Initial release. TIFF/COG metadata scanning and tile decoding from R via Rust, without GDAL or Python.
tiff_refs() scans TIFF/COG files and returns a data.frame of tile
byte-range references (path, IFD, tile col/row, offset, length, dimensions,
dtype, compression, CRS EPSG). Accepts S3, GCS, Azure, HTTP/HTTPS, and
local file paths.
tiff_tile() fetches and decodes a single tile from a TIFF/COG.
tiff_tiles() fetches multiple tiles from the same file in a single call.
tile_to_array() converts a tile result to an R matrix (single band) or
3D array (multi-band).
refs_to_kerchunk() converts a refs data.frame to Kerchunk V1 JSON.
Built on async-tiff 0.2 (Development Seed) and object_store 0.13 (Apache arrow-rs) via extendr 0.7. Async I/O via tokio; all cloud credential resolution follows object_store conventions.
