RenderinstructionCircle class
Rendering instruction for circular shapes on the map.
This class handles the rendering of circular elements such as POI markers, circular area highlights, or decorative elements. Circles can have both fill colors and stroke outlines with configurable radius and positioning.
Key features:
- Configurable radius with optional zoom-level scaling
- Fill colors and stroke outlines
- Positioning relative to anchor points
- Zoom-dependent size scaling for better visibility

Constructors
- RenderinstructionCircle(int level)
- Creates a new circle rendering instruction for the specified drawing level.
Properties
- boundary ↔ MapRectangle?
-
The boundary of this object in pixels relative to the center of the
corresponding node or way. This is a cache and will be calculated by asking.
Do NOT clone this.
getter/setter pairinherited
- display ↔ MapDisplay
-
Display mode controlling when this instruction should be rendered.
getter/setter pairinherited
- dy ↔ double
-
getter/setter pairinherited
- fillColor ↔ int
-
For texts the fillColor is the inner color, whereas the strokeColor is the surrounding "frame" of the text
getter/setter pairinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- level ↔ int
-
latefinalinherited
- position ↔ MapPositioning
-
Positioning of the circle relative to its anchor point.
getter/setter pair
- priority ↔ int
-
getter/setter pairinherited
- radius ↔ double
-
The radius of the circle in pixels.
getter/setter pair
- rotateWithMap ↔ bool
-
if false (default) the symbol will always drawn in the same direction regardless of the map rotation. For example an exclamation symbol (!) will
always have the dot points towards the bottom of the screen.
If true the symbol rotates with the map.
getter/setter pairinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

- scale ↔ Scale
-
getter/setter pairinherited
- scaleRadius ↔ bool
-
Whether the radius should scale with zoom level changes.

-
forZoomlevel(
int zoomlevel, int level) → RenderinstructionCircle -
Creates a zoom level specific copy of this circle instruction.
override
-
getBoundary(
RenderInfo< Renderinstruction> renderInfo) → MapRectangle -
Returns the boundary of this object around the center of the area or the poi. If the boundary cannot determined exactly we need to estimate it.
This method is used only if the renderinstruction adds itself to label or clash (see LayerContainer)
override
-
getType(
) → String -
Returns the type identifier for this rendering instruction.

-
matchNode(
LayerContainer layerContainer, NodeProperties nodeProperties) → void -
Checks the nodeProperties and adds itself to the layerContainer if there is something to draw.
override
-
matchWay(
LayerContainer layerContainer, WayProperties wayProperties) → void -
Checks the wayProperties and adds itself to the layerContainer if there is something to draw.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
parse(
XmlElement rootElement) → void -
renderinstructionScale(
Renderinstruction base, int zoomlevel) → void -
Scales rendering parameters based on zoom level and base instruction.
inherited
-
secondPass(
SymbolSearcher symbolSearcher) → void -
Captions needs to find their assigned symbol to correctly render themself around the symbol. After all rules has been created a second pass is
executed where captions are able to find their assigned symbol.
