Every text field in PhotoLine shows values in pixel. But I want other units like inches.
You can change the units of every size field and of the rulers in PhotoLine (see also chapter 3.3.7). Right-click (on Windows) or Ctrl-click (on Mac OS) on the field and you will get a popup with the selectable units. You can do this also with the font size, but on Windows you have to right-click on the arrow beside the value.
