Package: emacs
Version: 24.0.93
Severity: wishlist
thumbs.el and image-dired.el both rely on using external ImageMagick
utilities to resize/rotate images.
If Emacs was compiled with ImageMagick support, then images of
type imagemagick can be resized and rotated internally (see
image-transform-*). These modes should use the internal support if
it exists.

So now that we have native image rotation and ImageMagick is on its
way to become deprecated, I assume that this bug should be taken to
mean that we want to use the built-in support here instead.

Hmm, looking closer at this, both thumbs.el and image-dired.el modifies
the actual image file. This is something that our built-in support
can't do, as we only have support for reading images.
However, the ImageMagick library has these capabilities. Given that we
no longer compile with ImageMagick by default, I don't think this
request makes any sense as it stands. Perhaps we could implement the
in-memory rotation in addition to the modifying one that we have now,
but this is unlikely to be very useful. If I rotate an image in an
image viewer, it is almost certainly because I want to update the file;
at least this is always the case in my use.
Jpeg images can of course be losslessly rotated by just modifying the
exif data, so implementing built-in support for rotating jpeg images
seems quite doable. However, we would still not be able to drop the
external imagemagick dependency, because we would then also lose the
capability to rotate other image formats.
So perhaps this feature request is relevant anymore. WDYT?

I now see that Glenn mentioned resizing as well, where using the
built-in image scaling seems very relevant. We currently jump through
some unnecessary hoops in `image-dired-display-image' when we could just
resize the image in memory.
Is there any reason why `image-dired-display-image-mode' doesn't just
inherit `image-mode'? That would avoid code duplication and also allow
us to immediately benefit from any improvements to `image-mode'.

Resending to include Mathias Dahl in the conversation.
(I missed removing ".rem0veth1s" from his listed email address.)

Hi, sorry for coming late to the party.
I cannot remember any good reason for not inheriting from `image-mode', but
I opened image-dired.el now and found this:
(defvar image-dired-display-image-mode-map
(let ((map (make-sparse-keymap)))
;; `image-mode-map' has bindings that do not make sense in image-dired
;; (set-keymap-parent map image-mode-map)
(define-key map "f" 'image-dired-display-current-image-full)
(define-key map "s" 'image-dired-display-current-image-sized)
(define-key map "g" nil)
;; Useful bindings from `image-mode-map'
(define-key map [remap forward-char] 'image-forward-hscroll)
(define-key map [remap backward-char] 'image-backward-hscroll)
...
It seems I knew about `image-mode' but perhaps it never crossed my mind
to inherit from it. 16 years later, my memory fails me...
At any rate I have nothing against it, if someone wants to give it a try.

Thank you, that is useful information. I intend to look into this.

I fixed this in `image-dired' (see separate patch).
I guess we could rebase thumbs.el to also use the built-in image viewing
support, but I took a look and this external conversion seems built into
the foundation of how that library works. So this looks to me like it
would amount to a rewrite of thumbs.el. I could be wrong of course, but
that was my conclusion after poking at it for an hour or so.
Furthermore, at this point, image-dired.el is by far the more powerful
package, and it seems better implemented overall. Although it borrows
heavily from thumbs.el (or at least it used to), thumbs.el seems fully
redundant these days. However, it has some features that image-dired.el
does not, especially when it comes to modifying images.
So rather than attempting a rewrite of thumbs.el, the better solution
seems to me to add any important missing features from thumbs.el to
image-dired.el, and then obsoleting the former (not necessarily in that
order, but either way is fine to me).

See the attached patch. Unsurprisingly, this makes `image-dired' feel
quite a bit snappier, as we avoid a lot of unnecessary work.

No comments within a week, so I've now pushed to master as commit
73a6c8f98f with some further tweaks and a NEWS entry.
Please report here or open a new bug if you run into any issues.

No further comments within 6 weeks, so I think we can say that this bug
is resolved for now, and we can look into making thumbs.el obsolete
later.
I'm therefore closing this bug as fixed for image-dired.el. If that
conclusion is incorrect, please re-open.
