Creating interactive GIMP brushes

[eepjr24]

Sorry, but it just won't work in Gimp given the way brushes work. The closest I've come with a double track brush is to make it bow-tie shaped with faded edges to allow for the angles without overlapping. You don;t need to make a GIH, just a single brush and enable brush dynamics, pickling "Track Direction", which will do the rotating for you. But it will never form clean cart tracks/lines.

If you are comfortable working with paths, it is better to to this making three strokes along the same path - one wide soft stroke in the lighter colour to make the outline, then one harder dark stroke to make the main track, then a smaller hard stroke in the light colour again to "clear" the space between the tracks. Here is an example done that way:

I built the screen shot with selections and stroking. =) I am trying to make it so I don't have to do that. You can skip one step in the process if you use a 4px hard brush and just shrink the path or selection by 8px before you stroke it. I suppose I can just make it a plugin that takes a selection and puts the wagon tracks on it. Just trying to make things automated and reduce clicks to whatever extent is possible.
