The NoSuchMethodError you’re encountering, specifically for int com.aspose.pdf.Page.getRotate, indicates a version mismatch between the Aspose libraries in your project. This error suggests that the method you’re trying to call does not exist in the version of the Aspose.PDF library currently included.

Cause: The error is likely due to using incompatible versions of Aspose.OCR and Aspose.PDF, or an outdated version of Aspose.PDF that does not support the method you are trying to use.

Solution: To resolve this issue, follow these steps:

  1. Check Library Versions: Verify that you are using compatible versions of Aspose.OCR and Aspose.PDF. Refer to the release notes or documentation for any breaking changes or method deprecations.

  2. Update Libraries: If your Aspose.PDF library is outdated, update it to the latest version. You can download the latest version from the Aspose website or use a package manager.

  3. Clean and Rebuild: After updating, clean your project and rebuild it to ensure all references are correctly updated.

  4. Check Dependencies: Ensure that all dependencies required by Aspose.OCR and Aspose.PDF are included and up to date.

  5. Review Sample Code: If you are using sample code, confirm that it is compatible with the versions of the libraries you are using, as sample code may reference methods not available in older versions.

Next Steps: If you follow these steps and still encounter issues, please provide the versions of the libraries you are using, and I will assist you further.

Also it appears to be correct in aspose-ocr-24.12.0 but not in 25.1.0. You can use the modern version of PDF
