I also tried the patch on current trunk. I use the following snippet to
generate a buffer containing large and small images as well as text:
(with-current-buffer (get-buffer-create "test")
(erase-buffer)
(let ((imagelarge (create-image "~/someimage.jpg" 'imagemagick nil :height
2000 :width 1000))
(imagesmall (create-image "~/someimage.jpg" 'imagemagick nil :height
200 :width 100)))
(dotimes (i 20)
(insert "\n*** " (number-to-string i)" ***\nThis is a line of text.\nAnd
here's a large image:\n")
(insert-image imagelarge)
(insert "\nAnd a small image:\n")
(insert-image imagesmall))
(goto-char (point-min))))
Obviously, replace "~/someimage.jpg" with something else. Also, Emacs
must be compiled with imagemagick support.
Scrolling using your patch looks already pretty good, but I also get the
'wrong-type-argument' error while scrolling down. I use a maximized
'emacs -Q' on a display with 1366x768 resolution, and here's the backtrace:
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
line-move-partial(1 nil nil)
line-move(1 nil nil 1)
#[0 "\302\300@\303\211\301$\207" [(1) 1 line-move nil] 5 "\n\n(fn)"]()
funcall(#[0 "\302\300@\303\211\301$\207" [(1) 1 line-move nil] 5 "\n\n(fn)"])
next-line(1 1)
call-interactively(next-line nil nil)
command-execute(next-line)
This happens during scrolling when point should switch from the first
small image to the following text line containing "*** 1 ***". The
second large image is already visible at the bottom. I can do
screenshots or even a screencast if necessary.
