Re: Extent boundaries inconsistent w.r.t. extent properties
On Mon, 15 Apr 2002, Michael Toomim stipulated:
With the system proposed earlier, you can affect extent glyph
visibility by changing the extent's invisible property. That seems to
work perfectly for both Nix's application and my application.
It doesn't work perfectly for preview-LaTeX. e.g., the following
document gets mis-rendered:
\documentclass[a4paper]{article}
\begin{document}
\section{Foo Bar}
This will malfunction: $a+b$$c+d$ loses its first preview. Stick a
space in between those textmaths and it will work.
So there. :)
\end{document}
because the first preview (for the first textmath section) is rammed
hard up against another one; both are marked 'invisible (to stop the
text getting displayed while the previews are visible) and both have
end-glyphs, but because the first preview's end-glyph is at the same
location as the start of invisible text, the glyph disappears.
This can't be fixed from Lisp.
Anyway, I don't think I'm going to be writing the patch for
this
anytime soon, if I ever do.
Looks like I'll have to then. It's hardly top of my list, though:
currently, getting my redisplay patch in and fixing the problem
seemingly causing glyphs to be garbaged if they're instantiated in
buffers other than the current one are my priorities...
