initialize

Initializes the PDF engine and the underlying WebAssembly library.

Signature


initialize(): PdfTask<boolean>;

Description

This method must be called once before any other engine methods can be used. It sets up the PDFium environment within the WebAssembly module, preparing it for document processing.

Attempting to call other methods like openDocumentUrl before initialize has completed will result in an error.

Parameters

This method takes no parameters.

Returns

PdfTask<boolean>

A Task that resolves with true once the engine has been successfully initialized and is ready for use.

See Concepts: Tasks for more on how to handle asynchronous operations.

Example


// Assuming 'engine' is a newly created WebWorkerEngine or PdfiumEngine instance
 
async function setupPdfProcessor() {
  try {
    const success = await engine.initialize().toPromise();
    if (success) {
      console.log('PDF engine is ready!');
      // You can now safely call other engine methods.
    }
  } catch (error) {
    console.error('Failed to initialize PDF engine:', error);
  }
}
 
setupPdfProcessor();
