Fonts not found by imagemagick or graphviz in versions 3.12.x and 3.11.x (docker images)
Dockerfile 3.11 :
FROM alpine:3.11
RUN apk fix && apk add --update graphviz font-bitstream-type1 ghostscript-fonts imagemagick6 && rm -rf /var/cache/apk/*
Dockerfile 3.12 :
FROM alpine:3.12
RUN apk fix && apk add --update graphviz font-bitstream-type1 ghostscript-fonts imagemagick6 && rm -rf /var/cache/apk/*
Making an image png, tiff or png directly with graphviz or through svg and convert by imagemagick has the same result : an image where the text is printed with symbols.
NB : Everything is OK in 3.10.x
