class ziafont.font.Font(name: Optional[Union[str, Path]] = None, style: str = 'regular')

Class to read/parse a OpenType/TTF and write glyphs to SVG

Parameters

  • name – File name of the font

  • style – Font style such as “bold” or “italic”, used when searching system paths for a font file

advance(glyph1: int, glyph2: Optional[int] = None, kern: bool = True)

Get advance width in font units, including kerning adjustment if glyph2 is defined

getsize(s) → tuple[float, float]

Calculate width and height (including ascent/descent) of string

glyph(char: str) → SimpleGlyph

Get the Glyph for the character

glyph_fromid(glyphid: int) → Union[SimpleGlyph, CompoundGlyph]

Read a glyph from the “glyf” table

Parameters

glyphid – Glyph index used to find glyph data

glyphindex(char: str) → int

Get index of character glyph

text(s: str, size: Optional[float] = None, linespacing: float = 1, halign: Literal['left', 'center', 'right'] = 'left', valign: Literal['base', 'center', 'top'] = 'base', color: Optional[str] = None, rotation: float = 0, rotation_mode: str = 'anchor', kern=True)

Create a Text object using this font

Parameters
usecmap(cmapidx: int) → None

Select cmap table by index. Only supported tables are included.

verifychecksum()

Verify checksum of all font tables. Raises ValueError if invalid

class ziafont.font.Text(s: str, font: Optional[Union[str, Font]] = None, size: Optional[float] = None, linespacing: float = 1, halign: Literal['left', 'center', 'right'] = 'left', valign: Literal['base', 'center', 'top'] = 'base', color: Optional[str] = None, rotation: float = 0, rotation_mode: str = 'anchor', kern: bool = True)

Draw text as SVG paths

Parameters
