At a lower level, Ziafont can also draw individual glyphs. The glyph for a string character can be obtained from
ziafont.font.Text(), this method returns a Glyph object with methods for returning SVG as a string or as an SVG XML element.
<Element 'svg' at 0x7f027a24a860>
The above svg and svgxml methods both return the glyph in a standalone SVG. Often, however, the glyph should be added to an existing drawing or used elsewhere. The svgpath method returns the glyph as an SVG <path> element that can be inserted in an existing SVG. Alternatively, the svgsymbol method wraps the <path> in an SVG <symbol> element that can be reused multiple times in the same drawing.
In addition to the glyph symbol, each glyph contains information about its bounding box. To view the bounding box and baseline of a glyph, use the test method:
Notice how some glyphs can extend below the baseline (red).
The glyph index refers to its position within the font file, not necessarily the unicode representation of the character. The index for a given character in the font can be obtained:
