"default" and "regular" are synonyms and use the non-math font. font_class : str One of the TeX font names (as for *font*), but **not** "bb", "frak", or "scr". This is used to combine two font classes. The only supported combination currently is ``get_metrics("frak", "bf", ...)``. sym : str A symbol in raw TeX form, e.g., "1", "x", or "\sigma". fontsize : float Font size in points. dpi : float Rendering dots-per-inch. Returns ------- object The returned object has the following attributes (all floats, except *slanted*): - *advance*: The advance distance (in points) of the glyph. - *height*: The height of the glyph in points. - *width*: The width of the glyph in points. - *xmin*, *xmax*, *ymin*, *ymax*: The ink rectangle of the glyph - *iceberg*: The distance from the baseline to the top of the glyph. (This corresponds to TeX's definition of "height".) - *slanted*: Whether the glyph should be considered as "slanted" (currently used for kerning sub/superscripts). ) _get_infor])r;rA font_classsymrBrrHs r/ get_metricszFonts.get_metricss&H~~dJXsCC|r=c r||||||} |j||| fdS)z At position (*ox*, *oy*), draw the glyph specified by the remaining parameters (see `get_metrics` for their detailed description).
