Hi Bill,

Yes, I've fixed that. And I've sent it to emacs-devel for inclusion.
There's the new slicing-feature you're going to love! Trust me!

That was a typo and it's fixed now.

That's what I did, because C-v/M-v are always bound to scroll-up/down.

i've just downloaded it and tried to compile, but my emacs chokes on
'defparameter'. the elisp manual doesn't mention defparameter, (require
'cl) also doesn't help, the emacs wiki site nor the source code mention any
requirements that i don't have, and i haven't been able to find any
relevant info on google... so please tell me, how do i get this elusive
defparameter?

TIA

Hi Joost,

But that was just a typo. Please update, I removed it.

[defparameter]

ah, thanks. (i already replaced it with defvar, figuring that that way, it
would at least work. ;-)

btw, since my screen is rather small (12inch ibook), a converted page isn't
shown in full, and i have to scroll down to see the bottom part. (slicing
doesn't help, as the screen is just too small.) other viewers (xdvi, xpdf)
usually use the space bar to scroll down and jump to the top of the next
page if the bottom of the page is shown. usually, DEL or backspace does the
opposite.

i've been trying to implement this functionality for doc-view, but so far
without much luck. it turns out to be rather difficult to establish which
part of the image is actually shown in the active window. i've tried with
pos-visible-in-window-p and with window-start/window-end, but that doesn't
really work. do you perhaps know a better way to do this?

TIA

Hi Joost,

You can still slice with:

,----[ C-h f doc-view-set-slice RET ]
| doc-view-set-slice is an interactive Lisp function in `doc-view.el'.
| (doc-view-set-slice X Y WIDTH HEIGHT)
|
| Set the slice of the images that should be displayed.
| You can use this function to tell doc-view not to display the
| margins of the document. It prompts for the top-left corner (X
| and Y) of the slice to display and its WIDTH and HEIGHT.
|
| See `doc-view-set-slice-using-mouse' for a more convenient way to
| do that. To reset the slice use `doc-view-reset-slice'.

hi tassilo,

yes, i saw that function. however, the thing is, the text itself is simply
too large to fit on my screen. ;-) telling doc-view to create smaller
images wouldn't work either, because then the text becomes too small to
read.

Looks like a defparameter snuck into that last commit. You should change
it to a defvar.

I do not see what the typo you are talking about is. Where is the
error in this code snipet ?

the code snippet does not have a typo, it's tassilo's reply to my question
how to get defparameter in elisp. the typo is the fact that there was a
defparamater in his code.
