dominantBaseline and
alignmentBaseline properties of the ElementFormat class. You can also use it in the
baselineZero property of the TextBlock class.
Consider this situation:
The line consists of four TextElement objects, containing 'a', 'b', 'cccccccc', and 'X' respectively.
The element containing 'X' determines the line baselines because it is the largest element in the line.
The roman baseline of the 'X' element is aligned with the roman baseline of the line.
The ideographic top of the 'a' element is aligned with the ideographic top of the line.
The ideographic bottom of the 'b' element is aligned with the ideographic bottom of the line.
The ideographic center of the 'cccccccc' element is aligned with the ideographic center of the line.
