How to install ImageMagick 7 on Ubuntu | Scottie’s Tech.Info

not worked

Step 1: Uninstall your old ImageMagick by doing:

apt remove imagemagick imagemagick-6-common

Step 2: Just in case, install all the build dependencies for ImageMagick:

apt build-dep imagemagick

Step 3: Install image libraries, including WEBP:

apt-get install checkinstall libwebp-dev libopenjp2-7-dev librsvg2-dev libde265-dev

Step 4: Install ImageMagick (latest) from source:

wget [https://www.imagemagick.org/download/ImageMagick.tar.gz](https://www.imagemagick.org/download/ImageMagick.tar.gz)

tar xzvf ImageMagick.tar.gz

cd to the extracted directory, and then run:

./configure --enable-shared --with-modules --with-gslib

make

make install

ldconfig /usr/local/lib

identify -version

Ta-DA!!! You’re done!
