background-image in emacs

background-image in emacs

[M G Berberich]

Hello,

at the moemnt I'm using xemacs, and I have a background-image, which
improves usability (in my opinion). Is there a way to get this
appearance in emacs too?

(see: http://www.forwiss.uni-passau.de/~berberic/xemacs-bg.png)

How does this work for lines broader than the buffer?

It looks surely interesting.  But normally the readability of text
presented in lines is good when they aren't too long.

The only advantage I discern is when comparing stuff by hand
i. e. checking data presented in tabular form and your eyes have to
wander constantly from the sheet to the screen and might end up in the
wrong line.

This reminds me a bit of `global-hl-line-mode'.

I'm not sure if I understood your question: It's simply a
background-image, belonging to the frame. It does not care about
»logical« lines. It's like printing on old-fashioned fanfold
computer-paper.

I normaly don't do this. I like it and think its usefull in editing
"formated" texts, like source-code.

That's a nice feature, but not what I want. It is useful for your
exmaple above, but, as I said, that's not what I'm doing.

I see, it's a pity, it could be an alternative to the fringe's
indicators of long lines.

Hmmm, I really had to work with it to judge the usefulness.

It might be possible to implement that using overlays but I am not
sure how the performance would be. Maybe someone else he can make a
simple prototype?
