Class AcDbDxfConverter

Default database converter for DXF files.

This class extends AcDbDatabaseConverter to provide specialized functionality for converting DXF (Drawing Exchange Format) files into AcDbDatabase objects. It handles parsing DXF data, processing entities, blocks, tables, and other DXF-specific structures.

Example

const converter = new AcDbDxfConverter();
const database = await converter.convert(dxfData);

Methods

`Protected`getFonts

getFonts(dxf: ParsedDxf): string[]
Gets all fonts used by entities in model space and paper space.

This method analyzes the DXF data to extract all font names used by text entities, MText entities, and insert entities throughout the drawing.
Parameters

  Input parsed DXF model
Returns string[]
Array of font names used in the drawing
Example
```
const fonts = converter.getFonts(parsedDxf);
console.log('Used fonts:', fonts);

    minimumChunkSize: number,
    startPercentage: { value: number },
    progress?: AcDbConversionProgressCallback,
): Promise<void>
Processes entities in batches to maintain UI responsiveness.

This method breaks up the entity processing 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
- dxf: ParsedDxf
  Parsed DXF data
- db: AcDbDatabase
  Target database to add entities to
- minimumChunkSize: number
  Minimum number of entities to process in each chunk
- startPercentage: { value: number }
  Object containing the starting percentage for progress tracking
- Optionalprogress: AcDbConversionProgressCallback
  Optional callback for progress updates
Returns Promise<void>
Example
```
await converter.processEntities(dxf, database, 100, { value: 0 }, progressCallback);
```
Overrides AcDbDatabaseConverter.processEntities
- Defined in data-model/src/converter/AcDbDxfConverter.ts:182

`Protected`processHeader

processHeader(model: ParsedDxf, db: AcDbDatabase): void
Processes header variables from the DXF file.

This method extracts and sets various header variables such as color settings, angle base, angle direction, units, and point display settings.
Parameters
- model: ParsedDxf
  Parsed DXF model containing header information
- db: AcDbDatabase
  Target database to set header variables on
