Dear Emacs developers,
To reproduce starting from 'emacs -Q' visit an image file. Then
repeatedly use 'i +' till the image is taller than the window. The
image can be scrolled using mouse wheel. Now do
M-x pixel-scroll-precision-mode
After this attempting to scroll the image will set the vscroll to 0
and then image can't be scrolled at all.
>From some investigation it seems like this behavior is not specific
to image-mode. Another way to reproduce the behavior is to evaluate
the following lisp code,
(let* ((win (display-buffer (get-buffer-create "image-pixel-precision-test")))
(height (* (window-text-height win t) 2))
(file "path/to/image"))
(select-window win)
(erase-buffer)
(insert-image (create-image file nil nil))
(goto-char 1)
(pixel-scroll-precision-mode)
nil)
This image thus displayed can not be scrolled. However if the code
above is slightly modified to insert a new line after the image,
scrolling can be done normally, i.e.
(let* ((win (display-buffer (get-buffer-create "image-pixel-precision-test")))
(height (* (window-text-height win t) 2))
(file "path/to/image"))
(select-window win)
(erase-buffer)
(insert-image (create-image file nil nil))
(insert "\n")
(goto-char 1)
(pixel-scroll-precision-mode)
nil)
produces an image that can be scrolled. Inserting a newline after the
text covered by the text property holding the image also fixes the
problem in 'image-mode' but that doesn't seem like the right fix to me.
