HeatmapPaint¶

Namespace: ThinkGeo.Core.Styling

The resolved paint of one heatmap style layer at one zoom.

public struct HeatmapPaint

Inheritance object → ValueType → HeatmapPaint

Remarks:

Radius and weight may be data-driven per the style spec, so they resolve through a feature-aware function like extrusion height does; intensity and opacity are zoom-only. The color ramp is not here: it never varies with zoom or feature, so it bakes once at compile time.

Properties¶

Radius¶

Gets the kernel radius in pixels (heatmap-radius, default 30).

public float Radius { get; }

Property Value¶

float

Intensity¶

Gets the global density multiplier (heatmap-intensity, default 1).

public float Intensity { get; }

Property Value¶

float

Opacity¶

Gets the layer opacity (heatmap-opacity, default 1).

public float Opacity { get; }

Property Value¶

float

Weight¶

Gets one point's density contribution (heatmap-weight, default 1).

public float Weight { get; }

Property Value¶

float

Constructors¶

HeatmapPaint(float, float, float, float)¶

Initializes a new instance of the HeatmapPaint struct.

HeatmapPaint(float radius, float intensity, float opacity, float weight)

Parameters¶

radius float
Kernel radius in pixels.

intensity float
Global multiplier on the accumulated density.

opacity float
Layer opacity, 0 to 1.

weight float
One point's contribution to the density.
