Quoting Sebastian Breuers <sebbreuers@xxxxxx>:
i wondered if there is a possibility to check, if a point is in a given
selection by using an internal gimp function.
If it's not, could someone give me a hint, how to achieve this in creating an
own function?
I don't use Python-fu but the following Script-fu function should be
easily ported (or perhaps you can find a better way):
(define (point-in-selection image x y)
(let* (
(saved (car (gimp-selection-save image)))
(return-value)
)
(gimp-rect-select image x y 1 1 CHANNEL-OP-INTERSECT 0 0)
(set! return-value (car (gimp-selection-is-empty image)))
(gimp-selection-load saved)
(if (= return-value 0)
1
0
)
)
)
Note that the selection does not include the points at the rightmost
and bottommost edges. For example, if the selection is from (0,0) to
(10,10) then the point (10,10) is *not* "in" the selection but (9,9)
is. You may need to adjust things to account for this.
