Use ImageMagick 7 instead of version 6

[ariaieboy]

Hello everyone, I use Imagick as my image driver to create AVIF format files.

Imagick works fine with AVIF files, but the V6 has a bug that turns transparent png files' backgrounds to black, which is fixed on V7.
Is there any way to upgrade Imagick to v7 when using this script.

Hi!
Are you using docker images? If so, which one?

[ariaieboy]

I use php:8.2-cli as base image

[mlocati]

The php:8.2 docker image is based (by default) on Debian 12 Bookworm.
Debian 12 provides by default ImageMagick 6.9.
If you want to use ImageMagick 7, you need to download, compile and install it manually. See https://www.google.com/search?q=install+imagemagick+7+debian for examples.

PS: imagick is the name of the PHP extension, ImageMagick is the name of the system library used by the imagick PHP extension.

I know that if I install imagick using, for example, https://github.com/SoftCreatR/imei
in my docker image and then install PHP imagick extension it will use the compiled version or the V6?

If you manually install imagemagick, you have to tell the apt system thay it must not install the imagemagick defauly system libraries.

You can do something like this:

#!/bin/bash

# Setup a sane environment
set -o errexit
set -o nounset

# Update apt packages
apt-get update

# Install apt package required by imei
apt-get install -qy cmake libltdl-dev nasm

# Compile imagemagick with imei
curl -sSL https://dist.1-2.dev/imei.sh -o - | bash -s

# Install apt package required to mark apt packages as already installed
apt-get install -qy equivs

# Mark apt packages as already installed
markPackageAsIntstalled() {
    # see https://unix.stackexchange.com/a/583756
    PKGNAME="$1"
    MPAI_TMP="$(mktemp -d)"
    cd "$MPAI_TMP"
    VERSION=99.99-99.99
    RELEASE="experimental; urgency=low\n\n  * Initial Release\n\n -- Dummy <dummy@example.com>  Thu,  31 Dec 2099 00:00:00 +0000\n"
    equivs-control ${PKGNAME}.ctl
    sed -i "s/^Package:.*/Package: ${PKGNAME}/" ${PKGNAME}.ctl
    sed -i "s/.*Changelog:.*/Changelog: dummychangelog/" ${PKGNAME}.ctl
    echo -e "${PKGNAME} (${VERSION}) ${RELEASE}"  > dummychangelog
    sed -i "s/^Version:.*/Version: ${VERSION}/" ${PKGNAME}.ctl
    equivs-build ${PKGNAME}.ctl 2>&1 >  ${PKGNAME}.ctl.log
    dpkg -i ${PKGNAME}*.deb
    cd - >/dev/null
    rm -rf cd "$MPAI_TMP"
    
}
