Class Luminance
Namespace: IronPPT.Models
Assembly: IronPPT.dll
Syntax
public class Luminance : BaseColorField, ILuminance, IBaseColorFieldBrightness adjustment on a slide color runs through Luminance. It holds a single lightness amount, expressed as a percentage, that shifts a theme or scheme color lighter or darker without picking a brand-new color value. Reach for it when a shape, text, or fill should track a base color but sit a step brighter or dimmer than the original.
The amount lives in the Value property, an IPercentage, so a luminance of fifty percent reads as a half-bright variation of the source color. Because Luminance defines an implicit conversion from double, a plain numeric value assigns directly where a Luminance is expected, which keeps color-tweak code short. Luminance derives from BaseColorField and sits alongside Hue and Saturation as the three color-component adjustments IronPPT exposes, so a color is tuned one axis at a time rather than recomputed by hand.
Luminance luminance = 0.5;The add shape example creates the shapes whose color these adjustments tune, and the manage image how-to works with visual content on a slide.
