annotate_text_path — ANNOTATE `paper` op

• Data kinds: image2d × text → image2d

• Call: import fullseye as fs; fs.ledger.annotate_text_path(img, text, path, font_size=13, color='neutral', spacing=1.0, start=0.0, draw_path=False, width=1.0, scheme='okabe_ito', font_path=None, layout=None, anchor='start', offset=0.0, upright=False, line_spacing=1.15, bold=False, italic=False) (to call the implementation directly, import annotate; annotate.annotate_text_path(img, text, path, font_size=13, color='neutral', spacing=1.0, start=0.0, draw_path=False, width=1.0, scheme='okabe_ito', font_path=None, layout=None, anchor='start', offset=0.0, upright=False, line_spacing=1.15, bold=False, italic=False); from the registry, opsannotate.get("annotate_text_path"))

Usage

Returns an image (image2d): text set along a polyline (each glyph rotated to the tangent angle).

文字の板は敷かない(経路の上に載せる用途なので)。配置と、

`anchor / offset / upright(縦書き)/ \n` による改行の意味は

:func:annotate_text_path_layout に書いてある。

`layout` を渡した場合、そちらがそのまま使われる ——

`anchor` などは無視されるので、両方を渡さないこと。

`bold / italic は**合成**(:func:_bold_px / :func:_italic_tile`)。

1 字ずつ焼いてから回すので、傾きは字の縦軸に対して掛かる(経路が

斜めでも斜体が経路の向きに歪まない)。

Raises

------

ValueError

:func:annotate_text_path_layout と同じ + 回転した字が画像の外に出る。
