v0.1.0-alpha01

Tilo Compose 0.1.0-alpha01

The first public alpha of Tilo Compose: a Compose-first Kotlin Multiplatform
toolkit for maps and GIS applications on Android and iOS.

Highlights

• Declarative TiloMap API with camera state, layer DSL, animated pan and zoom,
  double-tap zoom, fling, and fitBounds.
• Raster maps from WMS, XYZ/TMS, OpenStreetMap, and application-owned tile
  stores, with observable loading state, retry, attribution, and concurrent tile
  fetching.
• Projection-aware rendering with WGS 84, Web Mercator, and S-JTSK / Krovak
  helpers. Android transformations use Proj4J; iOS includes PROJ 9.8.1.
• Vector points, lines, polygons, multi-geometries, holes, labels, styling, and
  immediate or cached-bitmap rendering.
• Label priorities, line rotation, selected-label styles, bitmap caching, and
  global collision handling.
• Feature selection with multiple hits, selected styles, and application-owned
  Compose callouts.
• Optional drawing module for points, lines, and polygons, including undo,
  redo, clear, custom controls, and application-owned save callbacks.
• Optional spatial index for efficient viewport queries.
• Default scale bar, attribution overlay, zoom controls, and an opt-in
  performance debug overlay.
• Android and iOS sample applications, including live ČÚZK orthophoto rendered
  directly in EPSG:5514.

kotlin {
    sourceSets {
        commonMain.dependencies {
            implementation("eu.tilomaps:tilo-compose:0.1.0-alpha01")

            // Optional interactive drawing support

Alpha status

This is an early public release. Public APIs may change between alpha versions
as usage feedback is incorporated before 1.0.

Known limitations include:

• no map rotation or bearing;
• no dedicated MBTiles layer yet;
• no first-class MVT/vector-tile decoder;
• no layer grouping or layer-level opacity;
• accessibility and offline-state support are still incomplete.
