guilloche

3 motifs. Import them from geomotif.motifs, or build one by name with registry.create("guilloche.band").

guilloche.band

guilloche.band

A woven ribbon along a straight spine: the border of a banknote.

from geomotif import save_svg
from geomotif.motifs import GuillocheBand

motif = GuillocheBand(lines=8)
save_svg(motif.build(), "guilloche.band.svg", width=320, height=320)

geomotif render guilloche.band --out guilloche.band.svg

{
  "geomotif": "1.3.1",
  "motif": "guilloche.band",
  "params": {
    "resolution": null,
    "length": 320.0,
    "height": 76.0,
    "waves": 5.0,
    "counter": 8.0,
    "lines": 8,
    "center": [
      0.0,
      0.0
    ]
  }
}
Parameters
Name Type Default Notes
length float 320.0
height float 76.0
waves float 5.0
counter float 8.0
lines int 18
center Point (0.0, 0.0)
resolution int | None None Segments per strand -- a strand gets one more point than that, so both ends are included. None (default) scales density with the winding.

guilloche.pattern

guilloche.pattern

A rosette inside a woven border, with rules between: the banknote layout.

from geomotif import save_svg
from geomotif.motifs import GuillochePattern

motif = GuillochePattern(layers=5, border_lines=8, border_waves=18.0)
save_svg(motif.build(), "guilloche.pattern.svg", width=320, height=320)

geomotif render guilloche.pattern --out guilloche.pattern.svg

  "motif": "guilloche.pattern",
  "params": {
    "radius": 150.0,
    "layers": 5,
    "petals": 11.0,

guilloche.rosette

guilloche.rosette

A stack of rosettes, each turned a little further than the last.

from geomotif import save_svg
