是否可以在PDFBOX中对齐文本？

public class PDFBoxTextAlignment {
    public static void main(String[] args) {
        try (PDDocument document = new PDDocument()) {
            PDPage page = new PDPage();
            document.addPage(page);

            try (PDPageContentStream contentStream = new PDPageContentStream(document, page)) {
                contentStream.beginText();
                contentStream.setFont(PDType1Font.HELVETICA, 12);
                contentStream.newLineAtOffset(100, 700);

                // 左对齐
                contentStream.showText("Left Aligned Text");
                contentStream.newLineAtOffset(0, -20);

                // 右对齐
                contentStream.endText();
                contentStream.beginText();

                contentStream.endText();

                // 居中对齐
                contentStream.beginText();
                contentStream.setFont(PDType1Font.HELVETICA, 12);
                contentStream.newLineAtOffset(200, 650);

                contentStream.endText();

                // 两端对齐
                contentStream.beginText();
                contentStream.setFont(PDType1Font.HELVETICA, 12);
                contentStream.newLineAtOffset(100, 600);
                contentStream.showText("Justified Text");
                contentStream.endText();
            }

            document.save(new File("aligned_text.pdf"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
