What I'm doing is cropping a list of PDDocuments down to small rectangles. Then I want to combine all the new cropped PDDocuments into one new PDDocument but I want them in specific locations.
Here’s an example of what I’m trying to do. [cid:[email protected]] I am currently doing something similar but I'm only using the original PDDocument. private void drawSixUp(PDDocument document, PDPage page) throws IOException { final float rectangle_width = 2.25f * PDFx; final float rectangle_x_separation = 9.0f / 16.0f * PDFx; LayerUtility layerUtility = new LayerUtility(document); PDXObjectForm mountable = layerUtility.importPageAsForm(document, 0); mountable.getPDStream().addCompression(); PDPageContentStream contentStream = new PDPageContentStream(document, page, true, true); contentStream.appendRawCommands("q\n".getBytes("ISO-8859-1")); //draw additional rectangles AffineTransform transform = new AffineTransform(); transform.translate(rectangle_width + rectangle_x_separation, 0); contentStream.drawXObject(mountable, transform); transform = new AffineTransform(); transform.translate(rectangle_width * 2 + rectangle_x_separation * 2, 0); contentStream.drawXObject(mountable, transform); contentStream.appendRawCommands("Q\n".getBytes("ISO-8859-1")); contentStream.close(); } I’ve tried doing the same thing but for some reason it’s not working. Here is what I’m trying: public void drawMealDealStore(List<PDDocument> pdfImagesList) throws IOException { PDDocument document = new PDDocument(); PDPage page = new PDPage(); document.addPage(page); PDPageContentStream contentStream; AffineTransform transform; float couponGap = 0; int i = 1; for (PDDocument pdDocument : pdfImagesList) { LayerUtility layerUtility = new LayerUtility(document); PDXObjectForm mountable = layerUtility.importPageAsForm(pdDocument, 0); mountable.getPDStream().addCompression(); contentStream = new PDPageContentStream(document, page, true, true); contentStream.appendRawCommands("q\n".getBytes("ISO-8859-1")); boolean topRow; if (i != 1 && i % SIX == 1) { page = new PDPage(); document.addPage(page); contentStream = newPDPageContentStream(document, page); couponGap = 0; topRow = true; } else if (i == 1) { couponGap = 0; topRow = true; } else if (i % SIX == TWO || i % SIX == THREE) { couponGap += COUPONGAP; topRow = true; } else if (i % SIX == FOUR) { couponGap = 0; topRow = false; } else { couponGap += COUPONGAP; topRow = false; } transform = new AffineTransform(); if (topRow) { transform.translate((X_INDENT*2) + couponGap, BOTTM_OF_TOP_REC); } else { transform.translate((X_INDENT * 2) + couponGap, BOTTM_OF_TOP_REC - (REC_Y_GAP + REC_HEIGHT)); } contentStream.drawXObject(mountable, transform); // restore former graphics state contentStream.appendRawCommands("Q\n".getBytes("ISO-8859-1")); contentStream.close(); pdDocument.close(); i++; } try { document.save("mealDealStore.pdf"); } catch (COSVisitorException e) { e.printStackTrace(); } document.close(); } This should work but all I’m getting is an empty page and the following error: [cid:[email protected]] Any ideas of what I’m doing wrong?
