Re: [Inkscape-devel] "Flatten" vectors, progress, help needed

Hi, I implemented most of the parts, you can find the code here: https://code.launchpad.net/~inkscape+alexander/inkscape/flatten New features: Path->All Objects to Path This recursively convertes strokes to paths. If the object has a fill and a stroke it is duplicated for one copy the stroke is converted to a path, for the other the stroke ist set to none. Therefore the visual appearance doesn't (shouldn't) change. Object->Clip->Intersect This recursively replaces clipped paths by the path intersected with the clip path. Path->Remove Overlap This doesn't work and I don't understand why. It's implemented in splivarot.cpp, line 1740 The basic idea is very simple: 1. Get all selected shapes, even indirectly selected ones in groups etc. 2. Sort them so the topmost shape is the first in the list 3. Get a copy of the topmost shape, total_union = copy(topmost_object) 4. Get the next object in the list "current_object", make a copy "duplicate_object" 5. Make a copy of total_union, name it total_union_duplicate 6. Subtract "total_union_duplicate " from "current_object" using "sp_selected_path_boolop", with operation "bool_op_diff" This doesn't work for me, the method never does anything (line 1816) 7. Add "duplicate_object" to "total_union" using "sp_selected_path_boolop" with operation "bool_op_union" This also doesn't work, I expect to get exactly 1 object, instead I get 2 (line 1834) 8. If list not empty goto 4 I'm out of ideas why the boolean operation doesn't work for my objects, it always works perfectly for me when I do it by hand. Any ideas / comments? Alexander
