Just for the record I want to flag the following.
A few months ago, on MSYS2-MinGW64, there was the upgrade from
ImageMagick 6.x to version 7.x. After this, 'configure' stopped to add
support for ImageMagick when building Emacs:
Does Emacs use imagemagick? no
(with version 6.x it is 'yes').
This seems related to the fact that ImageMagick people has changed many
file name, adding 'Magick' ahead. For example, 'configure' search for
Wand.pc but there is MagickWand.pc etc. As consequence, also image.c
seems broken related to ImageMagick-7.
I think this will regard also other systems when they will upgrade to
ImageMagick-7, unless that people will revert the naming convention.
Ciao,
Angelo.

I wonder what the plans are wrt ImageMagick-7.
Thank you!

Attached is a diff file for Emacs-25 and ImageMagick-7 in case it can help
(and provided I did no mistake).

Please rebase on master (Emacs 26), as it's too late for the release
branch.

I have adapted Fabrice patches (attached) to master and with it I have
built Emacs master last night (r128068.55b5265) on MSYS2/MINGW64 (with
the PKGBUILD for mingw-w64-emacs-git). I do not know if I did all OK and
have not tested every thing.
For example, now when I visit a PNG buffer, it fits window width by
default. If I do (on menu bar) Image - Fit to Window Height, it fits but
there is a BELL sound and this message on minibuffer:
Assertion failed: (= (cdr size) (- (nth 3 (window-inside-pixel-edges))
(nth 1 (window-inside-pixel-edges)))), 821, 814
user-error: Minibuffer window is not active
I tried with a few JPG files and they didn't display. In the minibuffer:
Cannot display image: ((= (cdr size) (- (nth 3
(window-inside-pixel-edges)) (nth 1 (window-inside-pixel-edges)))) 821 814)
After a while I retried with the same PNG file (which before was
displayed) but now it was not. Same "Cannot display..."
I wonder if this is to be expected or if it is a consequence of the
patches...
Ciao,
Angelo.

OK, now I have some more news.
Start Emacs and visit a PNG or JPG etc, file. For example foo-01.png. It
is displayed correctly and fitted to the windows *width*. Now do the
same with another graphical file. For example foo-02.png. It also is
displayed correctly and fitted to the window WIDTH.
Close foo-02.png and for foo-01.png click Image - Fit to Window Height.
It complains with a BELL sound and with the message:
>
> Assertion failed: (= (cdr size) (- (nth 3 (window-inside-pixel-edges))
> (nth 1 (window-inside-pixel-edges)))), 821, 814
> user-error: Minibuffer window is not active
but the file is displayed correctly, at least in appearance! If now one
re-visit foo-02.png it is visited in Fundamental mode and with the message:
> Cannot display image: ((= (cdr size) (- (nth 3
> (window-inside-pixel-edges)) (nth 1 (window-inside-pixel-edges)))) 821 814)
It seems that this build of Emacs does not like "Image - Fit to Window
Height". The graphical format (PNJ, JPG..) seems irrelevant..
I did the same steps with my build on GNU/Linux Mint 18.1, on which
there is installed ImageMagick-6 not -7. On this system all works as
expected without errors/issues...

Hi Angelo,

Hmm.. as I wrote the master build I did a few days ago on GNU/Linux Mint
18.1 with ImageMagick-6 does not show these issues.. They seem related
to ImageMagick-7 and/or MSYS2/MinGW64 builds..
