I am trying to convert a pptx to pdf using the below command. i have custom
background design or image in my pptx along with two text fields. The problem
is i am not able to convert the ppt to pdf correctly, the image and text box
are scattered around in different sizes. Any insights will be helpful.Code below
static void convertToPdf(String fileName) throws IOException, DocumentException
{
FileInputStream inputStream = new FileInputStream(pptLocation +
fileName + PPT);
double zoom = 2;
AffineTransform at = new AffineTransform();
at.setToScale(zoom, zoom);
Document pdfDocument = new Document();
PdfWriter pdfWriter = PdfWriter.getInstance(pdfDocument, new
FileOutputStream(pdfLocation + fileName + PDF));
PdfPTable table = new PdfPTable(1);
pdfWriter.open();
pdfDocument.open();
Dimension pgsize = null;
Image slideImage = null;
BufferedImage img = null;
XMLSlideShow ppt = new XMLSlideShow(inputStream);
pgsize = ppt.getPageSize();
List<XSLFSlide> slides = ppt.getSlides();
pdfDocument.setPageSize(new Rectangle((float) pgsize.getWidth(),
(float) pgsize.getHeight()));
pdfWriter.open();
pdfDocument.open();
for (int i = 0; i < slides.size(); i++) {
img = new BufferedImage((int) Math.ceil(pgsize.width * zoom), (int)
Math.ceil(pgsize.height * zoom), BufferedImage.TYPE_INT_RGB);
Graphics2D graphics = img.createGraphics();
graphics.setTransform(at);
graphics.setPaint(Color.white);
graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width,
pgsize.height));
/*for(XSLFShape shape : slides.get(i))
{
shape.draw(graphics, new Rectangle2D.Float(0, 0, pgsize.width,
pgsize.height));
}*/
slides.get(i).draw(graphics);
graphics.getPaint();
slideImage = Image.getInstance(img, null);
table.addCell(new PdfPCell(slideImage, false));
}
pdfDocument.add(table);
pdfDocument.close();
pdfWriter.close();
}
