R4R Java SourceCode Set Different Alignment Of PDF Using Java


Set Different Alignment Of PDF Using Java

Here we are creating a PDF document with different pages that have different alignments. To set alignment we are using setAlignment(int arg).

To create a PDF using java you need iText API.You can download from website.This is an open source jar .Then you have to set class path of this iText jar.

There are basic five steps to create PDF:

Step1: Creation of a document-object

Document document = new Document();

Step2: Create a writer that listens to the document and directs a PDF-stream to a file.

PdfWriter.getInstance(document, new FileOutputStream(
"Alignment.pdf"));

Step3: Open the document

document.open();

Step4: Create an object of paragraph set alignment ,add contant into paragraph and finaly add the paragraph with document

Paragraph paragraph = new Paragraph();
paragraph.setAlignment(Element.ALIGN_RIGHT);

paragraph.add("RIGHT Alignment");
document.add(paragraph);

Step 5: Close the document

document.close();:
