RenderinstructionPolyline class

Rendering instruction for polylines (open paths) on the map.

This class handles the rendering of linear features such as roads, paths, rivers, boundaries, and other line-based map elements. It supports stroke styling, bitmap patterns, and various line cap and join styles.

Key features:

  • Stroke styling with customizable width, color, and patterns
  • Bitmap pattern fills along the line path
  • Line cap styles (round, square, butt)
  • Line join styles (round, bevel, miter)
  • Zoom level dependent scaling and visibility

Constructors

RenderinstructionPolyline(int level)
Creates a new polyline 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?
Optional identifier for this polyline instruction.

level int

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.

runtimeType Type
A representation of the runtime type of the object.

Creates a zoom level specific copy of this polyline instruction.

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
isStrokeTransparent() bool
inherited
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 polyline 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.
