This is a measure tool that allows measuring distances (in units selected in Preferences), azimuths in degrees (cw from north) and area (in km2). Start by a left clicking and proceed with as many left clicks as you want. A double-left click adds the last point and shows up the results. Right clicks remove the previously entered point. The Area per color option displays the area occupied by each image intensity value in a table. This works only on indexed images since for RGB images there are just too many colors to perform this computation. The same information displayed in the table is also saved the sub-directory tmp of the Mirones installation dir, under the name of: area_per_color.dat.
