Read ROIs from a CSV with WKT geometry

Read ROIs from a CSV with WKT geometry

Usage

at_read_rois_csv(
  path,
  layer_name = "csv",
  call = rlang::caller_env(),
  coordinate_level = NULL,
  legacy_levels = c("error", "recorded")
)

Arguments

path

Path to a CSV with at least label and geometry (WKT) columns. Other columns (roi_id, level, author, source, created, modified) are used when present. Every column is read as text, so labels and ids such as "T", "007" or "NA" are kept verbatim. level is the pyramid level of the WKT coordinates.

layer_name

Layer name for the imported ROIs. Default "csv".

call

The calling environment, for error reporting.

coordinate_level

Optional integer overriding every recorded level without scaling coordinates. Use only when the actual coordinate level is known, for example 0L for legacy hyperannotatR exports that wrote level-0 coordinates beside a nonzero source level. NULL (default) uses the schema and legacy_levels policy. Coordinates are never automatically repaired.

legacy_levels

How to interpret files without the coordinate_schema marker: "error" (default) rejects ambiguous nonzero recorded levels; "recorded" explicitly trusts those levels. Level-0 files remain unambiguous.

Value

An annot_layer.
