Fill symbol layers are components of symbols
Fill symbol layers are components of symbols that cover areal geometries. They are most often used in polygon symbols. There are different types of fills:
Fills polygonal geometry with a single solid color.
Fills polygonal geometry with a uniform series of parallel line symbols.
Fills polygonal geometry with a color scheme. Only continuous color schemes are supported.
Fills polygonal geometry with an image file.
Fills polygonal or multipatch geometry with procedural symbology based on the properties exposed by a rule package.
Material fill applies color to 3D object features in mesh symbols.
Use the pull-down menu within each layer as they are listed in the Format Symbol mode of the Symbology pane, on the Properties tab. Click the Layers tab to set the layer type.
Solid fill symbol layers
Solid fill symbols contain only a single property, Color, which can be partially transparent.
Hatched fill symbol layers
Hatched fill symbol layers use an existing line symbol to draw a uniform series of parallel lines. in the Format Symbol mode of the Symbology pane, on the Properties tab, on the Layers tab , expand the Appearance group. Pick a preset line symbol from the Hatch line symbol pull-down gallery, or click More line symbols in that gallery to choose one from an available style.
You are only able to change the basic properties—Color and Line width—for the selected line symbol. These properties are also in the Appearance group. If you need a more detailed line, you can create one in your Favorites style or any other editable style.
You define the arrangement of the hatch lines using the properties in the Pattern group. Define the angle of the lines by choosing from the Angle pull-down menu or typing a custom value. The Separation property defines the distance between the line symbols. Adjust the Offset property only if it is necessary to customize where the drawing of the line symbols originates from relative to the polygon boundaries.
Gradient fill symbol layers
Gradient fill symbol layers use an existing color scheme to draw an arrangement of colors across the polygonal area. In the Format Symbol mode of the Symbology pane, on the Properties tab, on the Layers tab , expand the Appearance group. Pick a preset color scheme from the pull-down gallery, or click More color schemes in that gallery to choose one from an available style. Only continuous color schemes can be applied to gradient fill symbol layers.
You can reverse the direction of the color scheme, and if it is a simple two-color continuous color scheme, you can change the colors. If you need a more detailed color scheme than one in the available styles, you can create one in your Favorites style or any other editable style.
You define the arrangement of the gradient colors using the properties in the Pattern group. Define the direction of the gradient by choosing from the Direction pull-down menu: Linear, Rectangular, Circular, or Buffered. Define the gradient type as Discrete—unique bands of color—or Continuous—smooth transitions from one color to another—from the Type pull-down menu. The Interval property defines how many bands draw in the discrete case. The Extent and Size properties define how much of the feature is covered by the color scheme in an absolute distance or in a relative percentage.
Buffered gradients can only be of type discrete at the current release.
Picture fill symbol layers
Picture fill symbol layers use an image file to fill polygonal area. In the Format Symbol mode of the Symbology pane, on the Properties tab, on the Layers tab , expand the Appearance group. Click Picture to browse to an image file. Valid file formats are *.bmp, *.jpg, *.png, or *.gif. Adjust the Quality, Tint, and Size properties as necessary.
Set the Tint property to white, which is the default setting, to draw the image in its native colors. Setting this property to no color causes no image to be drawn at all.
Procedural fill symbol layers
Procedural fills draw only in a 3D context. They are ignored when the symbol is used in 2D. Their symbol properties are dictated by a source rule package (.rpk file). Rule packages are created in Esri CityEngine. If the fill layer is used in a polygon, point, or line symbol, the @StartRule of the rule package must specify @InPoly annotation. If the fill layer is used in a mesh symbol, the @StartRule must specify @InMesh annotation, so it can be applied to multipatch geometry.
Material fill symbol layers
Material fills are only available in mesh symbols that are applied to 3D object features. The color applied to the object is based on the selected material mode:
|Material mode type|
The RGB values of the object are multiplied by the RGB values of the selected color. This is generally the best choice when the object is white, or nearly white.
The hue and saturation components of the selected color replace those of the object. The value components of the selected color and the object color are multiplied together to obtain the final value component. This is generally the best choice when you want to overlay color to an already colored object.
The texture and color of the object are fully replaced by the selected color.
