ofn-gradient-along-path draws a bilinear blend transversally along path strokes, using the current gradient. The gradient is drawn on the active drawable (layer, layer mask, channel....).
The gradient is rendered by stroking the path with decreasing widths, setting the color by sampling the gradient at the corresponding position.
The script can be found in the right-click menu of a path in the Paths list (Decorate>Gradient along path...).
Width: this is the total width in pixels of the stroke (width/2 on each side of the path). Reverse gradient: if false, the gradient is mapped inside-out, if true, it is mapped outside-in. Precision: the precision of the rendering. The Fine renderings make each stroke smaller than
its predecessor by one pixels (.5 pixel each side). The settings are currently : .5, 1, 2, and 5 pixels.
High precision require more stroking passes.Caps style, Join style and Miter limit: these are the stroke line options (see the Edit>Stroke path
documentation for a description). The value of Current means that the script will use whatever value is
currently set in Gimp. the Miter limit setting is used only if the Join style is explicitly set to Miter.
