Selection of a path component

Herbie · **Joined:** Aug 22, 2017 **Posts:** 72

An existing vector path consists of more than one component. I would now like to make a selection of, for example, the first and third components.

With the method

Code: Select all

pdb.gimp_image_select_item(image, CHANNEL_OP_REPLACE, vector_id)

a selection can unfortunately only be made from the entire path.

Can I convert a stroke ID into an item ID?

No, you have to make a new path with the strokes (the "components") you want and then make a selection on the result path. Not that hard. For instance the code to split a path into its constituents (one path per stroke):

Code: Select all

    for stroke in path.strokes:
        strokePath=gimp.Vectors(image,'%s [%d]' % (path.name,stroke.ID))
        points,closed=stroke.points
        gimp.VectorsBezierStroke(strokePath,points,closed)
        pdb.gimp_image_insert_vectors(image, strokePath, None,-1)  
        strokePath.visible=True
