RenderinstructionSymbol class
Rendering instruction for bitmap symbols and icons on the map.
This class handles the rendering of bitmap-based symbols such as POI icons, directional arrows, and other graphical elements. Symbols can be defined once with an ID and reused throughout the theme, supporting positioning, rotation, and scaling.
Key features:
- Reusable symbols with unique identifiers
- Bitmap scaling and positioning control
- Rotation support with optional map alignment
- Support for both node (POI) and way (area) symbols

- Implemented types
Constructors
- RenderinstructionSymbol(int level)
- Creates a new symbol rendering instruction for the specified drawing level.
Properties
- bitmapSrc ↔ String?
-
getter/setter pairinherited
- 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
- hashCode → int
-
The hash code for this object.
no setterinherited
- id ↔ String?
-
Unique identifier for this symbol, allowing reuse across the theme.
getter/setter pair
- level ↔ int
-
latefinalinherited
- positioning ↔ MapPositioning
-
Positioning of the symbol relative to its anchor point.
getter/setter pair
- priority ↔ int
-
getter/setter pairinherited
- 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.
no setterinherited
- scale ↔ Scale
-
getter/setter pairinherited
- serial → int
-
finalinherited
- theta ↔ double
-
Rotation angle of the symbol in radians.

-
forZoomlevel(
int zoomlevel, int level) → RenderinstructionSymbol -
Creates a zoom level specific copy of this symbol instruction.

getBitmapHeight(
) → int -

getBitmapWidth(
) → int -
inherited
-
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.
override
-
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 - Parses XML attributes to configure this symbol rendering instruction.
-
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.
