Hi Jessy, here a few points about this issue: * PDF support is relatively new and there are a few/lot (?) of cases which work differently opposed to PPTX->PNG * I can have a look at your input file and try to figure out what's wrong - either send it to the list or to me privately * Cascaded properties from themes are a source of errors - POIs handling is a bit shirtsleeved in this area * Please try out the convenience tool PPTX2PNG (http://poi.apache.org/components/slideshow/ppt-wmf-emf-renderer.html) * Also check the nightly - description about how to use the nightly is also in the above link. In case I fix something, it would be cool, if you could verify it

HI all, I am trying to convert pptx file containing a custom theme and two text boxes to pdf. I am able to convert into PDF, but the theme size is reduced and the two text box is printed on a white background.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)); 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(); }
