annotatR S3 classes

annotatR represents annotations with a small set of S3 classes. This page collects them so they can be cross-referenced from the documentation.

annot_image

A backend-agnostic image handle holding metadata and a lazy tile accessor. Created by at_read_image() or at_example_image().

annot_roi

A single region of interest: an sf geometry in image pixel coordinates at a declared pyramid level. Created by the at_roi_*() constructors.

annot_layer

A named collection of ROIs sharing a label vocabulary and a visual style. Created by at_layer().

annot_project

An image plus a named set of layers and provenance. Created by at_project().

annot_session

A resumable batch-annotation session over a queue of images. Created by at_session().

annot_mask

A rasterised mask: a labelled or binary integer matrix with a legend. Created by at_mask().

annot_style

A layer style specification. Created by at_style().

annot_summary

A compact per-label project summary. Created by at_summary().
