7.4 Converting from StarMath with a Basic macro

In addition to converting a complete document, you can also convert a single formula from StarMath to LaTeX. To do this, the uno service

org.openoffice.da.writer2latex.W2LStarMathConverter

is provided. This service supports two methods

string convertFormula ( [in] string sStarMathFormula );

string getPreamble ( );

• The method convertFormula converts a StarMath string to a LaTeX string

• The method getPreamble returns a LaTeX preamble suitable for processing the converted formulas.

This small example is a Basic macro that converts a few formulas and displays the result. Note that the last conversion triggers a definition of the LaTeX macro \defeq in getPreamble().

Dim smc As Object

smc = CreateUnoService( _

    "org.openoffice.da.writer2latex.W2LStarMathConverter")

MsgBox smc.convertFormula("1 over 2")

MsgBox smc.convertFormula("int from 1 to infty f(x)dx")

MsgBox smc.convertFormula("sqrt 3")

MsgBox smc.convertFormula("f(x) def x^2-1")

MsgBox smc.getPreamble()
