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.
The problem comes with the large height and (or) depth formulae.
Usually such a formula as
for example has
larger height, then depth and there may be inproper large gap (vskip) before the next
line. The situation of equal height and width
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:
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.
The simple convertion algorithm can fail in the two reasons:
The second is not a font bugs,
it is a basic TEX feature, Convertion algorithm designer hate it, but have absolutely no chance
to change it generaly and therefore he can not trust LATEX box dimentions.
- Usable image convertion libraries and tools do not care
reference point position in the image while cropping
- LATEX box dimensions (width, height and depth) usually
differs from its visual width, height, or depth.
All dots in the line are to be exactly alighned for any browser and selected text size.
