Hi John, try srcPage.getMediaBox().createRetranslatedRectangle(), also for the other boxes.
The returned rectangle from srcPage.getMediaBox() will reflect the negativ coordinates.

We recently ran into a problem where the library we were using would keep ALL the pages in memory. For a quick workaround we have it write out single-page PDF files, then use PDFBox to combine them. We recently found a bug in the way that the pages get modified when combined into a single PDF. When we generate the pages, sometimes the MediaBox starts at negative coordinates. When PDFBox adds that page to a document, it offsets it by that negative amount - which moves the page content up and to the right. Out page combining code looks like this. try (PDDocument doc = new PDDocument(MemoryUsageSetting.setupTempFileOnly())) { for (File pagFile : srcPages) { log.debug("make: page {}", pagFile.getAbsolutePath()); PDPage page = new PDPage(); doc.addPage(page); try (PDPageContentStream contents = new PDPageContentStream(doc, page)) { try (PDDocument sourceDoc = Loader.loadPDF(pagFile, MemoryUsageSetting.setupTempFileOnly())) { PDPage srcPage = sourceDoc.getPage(0); page.setUserUnit(srcPage.getUserUnit()); page.setMediaBox(srcPage.getMediaBox()); page.setCropBox(srcPage.getCropBox()); page.setTrimBox(srcPage.getTrimBox()); // Create a Form XObject from the source document using LayerUtility LayerUtility layerUtility = new LayerUtility(doc); PDFormXObject form = layerUtility.importPageAsForm(sourceDoc, 0); // draw the full form contents.drawForm(form); } } } doc.save(outPDF); } The original Page pdf has a TrimBox[0,0,1296,864], MediaBox[-72,-72,1368,936] The page in the PDFBox combined output has the same TrimBox and MediaBox, BUT the /Form1 it uses to place the contents has a BBox[-72,-72,1368,936] and a Matrix[1,0,0,1,72,72]. I'm not sure why it's adding a Matrix to offset the content. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@pdfbox.apache.org For additional commands, e-mail: users-h...@pdfbox.apache.org
