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
