API Reference > imodeljs-common > Symbology Symbology Types that define the appearance of geometry. Classes Name Description ColorDef An immutable integer representation of a color. FontMap A FontMap holds the table of known fonts available in an iModel. GeometryParams Describes the display properties of graphics in a persistent element's GeometryStream that aren't inherited from SubCategoryAppearance. GraphicParams The "cooked" material and symbology for a RenderGraphic. HSLColor An immutable color defined by Hue, Saturation, and Lightness. HSVColor An immutable color defined by Hue, Saturation, and Value RgbColor An immutable representation of a color with red, green, and blue components each in the integer range [0, 255]. SubCategoryAppearance Parameters that define the way geometry on a SubCategory appears. ThematicDisplay The thematic display setup of a DisplayStyle3d. ThematicDisplaySensor A sensor in world space, used for ThematicDisplayMode.InverseDistanceWeightedSensors. ThematicDisplaySensorSettings Settings for sensor-based thematic display for ThematicDisplayMode.InverseDistanceWeightedSensors. ThematicGradientSettings Thematic settings specific to creating a color gradient used by ThematicDisplay. Constants Name Description ColorByName A set of known colors by HTML color name, as a 32-bit integer in the form 0xBBGGRR (red is the low byte). Enumerations Name Description BackgroundFill Describes how a view's background color affects the interior area of a closed region. FillDisplay Whether a closed region should be drawn for wireframe display with its internal area filled or not. FillFlags Flags indicating whether and how the interiors of closed planar regions is displayed within a view. FontType The type of a font. GeometryClass Categorizes a piece of geometry within a GeometryStream. HSVConstants LinePixels Enumerates the available patterns for drawing patterned lines. ThematicDisplayMode The thematic display mode. ThematicGradientColorScheme A color scheme used to generate the colors of a thematic gradient within an applied range. ThematicGradientMode A thematic gradient mode used to generate and apply a thematic effect to a scene. Interfaces Name Description FontMapProps The properties of a FontMap FontProps The properties of a Font. RgbColorProps JSON representation of an RgbColor, with each component an integer in the range [0, 255]. ThematicDisplayProps JSON representation of the thematic display setup of a DisplayStyle3d. ThematicDisplaySensorProps JSON representation of a ThematicDisplaySensor. ThematicDisplaySensorSettingsProps JSON representation of a ThematicDisplaySensorSettings for ThematicDisplayMode.InverseDistanceWeightedSensors. ThematicGradientSettingsProps JSON representation of a ThematicGradientSettings. Namespaces Name Description AreaPattern Gradient Namespace containing types for defining a color gradient, often used for filled planar regions. LineStyle SubCategoryAppearance Type Aliases Name Description ColorDefProps The JSON representation of a ColorDef - an unsigned 32-bit integer in 0xTTBBGGRR format. Last Updated: 12 June, 2024
