destroy

Shuts down the PDF engine and frees all global resources used by the WebAssembly library.

Signature


destroy(): PdfTask<boolean>;

Description

This method is the counterpart to initialize. It should be called when your application is completely finished with all PDF operations and the engine instance is no longer needed. Calling destroy ensures that all memory allocated by the PDFium library is released, preventing memory leaks in your application.

After destroy has been called, the engine instance cannot be used again.

Parameters

This method takes no parameters.

Returns

PdfTask<boolean>

A Task that resolves with true once the engine and its resources have been successfully cleaned up.

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

Example


// Assuming 'engine' is an initialized engine instance that is no longer needed
 
async function cleanupPdfProcessor() {
  try {
    await engine.destroy().toPromise();
    console.log('PDF engine has been shut down and resources are freed.');
  } catch (error) {
    console.error('Failed to destroy PDF engine:', error);
  }
}
 
// Call this when your component unmounts or your application closes.
cleanupPdfProcessor();
