Well, the filling of a region of contiguous pixels from one point, as with the
paint bucket in MacPaint and its descendents (including Photoshop), is more of
a bitmapped concept than a vector graphics concept. One does not really have
access to pixels in SVG (though there are certainly times at which it would be
nice if we did!).
However, suppose we have a pre-existing vector map: a collection of basic
elements like paths and rects and so forth. Then, using JavaScript, one can
attach event handlers to all the elements of that vector map, let the cursor
turn into a paint bucket shaped icon, and allow the click of the mouse on any
particular element be translated into a command that colors that object with
the actively chosen color, gradient or pattern.
So if this is what you mean, then the answer would be with JavaScript as in:
VM = [ list of basic elements ]
for (var i in VM) VM.setAttributeNS(null, "onclick", "paintfill(evt)")
function paintfill(evt){
var O=evt.target
O.setAttributeNS(null, "fill", activeColor)
}
This answer rather presupposes that you're building some kind of drawing app,
of which several proofs of concept have already been demonstrated here and
there.
Hope this makes sense
