Configuration for the converter

`Optional`progress

progress?: AcDbConversionProgressCallback

Optional progress callback for tracking conversion progress

Methods

`Protected`getFonts

getFonts(dwg: DwgDatabase): string[]
Gets all of fonts used by entities in model space and paper space
Parameters
- dwg: DwgDatabase
  dwg database model
Returns string[]
Returns all of fonts used by entities in model space and paper space
Overrides AcDbDatabaseConverter.getFonts
- Defined in libredwg-converter/src/AcDbLibreDwgConverter.ts:94

`Protected`getParserWorkerTimeout

getParserWorkerTimeout(data: ArrayBuffer, timeout?: number): number
Resolves the parser worker timeout in milliseconds.

Explicit timeout always takes precedence. Otherwise the timeout scales linearly with file size at one extra second per MiB, clamped to the range of 30 seconds to 2 minutes.
Parameters
- data: ArrayBuffer
- Optionaltimeout: number
Returns number
Inherited from AcDbDatabaseConverter.getParserWorkerTimeout
- Defined in data-model/lib/database/AcDbDatabaseConverter.d.ts:292

`Protected`onError

onError(error: AcCmTaskError): boolean
Parameters
- error: AcCmTaskError
Returns boolean
Inherited from AcDbDatabaseConverter.onError
- Defined in data-model/lib/database/AcDbDatabaseConverter.d.ts:283

`Protected`onFinished

onFinished(): void
Returns void
Inherited from AcDbDatabaseConverter.onFinished
- Defined in data-model/lib/database/AcDbDatabaseConverter.d.ts:284

`Protected`parse

parse(
data: ArrayBuffer,
timeout?: number,
): Promise<AcDbParsingTaskResult<DwgDatabase>>
Parameters
- data: ArrayBuffer
- Optionaltimeout: number
Returns Promise<AcDbParsingTaskResult<DwgDatabase>>
Overrides AcDbDatabaseConverter.parse

- Defined in libredwg-converter/src/AcDbLibreDwgConverter.ts:409

`Protected`processBlockTables

processBlockTables(model: DwgDatabase, db: AcDbDatabase): void
Parameters
- model: DwgDatabase
- db: AcDbDatabase
Returns void

    model: DwgDatabase,
    db: AcDbDatabase,
    minimumChunkSize: number,
    startPercentage: { value: number },
    progress?: AcDbConversionProgressCallback,
): Promise<void>
Breaks up the work into smaller chunks that are executed asynchronously. This is often referred to as "batch processing" or "cooperative multitasking," where the time-consuming task is broken into smaller pieces and executed in small intervals to allow the UI to remain responsive.
Parameters
- model: DwgDatabase
- db: AcDbDatabase
- minimumChunkSize: number
- startPercentage: { value: number }
- Optionalprogress: AcDbConversionProgressCallback
Returns Promise<void>

`Protected`processHeader

processHeader(model: DwgDatabase, db: AcDbDatabase): void
Parameters
- model: DwgDatabase
- db: AcDbDatabase
Returns void
Overrides AcDbDatabaseConverter.processHeader

`Protected`processLayers

processLayers(model: DwgDatabase, db: AcDbDatabase): void
Parameters
- model: DwgDatabase
- db: AcDbDatabase
Returns void
Overrides AcDbDatabaseConverter.processLayers
- Defined in libredwg-converter/src/AcDbLibreDwgConverter.ts:263

`Protected`processLineTypes

processLineTypes(model: DwgDatabase, db: AcDbDatabase): void

- db: AcDbDatabase
  The database to populate with converted data
- minimumChunkSize: number
  Minimum chunk size for batch processing
- Optionalprogress: AcDbConversionProgressCallback
  Optional progress callback
- Optionaltimeout: number
Returns Promise<void>
Promise that resolves when conversion is complete
