MathBuildDown function
Translates the builtup math, ruby, and other inline objects in the specified range to linear form.
Syntax
HRESULT MathBuildDown(
_Inout_ ITextRange2 *prg,
_In_ ITextStrings *pstrs,
_In_ long Flags
);
Parameters
 prg [in, out]

Type: ITextRange2*
On input, a text range object that contains the builtup math objects to convert to linear form. On output, the object contains the linear form.
 pstrs [in]

Type: ITextStrings*
Strings collection used for manipulations.
 Flags [in]

Type: long
A combination of the following flags.
Return value
Type: HRESULT
See Remarks.
Remarks
If the linearization is successful, the originally selected range is replaced by the linearized version.
If the tomMathRemoveOutermost or tomMathBuildDownOutermost build down mode is specified, the build down operation can be affected by the tomMathChangeMask values. The main purpose of these builddown modes is to facilitate transformations of the buildup math object as exposed by math context menus.
For example, to convert a stacked fraction to a linear fraction as in (a+b/c)/(u+x/y)→((a+b/c))⁄((u+x/y)), parentheses must be inserted; otherwise, you get a transformation that looks incorrect, as in (a+b/c)/(u+x/y)→(a+b/c)⁄(u+x/y), even though internally the linear fraction still has the original numerator and denominator.
The builddown process automatically inserts the parentheses, because the linear format for this case has parentheses, and the special change is made to replace the stackedfraction operator U+002F by the linear fraction operator U+2215. Build up doesn't discard the parentheses for U+2215, but it does for U+002F.
