Subject: 30.0.50; image-mode: scroll and resize
Date: Mon, 28 Aug 2023 15:08:24 +0200

Hi,

When using image-mode, I have some minor issue with scrolling and then
resizing.  For example, if you have a big image that you view in its
original size with 'image-transform-reset-to-original' (s o) and then
scroll into it (with C-f/C-n…)

If you get back to the default 'fit-to-window' (s w), the horizontal and
vertical scroll is kept and it places the image oddly into the window.
I have a patch to reset the scrolling when a such a resizing occur but
I'm not sure this is the best thing to do.

Best regards,
