ocr_font — SYMBOL `ocr` 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.ocr_font(name: 'str' = 'dot5x7') -> 'dict' (to call the implementation directly, import ocrclassic; ocrclassic.ocr_font(name: 'str' = 'dot5x7') -> 'dict'; from the registry, opssymbol.get("ocr_font"))

• GPU: none (CPU reference implementation only)

Usage

Return the charset and glyph designs of a built-in font (5x7 dot matrix / stroke) (table).

> The detailed description below is the original text — the summary and the headings are translated.

Parameters

name : "dot5x7" か "stroke"。

Returns

dict

name, charset (str), glyphs (char -> design: dot5x7 は (7,5) uint8 のビットマップ、

stroke は折れ線のリスト [[(x, y), ...], ...]), kind ("dot"/"stroke"),

grid (設計格子の (行, 列) または (高さ, 幅)), advance (設計単位の送り幅:

dot5x7 = 6 ドットピッチ、stroke = 6 格子単位)。

返す辞書は毎回新しい複製なので、呼ぶ側が字を足して ocr_render_text(font=<dict>) に

渡してよい(字種外の試験字を作る用途)。

Raises

ValueError

未知の書体名。
