For each region in an atlas, compute the outer border and color the respective vertices in the region-specific color from the annot's colortable.
annot.outline(
annotdata,
surface_mesh,
background = "white",
silent = TRUE,
expand_inwards = 0L
)an annotation, as returned by functions like subject.annot.
brain surface mesh, as returned by functions like subject.surface or read.fs.surface.
color, the background color to assign to the non-border parts of the regions. Defaults to 'white'.
logical, whether to suppress status messages.
integer, additional thickness of the borders. Increases computation time, defaults to 0L.
vector of colors, one color for each mesh vertex
