Subject: bug#4016: 23.1.50; docview: scrolling up breaks after setting a slice
Date: Sun, 02 Aug 2009 16:07:35 +0200	[thread overview]
Message-ID: <yqz5a7hxm8g2g.fsf@shell-1.math.kth.se> (raw)


Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org
mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


View a dvi file (or pdf file for that matter) with DocView.

Set a slice by typing "ss" (invoking doc-view-set-slice) with x and y
coordinates zero, and maximum width and height, as suggested by the
prompt.  (In fact, any slice settings seems to trigger the phenomena.)

When hitting space (invoking doc-view-scroll-up-or-next-page), the
document is not scrolled up, and the following error message appears:

image-next-line: Invalid image specification

Note: By hitting "sr" (removing the slice) it is again possible to use
space to scroll up.

Remark: On a laptop with a small screen it would be very useful to set
slices to get rid of the large margins, and yet being able to scroll
through the document (even with a slice set, I cannot see the whole
page at once.)



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1.50/etc/DEBUG for instructions.
