Class AtlasGroupBuilder

Namespace: KernSmith.Atlas

Assembly: KernSmith.dll

Packs rects from multiple independent glyph sources into a single shared IAtlasPacker pass, then splits the resulting placements back out per source so each can feed its own BmFontModel build.

Remarks

Id/Id is usually a Unicode codepoint, so two sources (e.g. a primary font and a shadow variant with the same character set) will typically collide on id. This builder mangles each source's ids into a composite id before calling Pack(IReadOnlyList<GlyphRect>, int, int), then restores the original id when splitting results back out. The mangling is entirely internal — callers only ever see original ids.

Methods

Pack(IAtlasPacker, IReadOnlyList<GroupSource>, int, int)

Packs all sources' rects into one shared atlas, then splits the placements back out per source, keyed by each source's own original id.

public static (PackResult Shared, IReadOnlyDictionary<string, IReadOnlyDictionary<int, GlyphPlacement>> PlacementsByTag) Pack(IAtlasPacker packer, IReadOnlyList<AtlasGroupBuilder.GroupSource> sources, int maxWidth, int maxHeight)

Parameters

packer IAtlasPacker: The packer to use for the single combined pack call.
sources IReadOnlyList<AtlasGroupBuilder.GroupSource>: The tagged glyph-rect sources to pack together.
maxWidth int: Max page width in pixels.
maxHeight int: Max page height in pixels.
