Constructors

constructor

new DxfEntityProcessor(sourceSR, targetSR, contextOverrides?): DxfEntityProcessor
Initializes a new instance of the DxfEntityProcessor.
Parameters
- sourceSR: SpatialReference
  The source spatial reference of the DXF data.
- targetSR: SpatialReference
  The target spatial reference for the output layers.
- contextOverrides: Partial<IDxfJsonComponentContext> = {}
  Optional partial context to override default values.
Returns DxfEntityProcessor

Methods

convertToSpatialReference

convertToSpatialReference(x, y): Promise<[number, number]>
Converts a single coordinate pair from the source spatial reference to the target spatial reference.
Parameters
- x: number
  The x-coordinate to convert.
- y: number
  The y-coordinate to convert.
Returns Promise<[number, number]>
A promise that resolves with the converted [x, y] coordinates.

getContext

getContext(): IDxfJsonComponentContext
Returns the fully constructed DXF conversion context.

Returns IDxfJsonComponentContext
The shared DXF conversion context.

process

process(entity): Promise<void>
Processes a single DXF entity or an array of entities. It filters out "BLOCK" and "ENDBLK" types and dispatches the rest to the appropriate handler.
Parameters
- entity: IEntity | IEntity[]
  The entity or array of entities to process.
Returns Promise<void>

processAll

processAll(): Promise<(FeatureLayer | GeoJSONLayer | GraphicsLayer)[]>
Processes all entities from the DXF data in batches to keep the UI responsive.

Returns Promise<(FeatureLayer | GeoJSONLayer | GraphicsLayer)[]>
A promise that resolves with an array of the generated layers.

projectMany

projectMany(points): Promise<[number, number][]>
Project an array of points into the target spatial reference.
Parameters
- points: Point[]
  Array of points to project.
Returns Promise<[number, number][]>
Array of converted coordinate pairs.
