Class PortrayedDynamicFeatureRenderer

Namespace

EncDotNet.S100.Renderers.Mapsui.DynamicSources

Assembly

EncDotNet.S100.Renderers.Mapsui.dll

Draws dynamic features with a code-defined IDynamicFeaturePortrayal: the portrayal's S-100 Part 9 drawing instructions are lowered by the same scene builder a vector product uses, into self-styled Mapsui features (symbol images and labels).

Remarks

This is the bridge from the portrayal toolkit (EncDotNet.S100.Portrayals.Application) to the dynamic-source overlay host. Symbols take their colours from the portrayal's ApplicationPalette in the palette PaletteAccessor returns when the feature is drawn; the host redraws a source's layer on its next change, so a palette switch shows on the next update.

Like every IDynamicFeatureRenderer it is a pure function of the feature and safe to call from any thread; processed symbols are cached per palette.
