I have a PDF File (ex:Hello.pdf) and what i need to do with this PDF is Read the file and get text content and replace the text with HashMap Values (If find the key in Text) ex:- If PDF Content Text is (My Name is [Name]) and hashMap Key "Name":"Vikrant" Then overwrite this as "My Name is Vikrant" and write it to the PDF. I have Tried iTextPDF Jar but still won't got any logical Solution. /* example inspired from "iText in action" (2006), chapter 2 */
PdfReader reader = new PdfReader("D:/HelloWorld.pdf"); // input PDF
PdfStamper stamper = new PdfStamper(reader,
new FileOutputStream("D:/Bubi_modified.pdf")); // output PDF
BaseFont bf = BaseFont.createFont(
BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED); // set font
//loop on pages (1-based)
for (int i=1; i<=reader.getNumberOfPages(); i++){
// get object for writing over the existing content;
// you can also use getUnderContent for writing in the bottom layer
PdfContentByte over = stamper.getOverContent(i);
// write text
over.beginText();
over.setFontAndSize(bf, 10); // set font and size
over.setTextMatrix(107, 740); // set x,y position (0,0 is at the bottom left)
over.showText("I can write at page " + i); // set text
over.endText();
// draw a red circle
over.setRGBColorStroke(0xFF, 0x00, 0x00);
over.setLineWidth(5f);
over.ellipse(250, 450, 350, 550);
over.stroke();
}
stamper.close();
}
I have Tried PDFStamper(iTextPDF.jar) But this class can put the content to the pdf not edit the earlier Text or Image.
