Imagemagick lacks support for webp

[Janghou]

On https://developers.google.com/speed/webp/docs/using is stated that ImageMagick does support webp

The Ubuntu source package for imagemagick does not declare a build dependency on libwebp-dev. Thus imagemagick gets build without webp support.

I consider this a bug and suggest that ImageMagick should be build with webp support

12.04 LTS

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

As the debian mainteners, I refuse to add webp support as is.

in six month we found 5 security bugs in webp support.

Please let the time to stabilize

@ broucaries

But does that mean, there is no way to convert webp images to/from other format at the moment on Debian/Ubuntu or are there any tools to do conversions available in some other package?

[Dimitri John Ledkov (xnox)]

In the mean time one can install:

$ sudo apt-get install webp

And use dwebp and cwebp commands to decompress/compress from/to webp file format.

it's 03/24/2015, almost 2 years after the "Please let the time to stabilize" answer. It's needed more time?

Some Google-affiliated researchers have fuzzed WebP in ImageMagick and found no significant bugs thus far. I would say that WebP support is more stable at this time. Please build it as default option.

Even PHP has webp support since 5.5

Just encountered the problem in Xenial.

[Kyle Tse (shtse8)]

Please support webp no matter there is a bug or not. That should not our concern.

I would love to have webp support in imagemagick.

[ipatrol (ipatrol6010)]

According to https://askubuntu.com/a/788917 WebP support works in 16.04 and up as long as the webp package is installed. Only thing to do then would perhaps be to make it a recommends/suggests of the imagemagick package?

[Michael Bolli (michael-bolli-us)]

In 18.04 LTS (bionic), "convert -list format" does not list webp.
libwebp-dev, libwebp6 and webp packages are installed.
Can this please be doublechecked?
