Hi,
I'm voting in support of Daniel's final proposal: the linear measurement tool.
Interpreting PDF's of maps, graphs, plans &c. often benefits from being able to
extract scaled dimensions.
I propose that such a click-and-drag tool context menu would allow it to be
'calibrated'  with some training values (from the graph or map axes, or plan
scale bars, for instance) - and then remain true as the PDF is zoomed in/out.
Context menu would allow user to select linear/area/angular dimension options.
A further context menu feature would allow the measured value to be inserted as
an annotation.

C'mon, it would be a beauty, don't you think?

As an example, look at the 'measure line/area/bearing/angle' tool in QGIS

thanks for listening - best wishes - JS
