소스내용.txt

 

iTextSharp.zip

 

 

nuget 에서 iTextSharp 검색해여 "iTextSharp" 를 설치하면 iTextSharp 이 참조됩니다.

 

참고로 4.1.6 버전까지는 상용제품에 포함하는데 문제는 없습니다.

이를 설치하기 위에 nuget 의 command 에 실행합니다. 어려우시면 iTextSharp.zip 파일을 다운로드 받으세요.

 

 

Install-Package iTextSharp-LGPL

using iTextSharp.text;
using iTextSharp.text.pdf;

    ConvertJPG2PDF(jpgfile, pdf);

    return View();
}
