Enum TileTextureFormat

Namespace

LansMap.Core.Tiles.Sources

The GPU residency format a TileSource asks its tiles to be uploaded as.

public enum TileTextureFormat

Fields

RGB565 = 1

16-bit RGB, no alpha, 2 bytes/pixel (half of RGBA32). Opt-in: see TextureFormat for the quantization/banding trade-off and the per-device capability fallback.

RGBA32 = 0

Uncompressed 32-bit RGBA. The default; every existing TileSource gets this unless it names RGB565 explicitly. Guaranteed supported on every device/graphics API this project targets.

Remarks

Closed by design: a registry or third-party extension point comes only after one non-default format has cleared the platform matrix end to end, not before. Do not add one here.

Both members are wired end to end: TileBatchRenderer resolves the requested format against device capability (SystemInfo.IsFormatSupported) before allocating its array and staging texture, falling back to RGBA32 loudly on a device/API that cannot sample RGB565; TileStreamer and TileDecodeWorker honour the array's resolved format on the upload path, including packing to RGB565 on the decode worker thread rather than the main thread. See TextureFormat for what RGB565 costs.
