annotate_dimension — ANNOTATE `paper` op

• Data kinds: image2d → image2d

• Call: import annotate; annotate.annotate_dimension(img, p0, p1, units_per_pixel=1.0, unit='px', offset=20.0, extension=6.0, color='neutral', width=1.5, head_len=9.0, head_width=6.0, label_fmt='{:.1f}', font_size=11, box_alpha=0.6, text_color=None, scheme='okabe_ito', font_path=None, layout=None) (or opsannotate.get("annotate_dimension"))

Usage

Returns an image (image2d): a dimension line (arrowheads at both ends, extension lines, value and unit).
