Mail MergePDF단어 변환 방법

이 문서에서는PDF에서 변환 한 다음PDF저장 한 단어 문서에서Mail Merge하는 방법을 보여주는 간단한 예를 보여줍니다. Aspose.Words을 사용하여PDF에서 단어 변환 파일에 대한 간단한Mail Merge프로세스를 실행하는 것은 경우에 따라 작동하지 않습니다. PDF을DOCX(워드 문서)로 변환하는 동안Aspose.PDF이 실제MERGEFIELDs를 쓰지 않기 때문에 문제가 발생합니다. 그러나 이러한 정적 텍스트를 실제MERGEFIELDs로 변환 한 다음Mail Merge작업을 실행하여 달성 할 수 있습니다. 다음 해결 방법을 참조하십시오.
