Whizzytex Zooming

Whizzytex Zooming

Hello list

Yesterday I found the Whizzytex package and it seems to comfort my
work enormously. But I have an annoying difficulty to set the correct
zoom factor.

I'm using dual head, having Emacs on the left screen, and the
dvi-viewer on the right one. When I use xdvi I set the zoom factor to
4. This displays about half of the page in an easy-to-read font size,
what suits my needs best.

Whizzytex uses advi by default. The default zoom factor of advi is
much too small for my eyes. It can be increased by one factor (I think
once the radix of 2) but it falls back to its original size as soon as
I move the point in Emacs. It's also possible to maximize the advi
window to fit the screen but this also increases the zoom factor only
by one step. The left half of the window is showing the page, the
right half is completely white. It's not possible to further increase
the zoom factor when the window is maximized. The problem seems to be
that advi is resolute in always showing one whole page of the document
in full.

When advi is started from a shell the option -nocrop solves the
problem. Then it's possible to zoom virtually ad infinitum (hitting
the > key).

But how can this be achieved using Whizzytex? The whizzy-help seems to
be silent on this point, otherwise I must have overlooked it (I'm not
very good in evaluating the power of odd configuration hints in
manuals). 

Does anybody have a solution for this problem?

Thanks for help,

Sven

P.S. setting Whizytex's default viewer to xdvi doesn't seem to
work. xdvi just remains fixed on the first page.

PP.S. I'm on KDE under Debian Etch with Emacs 22.1.50.1 and whizzytex
1.3.0.

I figured it out myself. It's explained in the advi
documentation. It's just to write an init file for advi ~/.advirc
containing the line `-nocrops'.

But the problem isn't solved yet. When I enlarge the advi zooming
factor so that only about half of the page is visible in a nice large
fontsize, the rest of the page is never displayed. When I move the
point in the Emacs buffer to a line belonging to the lower half of the
output page, advi's display doesn't follow the move.

So I tried to set xdvi as the default viewer of whizzytex. But it's
even worse here. xdvi doesn't even follow if the point is moved beyond
a pagebreak. It just remains fixed at the first page.

Is it really only possible to fully use whizzytex if you let advi
display the whole page at once (i.e. in a quite small fontsize)? Or am I
missing sonething essential?

Greetings,

Sven
