Hi,
I have a situation where I need to draw some polylines with vertices. I thought the Path tool would be ideal for drawing the lines, and so it was. But I also need there to be a dot, or an X, or some such marker at each anchor point. So, is there a way to automatically place a glyph or something at each anchor location? Or, failing that, is there a way to make a mark at each desired anchor point location, then use those to create a path?

Thanks

That works beautifully, thank you! I modified it slightly so it loops through all the paths in the layer, and it works just as required.

Now I just need to figure out how to stroke the paths.

Hi, the the way to do this is to use Python to iterate over the Path coordinates and
making a paintbrush stroke mark at each of them.

Set the paintbrush for your desired "X" mark, yur image in the last (right most) tab in GIMP, and your desired layer as the top layer - them open the Python console with filters->python console And paste this in there:

img = gimp.image_list()[0]

for stroke in img.vectors[0].strokes: for i in range (0, len(stroke.points[0]), 6): coords = stroke.points[0][i:i + 2] pdb.gimp_paintbrush_default(img.layers[0], 2, coords)

And you are set. The "[0]" on the first line is the index of the rightmost image tab, the "[0]" on the "for i" line is for the topmost path, and the "[0]" on the last line for the topmost layer. CHange your idnexes according to the desired targets.
