Hello,

When having a simple dia file with a basic ellipse (see attached file)
then exporting to PNG, the resulting ellipse is rendered *without*
antialiasing which is not very beautiful.

Thanks for your report. I managed to reproduce the problem, dug into the
source code and found a way to improve the situation. I forwarded the
issue upstream: https://gitlab.gnome.org/GNOME/dia/-/issues/566.



According to Dia FAQ[1], it's possible to have antialiasing. Some people
even mention[2] an antialias exporter which I can't find in Dia from
Debian.

too-small

These links are quite old. Link [1] mentions libart for antialiasing
support, yet libart dependency was removed since
(https://gitlab.gnome.org/GNOME/dia/-/commit/665f9429dc7ad9a27cc6c0c265e586f37a5db33a).
