Variables

ascent double ascent;: The distance in pixels from the text baseline to the highest/upper grid coordinate used to place an outline point. Always a positive value.
bounds SegmentInfo bounds;: This is an imaginary box that encloses all glyphs from the font, usually as tightly as possible.
descent double descent;: The distance in pixels from the baseline to the lowest grid coordinate used to place an outline point. Always a negative value.
height double height;: Text height in pixels.
max_advance double max_advance;: The maximum horizontal advance (advance from the beginning of a character to the beginning of the next character) in pixels.
origin PointInfo origin;: A virtual point, located on the baseline, used to locate glyphs.
pixels_per_em PointInfo pixels_per_em;: Horizontal (x) and vertical (y) pixels per em.
underline_position double underline_position;
underline_thickness double underline_thickness;
width double width;: Text width in pixels.
