My usecase -
- Use Dia (with some custom shapes) to draw a diagram.
- use Python plugin to generate some data based on the diagram.
- Export the diagram to PDF for review.
There are a few aspects of this simple usecase that can improve -
1. A shape's default size and attributes are not controllable.
They are typically too big to fit a substantial diagram on a page.
2. When exporting #1 requires all kinds of scaling to make the diagram
fit.
3. I've not managed to successfully position the exported image in
the center of the page.
