pdf파일을 만드는 예제

import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;

public class PDFDocumentCreate {
	public static void main(String[] args) {
		PDDocument document = new PDDocument();//빈 PDF 문서를 만든다 . 
		try {
			document.save("D:/EDOC_JAVA/Study/pdfprac/test.pdf");
			System.out.println("PDF Create");
			document.close();
			
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

PDF파일생성후 빈페이지를 생성한다.

import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;

public class AddingPage {
	public static void main(String[] args) {
		//create PDF documet object
		PDDocument document = new PDDocument();
		for(int i = 0 ; i<10 ; i++){//총 10 페이지가 만들어짐 
			//create a blanck Page 
			PDPage blanckPage = new PDPage();
			
			//Adding the blank page to the doucument;
			document.addPage(blanckPage);
		}
		
		//Saving the document 
		try {
			document.save("D:/EDOC_JAVA/Study/pdfprac/blanck.pdf");
			System.out.println("PDF created");
		} catch (IOException e) {
			e.printStackTrace();
		}
				
	}
}

기존의 PDF파일에 페이지를 추가

import java.io.File;
import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.encryption.InvalidPasswordException;

	public static void main(String[] args) {
		
		//Loading an exsiting document
		File file = new File("D:"+File.separator+"DEV_DOC"+File.separator+"dev_book"+File.separator+"테스트주도개발ocr.pdf");
		try {
			PDDocument document = PDDocument.load(file);
			System.out.println("PDF loaded");
			
			//adding a blank page to the document
			document.addPage(new PDPage());
			
			//Saving the document
			document.save("D:"+File.separator+"EDOC_JAVA"+File.separator+"Study"+File.separator+"pdfprac"+file.separator+"testadd.pdf");
			
			//close the document
			document.close();
		} catch (InvalidPasswordException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		
		
	}
}

PDF 문서에도 속성이 있다 .
이런 속성의 키와 값으로 이루어져 있다 .

PDF의 문서의 속성의 다음과 같다 .

File - 이 속성은 파일의 이름을 포함한다.

Title - 이 속성을 사용하여 문서의 제목을 설정할수 있다.

Author - 이 속성을 사용하여 문서 작성자의 이름을 설정할 수 있다.

Suject - 이 속성을 사용하여 PDF 문서의 제목을 지정할 수있다.

Keywords - 이 속승ㄹ 사용하면 문서를검색 할 수있는 키워드를 나열 할 수있다.

Created - 이 속성을 사용하면 생성된 날짜를 설정할 수 있다.

Modified - 문서의 수정된 날짜를 설정할 수 있다.

Application - 이 속성을 사용하여 문서의 응용 프로그램을 설정할 수 있다.

문서 속성 설정하기

setAuthor(String author)
- PDF 문서 작성자 속성 값 설정에 사용

setTitle(String title)
- Title속성 설정에 사용

setCreator(String creator)
- Creator라는 PDF 문서의 속성값을 설정하는데 사용된다.
setSubject(String subject)
- Subject를 설정한다.
setCreattionDate(Calendar date)
- 이 메서드는 CreationDate 라는 PDF 문서의 속성 값을 설정하는 데 사용된다.
setModificationDate(Calendar date)
- ModificationDate 라는 PDF 문서의 속성 값을 설정하는 데 사용된다.
setKeywords(String keywords list)
- PDF 문서의 Keywords 속성 값을 설정하는 데 사용된다.
