I have requested the namespace Tk::Canvas::Draw, which I agree seems like the best choice.
zentara: Certainly bezier lines would be a good addition; I'll plan to include them soon. As far as saving data for later, you could do that very easily with use Storable, so I didn't explicitly provide the capability. And when you say:
"...an eraser function for the lines"
You do realize, don't you, that the IDs of all lines/shapes drawn are passed to the results subroutine? Thus, deleting those shapes is as easy as:
my $o_obj = new Tk::Draw($c1, \&done_drawing, $h_opts); sub done_drawing { my ($o_obj, $a_points, $a_ids) = @_; map { $o_obj->canvas->delete($_) } @a_ids; }
But perhaps I'll simplify that further, and provide a delete_shapes method to the object.
hangon: Thanks for confirming the name (Tk::Canvas::Draw) that I was considering as an alternative for the module.
As for your two specific suggestions, plugins and "snapping points to a shape", if you wouldn't mind providing me with more details, or even some example code, I'd be more than happy to consider both of them.
