解决方案
以下是使用 Java 将文本添加到 PDF 文档的示例程序。
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.PDPageContentStream;
import org.apache.pdfbox.pdmodel.font.PDType1Font;
public class AddingTextToAPdf {
public static void main(String args[]) throws IOException {
//Loading an existing document
PDDocument doc = PDDocument.load(new File("C:/pdfBox/AddText_IP.pdf"));
//Creating a PDF Document
PDPage page = doc.getPage(0);
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
//Begin the Content stream
contentStream.beginText();
//Setting the font to the Content stream
contentStream.setFont( PDType1Font.TIMES_ROMAN, 16 );
//Setting the position for the line
contentStream.newLineAtOffset(25, 725 );
String text = "This is an example of adding text to a page in the pdf document.
we can add as many lines as we want like this using the draw string method
of the ContentStream class";
//Adding text in the form of string
contentStream.showText(text);
//Ending the content stream
contentStream.endText();
System.out.println("Content added");
//Closing the content stream
contentStream.close();
//Saving the document
doc.save(new File("C:/pdfBox/AddText_OP.pdf"));
//Closing the document
doc.close();
}
}
