View source for SFN:TeX4ht: TeX to HTML/MathML — conversion issues

[[Main_Page||Back|]]

The main problems that we faced when converting the T<sub>E</sub>X sources of Project Gutenberg Ebooks to HTML5/MathML formats are listed here.

==HTML==
# Text coded using <code>{\itshape ...}</code> not appeared as italic.

==MathML==
# The footnote counter in display equations appear in a new line without a link to its corresponding footnote text.
# <code>\textstyle</code> does not work for fractions.
# <code>\intertext</code> in <code>{gather}</code> is not rendered. It has converted in MathML, but rendering failed due to wrong tagging.
# <code>\limits</code> in inline equations does not produce the desired output.
# The equation number coded in <code>\tag{}</code> in starred display math environments (eg: <code>equation*, eqnarray*, align*</code> etc.) render without right alignment like normal equation number.
# <code>\makebox[][]{}</code> does not produce any code.
# The font of equation number differs for equations coded in <code>{equation}, {eqnarray}</code> or any amsmath environements like <code>{align}, {gather}</code> etc.
# The alignment of equations coded in <code>{aligned}</code> environment completely lost when <code>\textit</code> was used instead of <code>\mathit</code>.
# The aboveskip of an equation is too small when it appears inside a list.
