The procedure returns a list containing a count and an array of path IDs.
I would recommend converting this to a list using the R5RS function 'vector->list'. Mind that the "vector" in 'vector->list' is what Scheme chooses to call an array; it is completely unrelated to the GIMP concept of vectors/paths. To avoid confusion, I use the older "path" terminology for my user-defined functions and variables.
(let ((paths (vector->list
(cadr (gimp-vectors-import-from-file image
filename
FALSE
scale-to-imagesize )))))
; we now have a list of 'paths' that have been imported.
; To select from the first path in the list, use the 'car' function
(gimp-vectors-to-selection (car paths) 2 TRUE FALSE 0 0)
)
If more than one path has been imported, you could loop through the list of path IDs, adding each selection.
