+.ggb | addition operator for ggb object to support ggplot-like syntax
+.ggbrain_images | summary S3 method for ggbrain_images objects addition operator for combining ggbrain_images objects
annotate_coordinates | Adds the coordinate labels to each panel based on the location of the slice along the slicing axis (e.g., z = 15)
annotate_slice | Adds custom annotations to a single panel on the ggbrain plot
count_neighbors | This function counts the number of neighboring/touching pixels in a 2D binary image
define | Adds contrast definitions to the ggbrain plot
fill_from_edge | This function finds holes by flood filling TRUE into a 2D binary image, starting from the edge
find_threads | This function finds 'threads' hanging off of the edges of blobs in an image, allowing the user to trim them
flood_fill | This function flood fills a binary image with TRUE for any value of FALSE
geom_brain | Adds a raster layer to the ggbrain plot, displaying pixels from the specified layer definition
geom_outline | Adds an outline layer to the ggbrain plot, displaying outlines from the non-missing pixels in the specified layer definition
geom_region_label | Variant of geom_label used for plotting region labels on slices
geom_region_label_repel | Variant of geom_label_repel used for plotting region labels on slices with separation from other labels
geom_region_text | Variant of geom_text used for plotting region labels on slices
geom_region_text_repel | Variant of geom_text_repel used for plotting region labels on slices with separation from other labels
