CharCorpus

class text_renderer.corpus.CharCorpus(cfg: CorpusCfg)

Randomly sampling a certain length of strings from the corpus

class text_renderer.corpus.CharCorpusCfg(font_dir: ~pathlib.Path, font_size: ~typing.Tuple[int, int], font_list_file: ~pathlib.Path | None = None, clip_length: int = -1, char_spacing: float | ~typing.Tuple[float, float] = -1, text_color_cfg: ~text_renderer.config.TextColorCfg = <factory>, horizontal: bool = True, text_paths: ~typing.List[~pathlib.Path] = <factory>, length: ~typing.Tuple[int, int] = (5, 10), filter_by_chars: bool = False, chars_file: ~pathlib.Path | None = None, filter_font: bool = False, filter_font_min_support_chars: int = 100)

Char corpus config

Parameters:

• text_paths (List[Path]) – Text file paths

• length (Tuple[int, int]) – Range of output text length [min_length, max_length)

• filter_by_chars (bool) – If True, filtering text by character set

• chars_file (Path) – Character set

• filter_font (bool) – Only work when filter_by_chars is True. If True, filter font file by intersection of font support chars with chars file

• filter_font_min_support_chars (int) – If intersection of font support chars with chars file is lower than filter_font_min_support_chars, filter this font file.

Base config for corpus

Parameters:

• font_dir (path) – font files directory

• font_list_file (path) – font file names to load from font_dir, if not provided, all fonts in font_dir will be used

• font_size (tuple[int, int]) – font size in point (min_font_size, max_font_size)

• clip_length (int) – clip get_text() output. set -1 disables clip

• char_spacing ((Union[float, tuple[float, float]])) – Draw character with spacing. If tuple, random choice between [min, max) Set -1 to disable

• text_color_cfg (TextColorCfg) – see TextColorCfg. has higher priority than RenderCfg.text_color_cfg

• horizontal (bool) – generate the horizontal(default) or vertical text Set False to generate vertical text
