In trying to add a 1cm seam allowance outside a pattern drawn with Inkscape 4.8, : 1. the Outset is shaped properly, has the correct width, but it is positioned *over* the path, half in and half out, instead of being placed 100% outside of the path. Is this the intended behavior? 2. The outset doesn't inherit the properties of the path selected, it has a 'fill' by default. I have to select the edit object icon, and set fill to 'x' and stroke to solid. Is there a way to cause the 'Outset' path to inherit the selected path's properties? 3. When I select 'Inset' on the same path,just as a test to see what happens, I get a very small tight grouping of points that have no apparent relationship to my pattern shape. I don't really need 'Inset' at the moment, just thought I'd mention it.
I'm new to Inkscape, so perhaps there is something that I am missing.
Any suggestions?
Thanks, Susan
I'm looking for ways to access Inkscape UI functionality from within an extension:
1. Is there a way to apply the Outset/Inset functionality from within an extension? I have found some documentation regarding the Inkscape verb SP_VERB_SELECTION_OFFSET, but I'm not seeing a way to access this, or access it from a wrapper, from a Python script.
2. Is there a way to select a node and change it's sodipodi nodetype value to 'symmetrical' or 'smooth'? Again, I would like to be able to skip using the desktop icon. Perhaps it's possible to add nodetype in the attributes when the node is created, but I've experimented a bit and haven't seen this attribute show up in the XML until I've manually changed the node to 'symmetrical' using the UI.
And thanks very much to ~suv for the assistance in helping me understand the Outset/Inset functions, and the 'change to path' functions for my previous questions.

I don't think it's possible from an extension (unless lib2geom's python wrapper allows for this functionality), but you might be able to do it from the command line (so you could call inkscape from a script and do this). If you execute: inkscape --verb-list you get a list of all the verbs inkscape supports, you may want to output this to a file (or pipe it through more or less, or use grep): inkscape --verb-list > verblist.txt Now you can peruse the list of supported verbs at your leisure.
In your case you probably want to do something like this: inkscape --select=MyObjectID --verb=SelectionOffset --verb=FileSave --verb=FileQuit design.svg Note that this should all be on ONE line.
More command line options can be found using inkscape --help

The problem is that this is mostly an Inkscape thing, so the underlying path could be the same but the behaviour in Inkscape's UI would be different. I'm not quite sure what Inkscape would do if an extension modified the path so that it claimed certain nodes were smooth without actually modifying the path, barring that I think the only thing you could do in an extension (or in a wrapper) is basically doing the math yourself (it's not extraordinarily hard, if you need help just ask).
You may also want to have a look at spiro's (these are implemented a bit differently, using live path effects and might be well suited to your purpose).
