Detailed Description

Auto-tiling algorithm defaults.

Min/max constraints used by the tiling algorithms themselves. These are algorithm-layer concerns — independent of any user-facing default values the application config layer may surface.

Function Documentation

isNumericMetaType()

constexpr bool PhosphorTiles::AutotileDefaults::isNumericMetaType ( int  typeId )

constexpr

Returns true if typeId is a numeric QMetaType (Double, Float, Int, UInt, LongLong, ULongLong).

Used for fuzzy-comparing QVariant values after JSON round-trip type drift.

Variable Documentation

DefaultAlgorithmId

constexpr QLatin1String PhosphorTiles::AutotileDefaults::DefaultAlgorithmId {"bsp"}

inlineconstexpr

Default tiling algorithm.

DefaultInnerGap

constexpr int PhosphorTiles::AutotileDefaults::DefaultInnerGap = 8

constexpr

DefaultMasterCount

constexpr int PhosphorTiles::AutotileDefaults::DefaultMasterCount = 1

constexpr

Single master window.

DefaultMaxWindows

constexpr int PhosphorTiles::AutotileDefaults::DefaultMaxWindows = 5

constexpr

Maximum tiled windows before overflow.

DefaultOuterGap

constexpr int PhosphorTiles::AutotileDefaults::DefaultOuterGap = 8

constexpr

DefaultSplitRatio

constexpr qreal PhosphorTiles::AutotileDefaults::DefaultSplitRatio = 0.5

constexpr

50/50 split when nothing else specified

DefaultSplitRatioStep

constexpr qreal PhosphorTiles::AutotileDefaults::DefaultSplitRatioStep = 0.05

constexpr

GapEdgeThresholdPx

constexpr int PhosphorTiles::AutotileDefaults::GapEdgeThresholdPx = 5

constexpr

MaxGap

constexpr int PhosphorTiles::AutotileDefaults::MaxGap = 50

constexpr

MaxInsertPosition

constexpr int PhosphorTiles::AutotileDefaults::MaxInsertPosition = 2

constexpr

MaxMasterCount

constexpr int PhosphorTiles::AutotileDefaults::MaxMasterCount = 5

constexpr

MaxMaxWindows

constexpr int PhosphorTiles::AutotileDefaults::MaxMaxWindows = 12

constexpr

MaxMetadataWindows

constexpr int PhosphorTiles::AutotileDefaults::MaxMetadataWindows = 100

constexpr

MaxRuntimeTreeDepth

constexpr int PhosphorTiles::AutotileDefaults::MaxRuntimeTreeDepth = 50

constexpr

Maximum recursion depth for split tree operations.

MaxSplitRatio

constexpr qreal PhosphorTiles::AutotileDefaults::MaxSplitRatio = 0.9

constexpr

MaxSplitRatioStep

constexpr qreal PhosphorTiles::AutotileDefaults::MaxSplitRatioStep = 0.25

constexpr

MaxTreeNodesForJs

constexpr int PhosphorTiles::AutotileDefaults::MaxTreeNodesForJs = MaxZones * 2

constexpr

Cap on total node count when converting a SplitTree to a QJSValue object.

Each tiled window occupies one leaf plus at most one internal node, so MaxZones*2 is a safe ceiling that lets the widest valid tree through without truncation.

MaxZones

constexpr int PhosphorTiles::AutotileDefaults::MaxZones = 256

constexpr

MinGap

constexpr int PhosphorTiles::AutotileDefaults::MinGap = 0

constexpr

MinInsertPosition

constexpr int PhosphorTiles::AutotileDefaults::MinInsertPosition = 0

constexpr

MinMasterCount

constexpr int PhosphorTiles::AutotileDefaults::MinMasterCount = 1

constexpr

MinMaxWindows

constexpr int PhosphorTiles::AutotileDefaults::MinMaxWindows = 1

constexpr

MinMetadataWindows

constexpr int PhosphorTiles::AutotileDefaults::MinMetadataWindows = 1

constexpr

MinRectSizePx

constexpr int PhosphorTiles::AutotileDefaults::MinRectSizePx = 50

constexpr

MinSplitRatio

constexpr qreal PhosphorTiles::AutotileDefaults::MinSplitRatio = 0.1

constexpr

MinSplitRatioStep

constexpr qreal PhosphorTiles::AutotileDefaults::MinSplitRatioStep = 0.01

constexpr

ScriptWatchdogTimeoutMs

constexpr int PhosphorTiles::AutotileDefaults::ScriptWatchdogTimeoutMs = 100

constexpr

Watchdog deadline for a single JS evaluation guarded by ScriptedAlgorithm::guardedCall().

Generous enough for ARM / slow systems where JS startup and first-call JIT warmup can take tens of milliseconds. Exposed here so operators tuning for their target hardware don't need to recompile the scriptedalgorithm TU.

SplitRatioHysteresis

constexpr qreal PhosphorTiles::AutotileDefaults::SplitRatioHysteresis = 0.05

constexpr

Band within which algorithm-switch ratio reset is suppressed.

UnlimitedMaxWindowsSentinel

constexpr int PhosphorTiles::AutotileDefaults::UnlimitedMaxWindowsSentinel = std::numeric_limits<int>::max() / 2

constexpr
