Prints a structured summary of a GraphSpace object,
including graph topology, optional feature data, and spatial boundaries
for nodes and, when present, the background image.
Node boundaries are always drawn from @graph (original pixel
coordinates, never modified). Image boundaries reflect @canvas
after normalization with image.space = TRUE, and @image
otherwise. When normalized, both boundary lines show the source range
and [0,1] target to make the transformation explicit.
Usage
# S4 method for class 'GraphSpace'
summary(object, ...)Value
Invisibly returns object, allowing the call to be used inside
a pipeline without side effects beyond the printed output.
