(scrollbar, title bar, etc.) from the output if the command is
called from the non-GUI-wrapper environment (where the border area
is part of the rendered output). This was required due to an
unsolved bug in which calling magic to write SVG output from the
wrapper in some pathological case exposed a Tk bug that caused
the Tk grid manager to infinite loop, filling memory without
limit.
Cairo graphics package (magic -d XR), will map the display onto
an SVG surface and save it to a file using the Cairo SVG backend.
Due to the simplicity of the mapping, there are no options to this
plot command; it just creates a file that is a (scalable!)
replica of the layout window.
