How would I fill blank areas within apple automaticaly , either with expanding existing vectors to fit neighbours or filling blancks with new vectors ?
To get rid of the white stroke do as follows;
Select all objects; CTRL + A
Ungroup; SHIFT + CTRL + G (do this several time until there are no more groups. Check the status line at the bottom of the main Inkscape window)
Duplicate all objects; CTRL + D
Change all selected objects to paths; SHIFT + CTRL + C
