layer boolean operation for each cell

laurent_claurent_c
in Ruby Scripting

I tried the following script, but the region is not taken in account : what did I miss ?

app = RBA::Application.instance
mw = app.main_window

lv = mw.current_view
if lv == nil
  raise "No view selected"
end

cv = lv.active_cellview
if !cv.is_valid?
  raise "No cell or no layout found"
end

begin

  # implement undo
  lv.transaction("Undo Boolean")

  ly = cv.layout

  li1 = ly.layer(1, 0)
  li2 = ly.layer(2, 0)
  li3 = ly.layer(3, 0)
  lout = ly.layer(5, 0)

 ly.each_cell do |cell|
  r1 = RBA::Region(cell.begin_shapes_rec(li1))
  r2 = RBA::Region(cell.begin_shapes_rec(li2))
  r3 = RBA::Region(cell.begin_shapes_rec(li3))

  selection = r1 & r2 - r3
  layout.clear_layer(li1)
  layout.clear_layer(li2)
  layout.clear_layer(li3)

  cell.shapes(lout).insert(selection)
end

ensure

  # implements undo: done.
  lv.update_content
  lv.commit 

end

    Hi Laurent,

    with "begin_shapes_rec", the shapes plus the ones from the subcells are pulled :)

    Also "layout.clear_layer(li)" will clear the shapes from all cells, not just the ones from the cell you're working on. So eventually the result will depend on the order the cells are called (which is undefined in "each_cell".

    I assume you're looking for a pure "cell-local" boolean. In this case you'll need to use per-cell shapes for Region input and need to clear shapes on cell level:

      ly.each_cell do |cell|

    r1 = RBA::Region::new(cell.shapes(li1))
    r2 = RBA::Region::new(cell.shapes(li2))
    r3 = RBA::Region::new(cell.shapes(li3))

    selection = r1 & r2 - r3
    cell.shapes(li1).clear
    cell.shapes(li2).clear
    cell.shapes(li3).clear

    cell.shapes(lout).insert(selection)

  end

    Best regards,

    Matthias
