I've just tried with a Thesis containing 617 equations. It took gs
about 5 mins to do the work. Thereafter LyX freezes until all these
images are loaded up into memory.
That's not good.
I think we'll have to do something about that. Presumably the
elegant solution of loading an image file as it is created might
aleviate this problem somewhat.
That's not a good solution. The good solution would be to load only
those images that actually appear on-screen. Often in a single
editing session, you will not even be looking at most of the
document. No need to be loading the stuff into memory in the first
place, then.
Agreed. Currently I just do:
void Previews::generateBufferPreviews(Buffer * buffer)
{
if (!buffer || !lyxrc.preview)
return;
PreviewLoader ploader = loader(buffer);
Buffer::inset_iterator it = buffer-inset_const_iterator_begin();
Buffer::inset_iterator end = buffer-inset_const_iterator_end();
for (; it != end; ++it) {
if ((*it)-lyxCode() == Inset::MATH_CODE) {
(*it)-generatePreview(ploader);
}
}
ploader.startLoading();
}
I'm sure that the wizards will be able to help here. Wizards, are you reading
this? I'd like to generate small batches of these previews, say for the first
three or four screen heights. Thereafter, if I arrive at an inset for which a
preview hasn't been generated, I'd like to generate previews for three or
four screen heights around it. Any thoughts on an interface?
Anyway, the current implementation is certainly Ok for 30 or 40 equations.

label of equation with preview
Hi, the preview is a very nice feature!
It is possible to put the label of the equation instead of his number :
Replace
\begin{equation} bal bla bla \label{eq:blabla} \end{equation}
by
\[ bal bla bla \eqno{ \rm{ (eq:blabla) }} \]
It can be nice, no?

Re: label of equation with preview
an other solution is to replace the command \label by \tag. If you put a
label, it must be put after the tag command.
This solution need amsmath.
\begin{equation}
\int x \ dx
\tag{ \rm{eq:1} }
\end{equation}

PreviewLoader & ploader = loader(buffer);
Buffer::inset_iterator it = buffer->inset_const_iterator_begin();
