annotate_figure_grid_layout — ANNOTATE paper op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.annotate_figure_grid_layout(shapes, ncols=2, pad=10, caption_h=32, title_h=0, letter_style='paren') (to call the implementation directly, import annotate; annotate.annotate_figure_grid_layout(shapes, ncols=2, pad=10, caption_h=32, title_h=0, letter_style='paren'); from the registry, opsannotate.get("annotate_figure_grid_layout"))

Usage

Returns a table (dict): the typesetting of a multi-panel figure (cell, panel and caption-band rectangles) in closed form.

The same formulas as panel_grid: cw/ch is the largest panel size, W = 2*pad + ncols*cw + (ncols-1)*pad, H = title_h + 2*pad + nrows*(ch+caption_h) + (nrows-1)*pad. Panels are not enlarged; they are centred in their cells.

Returns

dict

{"size":(H,W), "cells":[(x,y,cw,ch)], "panels":[(x,y,w,h)], "captions":[(x,y,cw,caption_h)], "letters":[str], "ncols", "nrows"}.

Raises

ValueError

shapes is empty, ncols < 1, negative padding, or more than 26 panels.
