Declaration
property RulerUnits: TIEUnits;
Description
Specifies the units when a
RulerMode is specified.
Note:
◼Use
MeasureDecimalPlaces to specify the number of decimal places
◼Unit text can be edited with
MeasureUnits◼Use
TImageEnView.SetScale to adjust the scale of units
Default: Specified by
DefaultMeasureUnit (Defaults to ieuPixels)
// Set ruler units to MM
ImageEnView1.CurrentLayer.RulerUnits := ieuMillimeters;
// Add a ruler layer showing lengths in CM (to one decimal place)
