<r>

Activate Ruler mode (resolution depends on current ZF/user config).
The features status-bar caption will be lit with ‘R’ when ruler mode is active.

<R>

Open the Ruler Config dialog window which remains resident until closed. You can
either use Screen Pixels or Image pixels and set the spacing per axis.
The Screen Pixels means that the ruler bars will be indented by the display logic
pixels no matter the zoom factor.
The Image Pixels means that the ruler bars will be indented by the viewed image
pixels so if one selects 20 (x/y) then a ruler bar will be set at 0, 20, 40, …
For Image Pixels mode, you can also set a starting offset per axis to start the ruler
from which enables aligning data that start at <0,0>.
Use “Apply changes” button to test your changes.
