[Cuis-dev] Cuis-dev Digest, Vol 35, Issue 43

Thu Feb 17 07:23:39 PST 2022

David,

I just tested an image that uses a TrueType font and thus Vectorgrahics without
the VectorEnginePlugin on Linux. It hangs and produces a series of Cuis*Debug.log files,
like the one I attached. You may find a bunch of similar files in your image directory.
They may confirm my hypothesis.
Fixing this I have to leave to Juan.

The latest prerelease VM should include the plugin:
https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/tag/202112201228
I presume the issue will be gone once you use this VM
and thus the plugin.

Hoever there is one important point you may have missed:
Before you load the VectorGrahics package you should
install the latest changes into the image.
This can be triggered by selecting the following
menu item in the changes menu:
World->Changes->Install new updates

HTH,
Gerald
