The FilterBrightness property in the Sandbox.UI.BaseStyles class represents the filter-brightness CSS property. This property is used to adjust the brightness of an element's content. The value is of type System.Nullable<Sandbox.UI.Length>, allowing you to specify a length value or leave it unset.
To use the FilterBrightness property, you can set it to a specific Length value to adjust the brightness of an element. A higher value increases brightness, while a lower value decreases it. If the property is set to null, the default brightness is applied.
// Example of setting the FilterBrightness property var styles = new BaseStyles(); styles.FilterBrightness = new Length(1.5f); // Increase brightness by 50% // Resetting to default styles.FilterBrightness = null;
