Creating Stroke-Ordered Paths from KanjiVG

The StrokePaths group in KanjiVG contains each stroke as an SVG path, ordered by stroke sequence. FontKanjiVGStrokeLoader preserves this order when generating FontStrokeGlyph.

from pathlib import Path

from glyph_motion.lib.font_kanjivg_stroke_loader import FontKanjiVGStrokeLoader
from glyph_motion.lib.font_viewer import FontViewer

loader = FontKanjiVGStrokeLoader(
    kanjivg_directory=Path("kanjivg/kanji"),
    height=40.0,
    spacing=5.0,
    curve_division=20,
)

stroke_glyph = loader.load_text(text="島根")

print("stroke_count =", len(stroke_glyph))

viewer = FontViewer()
viewer.show_stroke(stroke_glyph=stroke_glyph)

SVG filenames

SVG files are located using the Unicode code point of the target character. For example, 島 is U+5CF6, so its filename is 05cf6.svg.

Coordinate transformation

The loader reads the SVG viewBox and scales the coordinates to the specified height. It also converts SVG’s downward-pointing Y coordinates into the coordinate system used for visualization and robotic processing.

Supported path commands

SvgPathSampler processes the following SVG path commands:

M, m
L, l
H, h
V, v
Q, q
T, t
C, c
S, s
Z, z

Quadratic and cubic Bézier curves are converted to point sequences according to curve_division.
