Relevant Dockerfile part:

FROM registry.var-lab.com/php/php:7.4.20-fpm-alpine

...

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-3.5.1 \
    && docker-php-ext-enable imagick \
    && apk add --no-cache --virtual .imagick-runtime-deps imagemagick \
    && apk del .phpize-deps

It has worked without using docker, but with the same PHP version "directy" installed on an Ubuntu 16.x machine.

Hi, can you try:

i. List the fonts returned by Imagick::queryFonts() to see if there any fonts configured.

ii. Explicitly set a font, either one listed from above, or a TTF file you acquire from somewhere.

This error message (which is not great) seems to happen when a default font isn't available.

[4d4ch4u32]

Thanks for your reply @Danack. Can you say which one the default font is?

[4d4ch4u32]

Imagick::queryFonts() outputs an empty array.

It works now, after adding the following line to the Dockerfile:

RUN apk add --no-cache msttcorefonts-installer && update-ms-fonts && fc-cache -f

[Danack]

I think either Arial or Helvetica.

I'm beginning to think though that relying on system fonts is a 'not great' way of managing fonts, and explicitly packaging the fonts you want to use might be better.

[4d4ch4u32]

At least a more descriptive error message would be very helpful!

[Danack]

Going to change this back to open so people see it, and remind myself to do something about it.

Explicitly set a font, either one listed from above, or a TTF file you acquire from somewhere. How do I do this?

I have a TTF font and don't want to install the entire msttcorefonts-installer

Using Wand, Python and Docker.
