Graph::Easy::Layout::Grid
contains routines that calculate cell sizes
on the grid, which is necessary for ASCII, boxart and SVG output.
Used automatically by Graph::Easy.
Exports nothing.
This module injects the following methods into Graph::Easy:
_prepare_layout()
my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();
Returns two hashes ($rows
and $cols
), containing the columns and rows
of the layout with their nec. sizes (in chars) plus the maximum
framebuffer size nec. for this layout. Also returns reference of
a list of all cells to be rendered.
