Jeff Smith 2023-09-25 : Below is an online demo using CloudTk. This demo runs “TCL ZINT with tk image output” in an Alpine Linux Docker container. It is a 27.9MB image which is made up of Alpine Linux + tclkit + zint.kit + libx11 + libxft + fontconfig + ttf-linux-libertine. It is run under a user account in the container. The container is restrictive with permissions for "Other" removed for "execute" and "read" for certain directories.
