Problem to convert .heic image format file as an input

Failure

I tried some versions on imagemagick, but the default installed version seems not support .HEIC format. I need to convert HEIC to jpeg format for my pictures taken by iphone.

Even a version of downloaded portable package of magick is ImageMagick7, I could not convert .heic file as a input image.

Solution

As per a blog (ref. How to insatll iomageMagick 7 on Ubuntu about the same problem as above, I built and add libraries for converting .heic files as below.

1. Edit sources

Edit /etc/apt/sources.list and add deb(archive contains binary packages) and deb-src(source packages) at the bottom of the file.

/etc/apt/sources.list 

1
2

4
# deb-src http://security.ubuntu.com/ubuntu bionic-security multiverse

deb http://us.archive.ubuntu.com/ubuntu/ xenial main restricted
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial main restricted

Then update apt. 

1
$ sudo apt-get update

2. Build ImageMagick dependencies

Make sure all of ImageMagick dependencies are installed. 

1
$  sudo apt-get build-dep imagemagick -y

3. Add and install ppa for the libheif and libde265 packages that are required for ImageMagick 7

Add required the other libraries(libheif and libde265) as PPAs to repositories and install them to support heic files.

5
$ sudo add-apt-repository ppa:strukturag/libheif
$ sudo add-apt-repository ppa:strukturag/libde265
$ sudo apt-get update
$ sudo apt-get install libheif-dev
$ sudo apt-get install libde265-dev

4. Downlaod, configure, and install ImageMagick7

Download and install ImageMagick7.cd into /opt, do configuration as with-heic=yes and install. The version of ImageMagick-7.0.11-0 is the latest one as of 16 Feb 2021.

$ cd /opt
$ sudo wget https://www.imagemagick.org/download/ImageMagick-7.0.11-0.tar.gz
$ sudo tar xvzf ImageMagick-7.0.11-0.tar.gz
$ cd ImageMagick-7.0.11-0
$ sudo ./configure --with-heic=yes
$ sudo make
$ sudo make install   # $ `sudo checkinstall` may work here if you have that.     
$ sudo ldconfig /usr/local/lib # this creates the necessary links and cache to the most recent shared libraries in /usr/local/lib

Then you reopen terminal, you should have:

# magic --version has the same output above

Success

Finally, imagemagick on ubuntu supported .heic files.

$ convert ubuntu-install1.heic ubuntu-install1.jpg
