScatterView` line-/scatter-profile tools, and the ROI manager table widget
with Arc three-point/polar modes, Band unbounded mode, an interaction-mode
submenu, save/load dialogs, the `sigRoiAboutToBeRemoved` signal, and concave
polygon fill via ear-clipping triangulation.
- **Colormap registry**: `register_colormap` for named LUTs and colormap-state
serialization round-trips.
### Changed — `siplot`
- New optional-feature-free dependencies scoped to the mask/alignment work:
`tiff` and the pure-Rust `rust-hdf5` (mask TIFF/HDF5 save/load) and `lowe-sift`
(CompareImages AUTO alignment). All are plain build-everywhere crates — no
native `libhdf5` and no Python/OpenCV.
### Note on parity scope
The `silx.gui.plot` parity queue is exhausted. The remaining non-ported items
are documented accepted residuals, not omissions: custom marker fonts (egui
`FontId` cannot express QFont weight/italic without bundled font assets), async
GPU stats/histogram (CPU equivalents are complete), the mid-gesture
`sigInteractiveRoiCreated` signal (immediate-mode emits `DrawingProgress`
instead), runtime matplotlib-dynamic colormap loading (needs a Python
dependency), a native print dialog/printer submission (OS-native; the preview is
ported), and an OpenGL backend selector (N/A — siplot is wgpu-only).
## [0.2.0] - 2026-06-13
The headline of this release is two new crates — **sidm** and **adl2sidm** —
alongside a large expansion of siplot. siplot 0.1.0 was the plotting library
alone; 0.2.0 turns the workspace into a full EPICS display stack and a MEDM
screen converter on top of it.
### Added — `sidm` 0.2.0 (new crate)
A PyDM-style EPICS display layer ported from `pydm` onto siplot + epics-rs.
- A headless data **`Engine`** owning a tokio runtime, with channel addresses
over `ca://` (Channel Access), `pva://` (pvAccess), `calc://` (a pure-Rust
derived-channel expression evaluator), and the IOC-free `loc://` / `fake://`
schemes. The EPICS backends are feature-gated (`ca`, `pva`, `calc`, all
default-on); `--no-default-features` gives the dependency-light core.
- The PyDM widget set: `SidmLabel`, `SidmLineEdit`, `SidmEnumComboBox`,
`SidmEnumButton`, `SidmPushButton`, `SidmSlider`, `SidmSpinbox`,
`SidmByteIndicator`, `SidmScaleIndicator`, `SidmDrawing`, `SidmImage`,
`SidmImageView`, `SidmFrame`, and the siplot-backed plots `SidmTimePlot`,
`SidmWaveformPlot`, `SidmScatterPlot`.
- MEDM/PyDM display fidelity: display-format and precision handling, alarm
severity colouring with selectable MEDM/PyDM palettes, a disconnect-only
border mode, justified MEDM-cell geometry with vertical/horizontal centering,
and a single-owner no-local-echo write model (values re-sync from the monitor).
- MEDM Btn2 **middle-click PV-name copy** (clipboard + X11 PRIMARY on Linux),
matching MEDM/PyDM operator workflows.
- Channel writes go out as plain `CA_PROTO_WRITE` (never `WRITE_NOTIFY`), so a
busy record can never stall a writer; discarded/failed writes log through the
`log` facade.
### Added — `adl2sidm` 0.2.0 (new crate)
A converter mirroring `adl2pydm`, but emitting **compile-checked Rust source**
instead of Qt `.ui` XML.
- Parses a MEDM `.adl` screen into a widget IR and emits a self-contained SiDM
`Screen` module; the generated code is compile-gated against the real `sidm`
API (a fidelity check `adl2pydm` cannot do against Qt).
- Every MEDM widget maps to a real SiDM widget, including arc/polygon/polyline
shapes, static images, byte/bar/indicator/meter monitors, and the plots.
- Structural z-order: decoration behind, controls on top, pinned by `egui::Order`
and emitted one placement per child layer so a composite reproduces MEDM
file order on every layer while staying a transparent group.
- Faithful MEDM rendering: per-widget height-derived fonts, `clr`/`bclr` colours
reaching widget faces, dynamic-attribute `clr` alarm/discrete colour rules,
`calc://`-gated visibility rules, uniform `$(macro)` expansion in every string,
and a responsive (window-filling) layout mode that is the default
(`--absolute` opts back into fixed MEDM pixels).
- **Recursive related-display conversion**: a related-display button opens the
converted child screen in an egui viewport, with runtime macro tables built at
click time (MEDM `relatedDisplayCreateNewDisplay` semantics).
- A `clap` CLI (`--protocol` / `--macro` / `--out` / `--absolute` /
`--use-scatterplot`) and an installable `adl2sidm` binary.
### Added — `siplot` 0.2.0
- **Interactive histogram colorbar** with draggable vmin/vmax handles, an
auto-range context menu, and an in-chrome gutter rendering for `ImageView` /
`Plot2D`.
- **Multi-axis Y** (`YAxis::Extra(n)`, N stacked Y axes) with an ergonomic
`Plot1D` multi-axis API.
- **Time-aware X axis**: DST-correct named-zone offsets, a wall-clock tick mode,
and an X-axis time offset so relative vertices show absolute ticks.
- **FitWidget**: multi-peak Gaussian fitting with auto peak-search, a background-
model selector, an editable initial-parameter input, and the full leastsq
constraint set (FREE/POSITIVE/FIXED/QUOTED/FACTOR/DELTA/SUM/IGNORED).
- **Composite views**: StackView (3D-profile data layer, per-axis calibration,
per-frame block aggregation), ScatterView (line-profile extraction), and
CompareImages (RGB composite modes, origin/center/stretch alignment, a
coordinate/value status bar).
- **Export**: SaveAction gains JPEG, PDF, and EPS raster export (all with
hand-written encoders, no new dependencies) and a printer-selection Print
dialog.
- **Save/load**: mask EDF codec and ROI text serialization.
- Toolbar/interaction additions: RulerToolButton + distance core, a
zoom-enabled-axes menu with box-zoom constraint, pan-with-arrow-keys toggle,
reusable Profile/Symbol tool buttons, and a LimitsToolBar.
- Scatter IRREGULAR_GRID vertex-indexed mesh with cell picking, plot-wide curve
style cycling, and live StatsWidget binding across all plot items.
### Changed
- siplot is now the root of a three-crate workspace; `sidm` reaches egui/wgpu
through `siplot::egui` to keep a single egui/wgpu in the tree.
