BaselinePosition

BaselinePosition
is an option which specifies where the baseline of an object is considered to be for purposes of alignment with surrounding text or other expressions.

MORE INFORMATION

BaselinePosition is an option for such objects as Graphics, Grid and TabView.

BaselinePosition->pos specifies that position pos in an object should align with the baseline of surrounding text or other expressions.

Possible settings for BaselinePosition are:

	Automatic	default object baseline
	Bottom	bottom of object
	Top	top of object
	Center	halfway between top and bottom
	Axis	axis of the object
	Baseline	baseline of the first text line
	Scaled[y]	fraction y of the height of the object
	i	baseline of row i in a grid
	{i,j}	baseline of element i,j in a grid
	{{i,j},pos}	position pos in element i,j
	pos->ref	baseline offset to make pos be aligned with ref

Scaled[0] corresponds to the bottom of the object; Scaled[1] to the top. If y is outside the range 0 to 1, Scaled[y] gives a baseline that lies outside the object.

For most objects BaselinePosition->Automatic specifies that the center of the object should align with the axis of surrounding text, corresponding to BaselinePosition->(Center->Axis).

For objects that contain lines of text, BaselinePosition->Baseline specifies that the baseline of the whole object should be taken to be the baseline of the first line of text.

For text, the position of the axis is determined by the placement of - or a similar character. For other objects, the axis is taken to be the center, except when a construct such as a fraction bar or graphics axis defines another natural choice.

In BaselinePosition->(pos->ref )the reference point ref can be Baseline, Axis, Bottom, Top, or Center. It can also be Scaled[y], where y represents a fraction of the total height of a single line of text in the current font.
