include_tissue_outline.Rd
Ensures section specific processing of observations in relation by identifying the outline of the tissue section (or -sections in case of multiple tissue sections per sample). Additionally, allows to relate observations to the spatial position and extent of image annotations.

A data.frame that contains at least numeric x and y variables.
Logical value. If TRUE
, input data.frame is assumed
to contain polygon coordinates of the expanded image annotation encircling
and sorts them after filtering for those that lie inside the tissue section
in order to plot them via ggplot2::geom_path()
.
Either 'concaveman'' or 'chull'. Defines with which function the tissue outline is computed.
Used to absorb deprecated arguments or functions.
Filtered input data.frame.
