To draw TeX Mathematical Formula

TMathText's purpose is to write mathematical equations, exactly as TeX would do it. The syntax is the same as the TeX's one.

The following example demonstrate how to use TMathText:

{
TCanvas *c1 = new TCanvas("c1");
l.SetTextAlign(23);
l.SetTextSize(0.06);
l.DrawMathText(0.50, 1.000, "\\prod_{j\\ge0} \\left(\\sum_{k\\ge0} a_{jk}z^k\\right) = \\sum_{n\\ge0} z^n \\left(\\sum_{k_0,k_1,\\ldots\\ge0\\atop k_0+k_1+\\cdots=n} a_{0k_0}a_{1k_1} \\cdots \\right)");
l.DrawMathText(0.50, 0.800, "W_{\\delta_1\\rho_1\\sigma_2}^{3\\beta} = U_{\\delta_1\\rho_1\\sigma_2}^{3\\beta} + {1\\over 8\\pi^2} \\int_{\\alpha_1}^{\\alpha_2} d\\alpha_2^\\prime \\left[ {U_{\\delta_1\\rho_1}^{2\\beta} - \\alpha_2^\\prime U_{\\rho_1\\sigma_2}^{1\\beta} \\over U_{\\rho_1\\sigma_2}^{0\\beta}} \\right]");
l.DrawMathText(0.50, 0.600, "d\\Gamma = {1\\over 2m_A} \\left( \\prod_f {d^3p_f\\over (2\\pi)^3} {1\\over 2E_f} \\right) \\left| \\mathscr{M} \\left(m_A - \\left\\{p_f\\right\\} \\right) \\right|^2 (2\\pi)^4 \\delta^{(4)} \\left(p_A - \\sum p_f \\right)");
l.DrawMathText(0.50, 0.425, "4\\mathrm{Re}\\left\\{{2\\over 1-\\Delta\\alpha} \\chi(s) \\left[ \\^{g}_\\nu^e \\^{g}_\\nu^f (1 + \\cos^2\\theta) + \\^{g}_a^e \\^{g}_a^f \\cos\\theta \\right] \\right\\}");
l.DrawMathText(0.50, 0.330, "p(n) = {1\\over\\pi\\sqrt{2}} \\sum_{k = 1}^\\infty \\sqrt{k} A_k(n) {d\\over dn} {\\sinh \\left\\{ {\\pi\\over k} \\sqrt{2\\over 3} \\sqrt{n - {1\\over 24}} \\right\\} \\over \\sqrt{n - {1\\over 24}}}");
l.DrawMathText(0.13, 0.150, "{(\\ell+1)C_{\\ell}^{TE} \\over 2\\pi}");
l.DrawMathText(0.27, 0.110, "\\mathbb{N} \\subset \\mathbb{R}");
l.DrawMathText(0.63, 0.100, "\\hbox{RHIC スピン物理 Нью-Йорк}");
c1->Print("c1.gif");
c1->Print("c1.jpg");
c1->Print("c1.png");
c1->Print("c1.ps");
c1->Print("c1.eps");
return c1;
}

The list of all available symbols is given in the following example:

Limitation:

TMathText rendering is not implemented for the PDF output. PostScript output should be used instead.
