Align to Path moved the whole line by the largest ascent and descent among its characters. Each character now moves by its own font, size and vertical scale. Ascender runs the top of the font's em box along the path: the ideographic em box that the font's BASE table gives, or in a Chinese, Japanese or Korean font the one that its typographic or hhea box, a one-em box-drawing cross or its ideographs give; else an em box centered on the cap height. Descender runs the bottom of the font's bounding box along the path, and Center runs a line at half the height of the top of the font's H along it. In vertical type, Ascender and Descender move the characters half an em, and Center leaves them on the path. Existing documents with Align to Path set to Ascender, Descender or Center lay their type out at a new distance from the path.
