Properties

colorIndex

colorIndex: number

A running index to provide unique colors for entities.

dxf

dxf: IDxfData

Parsed DXF data structure.

dxfToFeatureLayerPolygonMapper

dxfToFeatureLayerPolygonMapper: DxfToFeatureLayerPolygonMapper

DxfContext responsible for polygon entity processing.

dxfToGeoJsonInsertBlockMapper

dxfToGeoJsonInsertBlockMapper: DxfToGeoJsonInsertBlockMapper

DxfContext responsible for insert block handling.

dxfToGeoJsonLineMapper

dxfToGeoJsonLineMapper: DxfToGeoJsonLineMapper

DxfContext responsible for line entity processing.

dxfToGeoJsonTextMapper

dxfToGeoJsonTextMapper: DxfToGeoJsonTextMapper

DxfContext responsible for text entity processing.

OptionalfileName

fileName?: string

The original file name of the DXF file.

OptionallastLineEnd

lastLineEnd?: [number, number]

The end coordinate of the last processed line or arc segment, used for determining continuity. It is undefined if there is no previous segment or if continuity is broken.

OptionallastLineLayer

lastLineLayer?: string

The layer of the last processed line or arc segment. This is used in conjunction with lastLineEnd to ensure that line segments are only merged if they belong to the same layer.

lineFeatures

lineFeatures: Feature<Geometry, {
    [name: string]: any;
}>[]

Generated GeoJSON line features.

mapSR

mapSR: SpatialReference

The spatial reference used for map display.

pointFeatures

pointFeatures: Feature<Geometry, {
    [name: string]: any;
}>[]

Generated GeoJSON point features.

polygonFeatures

polygonFeatures: Feature<Geometry, {
    [name: string]: any;
}>[]

Generated GeoJSON polygon features.

renderer_Object_Line

renderer_Object_Line: RendererObjectLine

Renderer for line features.

renderer_Object_Point

renderer_Object_Point: RendererObjectPoint

Renderer for point features.

renderer_Object_Polygon

renderer_Object_Polygon: RendererObjectPolygon

Renderer for polygon features.

OptionalsanitizedFileName

sanitizedFileName?: string

A sanitized version of the file name suitable for use in an ID.

sourceSR

sourceSR: SpatialReference

Source spatial reference.

subLayers

subLayers: (FeatureLayer | GeoJSONLayer | GraphicsLayer)[]

Generated sublayers (GeoJSON or graphics layers).

targetSR

targetSR: SpatialReference

Target spatial reference for transformation.

textFeatures

textFeatures: Feature<Geometry, {
    [name: string]: any;
}>[]

Generated GeoJSON text features.
