Hello,

Thank you for your inquiry.
I have analyzed the PDF document you provided and found that it consists of scanned images rather than editable text content. The text extraction functionality in Spire.PDF is specifically designed for text-based PDFs and cannot recognize text from images, which is why no text results were returned.
Spire.OCR provides the functionality to extract text from images. You can first convert your PDF file to images and then use Spire.OCR to perform text recognition and extraction. For specific usage methods, please refer to the following tutorials:

Please don't hesitate to let us know if you have any questions or need further assistance.
