If verticalMode is true, it indicates vertical scrolling; otherwise, it's horizontal scrolling.

    verticalMode: true
  }

ComPDFKit.openDocument(_document, '', config);

  }
});
ComPDFKit.openDocument(_document, '', config);

The scrolling mode can be set to continuous scrolling or page flipping mode. When continueMode is true, it represents continuous scrolling; otherwise, it's page flipping scrolling.

  readerViewConfig: {
    continueMode: true
  }
});
ComPDFKit.openDocument(_document, '', config);

ComPDFKit.openDocument(_document, '', config);
