Interface IPercentage
Namespace: IronPPT.Interfaces
Assembly: IronPPT.dll
Syntax
public interface IPercentageIPercentage is the value a developer reads or sets when a slide property is expressed as a proportion rather than an absolute measurement, the kind of figure used for a color saturation, a scale factor, or a relative width. Wrapping the number in a contract rather than passing a bare double keeps proportion values distinct from point or pixel measurements, so a property typed as IPercentage cannot be confused with one typed as a unit. Lean on the FAQ to place it against IDocUnit, the absolute-measurement contract it sits beside.
A developer usually receives an IPercentage from the property that exposes it rather than constructing one. The concrete implementor in IronPPT is Percentage, and the contract carries a single nullable Value of type double so an unset proportion reads as null instead of zero. ToString renders the value for display or logging. Reading Value gives the current proportion; assigning it changes the proportion the consuming property applies.
IPercentage saturation = new Percentage();
saturation.Value = 75.0;The paragraph style example and the add shape example show properties that take proportional values.
