The trap for LATEX convertors

Sergej V. Znamenskij

This file contains absolutely legal and ordinary (thought somevhere miningless) mathematical constructions in LATEX text to facilitate visual detection of image alignement algorithm flaws in LATEX to HTML convertion.

Lines alignement problem

The problem comes with the large height and (or) depth formulae. Usually such a formula as $x_s^{\int\limits_a^{N^1}\, dx}$ for example has larger height, then depth. As a corollary, converto may add inproper large gap (vskip) before the next line. The case of equal height and width $\left(x_s^{\int\limits_a^{N^1}\, dx}\right)$ is more controllable, as far as we do not try to get images scaled togater with text changing. The other most rare and very hard to resolve situation is a formula with a large depth, but a very small height: $y=1-\dfrac{\alpha}{1-\dfrac{2}{3-\dfrac{4}{5-x}}}$. I will appreciate any idea to keep proper interline distance in such a case without additional vskip over this formula thought suppoce it to be impossible: I failed to find a hint in html specifications how to force browser to leave a proper place lower image witout extra gup over it.

Inline alignement problems

All dots in the line are to be exactly alighned for any browser and selected text size.

The simple convertion algorithm can fail due to the following reasons:
