Hello!

Several of emacs image related features have stopped working properly:
* Eww does not render images showing empty squares instead.
* When visiting an image in a buffer and pressing n to visit the next
  image the next image is either not displayed at all (showing an empty
  square instead) or a thumbnail sized version is displayed.
* Transformations such as "Fit to Window Width" or "Rotate Image" do not
  work at all. The following error message is displayed instead:
  ImageMagick error: no decode delegate for this image format `PBM' @
  error/constitute.c/ReadImage/504
  (This happens with all image formats not just .pbm)

This is independent of any init file as it still happens if emacs is run
with the -Q flag.
Everything works as it should if I roll back to the version from
2017-09-22.

I am running GuixSD on an x86-64 machine with the following config:

;; This is an operating system configuration file
;; for a "desktop" setup with StumpWM and EXWM where
;; the root partition is encrypted with LUKS.

Indeed, I experience this with DocView as well (when resizing), which
leads to:

  ImageMagick error: no decode delegate for this image format `PNG' @ error/constitute.c/ReadImage/504

Could it be a CLI change in ImageMagick?  The package was upgraded in
87a9c53b7ca08bd490c94fe5579c3f26c19be78c.

Apparently this was a known bug in ImageMagick 6.9.9-15 (and 6.9.9-17)
(https://github.com/ImageMagick/ImageMagick/issues/825). It has been
fixed in version 6.9.9-18.

I believe the bug was introduced in
030030f4416b54285dcdd58bddb863c0e6bda4c4. It appears to be a known bug
in ImageMagick (https://github.com/ImageMagick/ImageMagick/issues/825),
which was already present in version 6.9.9-15.
It has been fixed in version 6.9.9-18
(https://github.com/ImageMagick/ImageMagick/blob/ImageMagick-6/ChangeLog).

Diego

Hello!  I just pushed an update to 6.9.9-18, can you verify that it
works?

Thanks for the report!

Hello!

I upgraded Emacs and everything works as expected.

Thanks for fixing it!
