EncDotNet.S100.Core 0.10.0

EncDotNet.S100.Core

Core abstractions and pipeline framework for working with S-100 based nautical chart data.

Overview

This library provides the foundational types used across the EncDotNet.S100 libraries, including:

• Asset sources — IAssetSource abstraction for reading files from directories (FileSystemAssetSource) or ZIP archives (ZipAssetSource).
• HDF5 abstractions — IHdf5File and IHdf5Group interfaces for reading HDF5 data without binding to a specific HDF5 library.
• HDF5 reader exceptions — S100DatasetSchemaException (a required attribute/group is missing or malformed) and S100DatasetNotSupportedException (the file uses an optional spec feature the reader doesn't yet implement). Both carry product, file, group path, spec reference, and a .WithFile(...) helper used by processor layers to attach the source file name. Hdf5RequiredAttributeExtensions provides ReadRequiredDoubleAttribute / ReadRequiredInt64Attribute / ReadRequiredStringAttribute that translate backend "missing attribute" failures into these typed exceptions.
• Lua scripting abstractions — ILuaEngine and ILuaContext interfaces for running sandboxed Lua portrayal scripts, plus the S100LuaHost host API.
• Coverage pipeline — ICoverageSource, ICoverageRenderer<T>, CoveragePipeline, and supporting types (GridGeoreferencer, CoverageColorScheme, StyledCoverageLayer) for rendering gridded data.
• Vector pipeline — IVectorSource, IVectorPortrayalCatalogue, VectorPipeline, and the DrawingInstruction hierarchy (AreaInstruction, LineInstruction, PointInstruction, TextInstruction) modelled directly on the S-100 Part 9 display list.
• Part9DisplayListReader — parses the Part 9 display-list XML produced by XSLT-based portrayal pipelines (S-124 / S-129 / S-421) into the same unified DrawingInstruction hierarchy that S-101's Lua pipeline emits, so a single renderer can consume both.
• Shared types — IPortrayalCatalogue, ICrsTransform, Viewport, MarinerSettings (S-100 Part 9 §4.2 mariner selections, including the four depth contours and S-101 portrayal toggles such as FourShades, SimplifiedSymbols, RadarOverlay, NationalLanguage), DepthUnit and the DepthFormatting helper for locale-invariant depth conversion / formatting / parsing across metres, feet, fathoms, and combined fathoms-and-feet, BoundingBox, RgbaColor, ColorPalette.
