NoDecodeDelegateForThisImageFormat `JPEG' @ error/constitute.c/ReadImage/50

[tudor2004]

Can anybody help with the following error?

NoDecodeDelegateForThisImageFormat `JPEG' @ error/constitute.c/ReadImage/50

I'm not sure what kind of library I'm missing, this is my docker file

That's an imagick error. You need to make sure you have the proper "delegates" built in. Open up a command line and type convert -version and make sure jpeg is listed.

@cdowdy convert -version says sh: convert: not found, also tried magic convert -version

[cdowdy]

it's an imagick/docker error not a glide one. Either imagick isn't installed, isn't installed properly, cannot be found by php, not enabled or you can't be found in the path.

Did a quick Google for you and this may help
docker-library/php#105

ok, I ended up using another base image for PHP that is not based on alpine. the rest of the dockerfile logic remained the same

For others who googled themselves here, I was having the exact same problem (well, different line number in the error). My Dockerfile was pretty much identical with anything related to imagick.

My problem was that I was missing imagemagick itself. After adding apk add for imagemagick, problem was fixed and php -r 'print_r(Imagick::queryFormats());' list was no longer empty, it had 227 values including JPEG etc.

Using alpine image docker i just added this to my image and rebuild docker image.

RUN set -ex \ 
&& apk add --no-cache --virtual .phpize-deps $PHPIZE_DEPS imagemagick-dev libtool \
&& export CFLAGS="$PHP_CFLAGS" CPPFLAGS="$PHP_CPPFLAGS" LDFLAGS="$PHP_LDFLAGS" \ 
&& pecl install imagick-3.4.3 \
&& docker-php-ext-enable imagick \ && apk add --no-cache --virtual .imagick-runtime-deps imagemagick \ 
&& apk del .phpize-deps

@julitroalves just wanted to let you know: your lines saved my problem 👍

❓ a question to all: I use https://github.com/docker-slim/docker-slim to tiny my PHP image. the fantastic thing is: the size shrinks from 500MB to 100MB BUT that´s only because a lot of things gets deleted.
the base-image shows me every image format Imagick::queryFormats() : but the tiny image doesn´t show anything, so I am sure, there are some files somewhere, that must not be deleted. does anybody has an idea where these files are ? because docker-slim supports the --include-path option, to keep some folders (or files) from seeing deleted. thanks for any help!!

UPDATE: in case someone is interested, here´s my call to slim an alpine docker image and keep imagemagick working (that does not mean everything else is working 😏 ):

docker run --rm -v /docker/images/php/7.4:/app -w /app -v /var/run/docker.sock:/var/run/docker.sock dslim/docker-slim:latest build --dockerfile Dockerfile --include-exe --include-shell --include-path /etc/ImageMagick-7 --include-path /usr/share/ImageMagick-7 --include-path /usr/lib/ImageMagick-7.0.10 --include-path /etc/ssl/ --include-path /etc/fonts/ --include-path /usr/local/bin/ --include-path /usr/lib/libjpeg.so.8 --include-path /usr/lib//usr/lib/libjpeg.so.8.2.2 --include-path /usr/lib/libjpeg.so --include-path /usr/lib/libturbojpeg.so.0 --include-path /usr/lib/libjpeg.so.8.2.2 --include-path /usr/lib/libturbojpeg.so --include-path /usr/lib/libturbojpeg.so.0.2.0 --tag php:7.4-fpm.slim .

Closing as the issue seems to be resolved and isn't directly related Glide's code.
