- Add a global LUT library: user-configurable directories (new
Preferences > LUT tab) scanned recursively for .cube/.3dl files; LUT
node file pickers offer the library dirs as sidebar shortcuts via a
'lut_library' input property handled by the param view bridge
- OCIOLutNode no longer fails silently: missing files, unsupported
extensions and OCIO load errors are recorded in last_error() and
surfaced in the status bar (input still passes through for rendering
safety)
- ColorDialog: re-enable the display -> reference conversion using
ColorProcessor::kInverse with a validity guard, and re-enable the
Display tab in ColorValuesWidget; covered by a round-trip regression
test proving the old OCIO inverse crash no longer occurs
- OCIOGradingTransformLinearNode: enforce the OCIO clampWhite >
clampBlack invariant per frame in Value() so keyframed/connected
values cannot produce invalid grading transforms, and constrain the
white clamp UI minimum whenever the black clamp is static
- Regression tests for LUT extension checks, direction switching, node
error reporting, LUT library scanning, display inverse round-trip and
clamp enforcement
In NodeParamView::SetSelectedNodes, after locating the target node item,
expand and raise its containing NodeParamViewContext dock widget so the
active tab/folded section switches to the one that actually holds the node.
ColorCorrectOFX and similar plugins declare per-channel controls
(Gamma, Contrast, Saturation, Gain, Offset) as kOfxParamTypeRGBA.
Olive previously mapped every RGBA param to NodeValue::kColor and
rendered it as a ColorButton, which is semantically wrong for
adjustment sliders.
This commit adds heuristic semantic detection to distinguish
"true color" inputs (color pickers) from "per-channel scalar"
inputs (float sliders):
- label/hint/name keywords ("gamma", "contrast", "gain", ...)
- display range outside [0, 1]
- uniform default values across all channels
The detected semantic ("color" or "scalar") is stored as the
node input property "color_semantic". The display range and hint
are also persisted as "min" / "max" / "tooltip".
NodeParamViewWidgetBridge now branches on "color_semantic":
- "scalar" → 4× FloatSlider (reuses existing ProcessSlider /
keyframe-track logic, since kColor already splits into 4 tracks)
- otherwise → ColorButton (unchanged)
All 4 test suites pass.
Code is much better. Less hacky queuing, implements cooldowns to improve navigation, and introduces a framework so that subclasses can make use of catchup/cooldown code too with any scrollbar they want
