Shared helpers for rendering arrays and raster objects via terra. These functions are not exported; they encapsulate the common steps needed for plotting SNIC images, seeds, and segments.

Usage

.plot_core(x, plot_args)

.plot_seeds(seeds_xy, x, plot_args, add)

.plot_segments(x, plot_args, add)

Functions

  • .plot_core(x, plot_args) Handles the low-level plotting of either a single band or an RGB composite.

  • .plot_seeds(seeds_xy, x, plot_args, add) Draws seed locations over an existing plot window.

  • .plot_segments(x, plot_args, add) Converts segmentation rasters into polygons and plots them with the supplied style overrides.
