[Ipe-discuss] Creating arcs in lua ipelet

[cristo]

Hello,

I am trying to create an ipe.Arc in a lua ipelet using the following code:

arc_shape = {}

table.insert(arc_shape, { type="curve", closed=false })
table.insert(arc_shape, { type="arc", arc=ipe.Arc(m, points[j], points[i])
})
table.insert(arcs, ipe.Path(model.attributes, arc_shape))

where the points table is obtained in the following way:

for i, obj, sel, layer in p:objects()
do
    if sel
    then
        if obj:type() == "reference" and obj:symbol():sub(1,5) == "mark/"
        then
            table.insert(points, obj:matrix() * obj:position())
        end
    end
end

When I run the ipelet, I get this error

/home/cristo/.ipe/ipelets/rch.lua:340: element 2 has invalid type

stack traceback:

[C]: in function 'Path'

/home/cristo/.ipe/ipelets/rch.lua:340: in function 'maximal_arcs'


The line mentioned in the error is in which ipe.Path is created. Does anyone
can see where am I wrong?


Thanks in advance
