[Qgis-developer] Data-defined buttons for "en masse" size and rotation

[Vincent Mora]

Hi Regis,

Here is a PR for one element of this feature 
https://github.com/qgis/QGIS/pull/1853

It's only the ground work, so you have no GUI to help you setup the 
expression for the size & rotation, but you can use scale_exp and 
scale_linear to define your value range and the corresponding symbol 
size range. It works for line width too. The legend's symbol does 
dissapear though, but I believe it's due to the data defined size. I'll 
work on the legend to have something meaningful when using size expressions.

If you can recompile the branch and give feedback, it will be welcome.

Thanks,

V.
