Cancel Conversion Task ​

ComPDF Conversion SDK supports interrupting an ongoing conversion task. Return true from isCancelled() to cancel the current task, or false to continue.

js
let cancelRequested = false;

const callback = {
  isCancelled() {
    return cancelRequested;
  }
};

The current addon calls JavaScript callbacks synchronously from the conversion call thread. If the native SDK triggers callbacks from internal worker threads in the future, the addon must use napi_threadsafe_function instead of direct napi_call_function().
