[jira] [Commented] (PDFBOX-3744) Can't see images on PDF when using ByteArrayOutputStream

    [ https://issues.apache.org/jira/browse/PDFBOX-3744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15956762#comment-15956762 ] 

Julien Keruzec commented on PDFBOX-3744:
----------------------------------------

I resolve the problem. Problem was that PDF was return in a POST HTTP request (Spring framework Rest controller), I think post was modifying the PDF somehow ...
I change it for GET request and PDF is well displayed.
Sorry for disturbance.. 
Regards,

> Hello,
> I have a problem generating a PDF file with an image of a QRCode in JPEG format.
> When I generate the PDF on file system everyting is fine. PDF is displaying all pages with all QR Code images in it.
> As soon as I want to use Outputstream / InputStream my generated PDF result in a blank page and I can't see my image anymore.
> You will find an example of a PDF with no image displayed in attachement
> Same thing occured with V1.8.9 of PDFBOX.
> Here's the code I use :
> My images come from a list of InputStream 
> {code:java}
> List<InputStream> images
> {code}
> {code:java}
> InputStream is = null;
> 		ByteArrayOutputStream os = new ByteArrayOutputStream();
> 		try {
> 			PDDocument document = new PDDocument();
> 			for (InputStream image : images) {
> 				this.addImageToPDF(document, image, width, height);
> 			}
> //			File f = new File(System.getProperty("java.io.tmpdir") + File.pathSeparator + "test.pdf");
> //			document.save(f);
> 			document.save(os);
> 			document.close();
> 			
> 			is = new ByteArrayInputStream(os.toByteArray());
> {code}
> Generation of page :
> {code:java}
> protected void addImageToPDF(PDDocument document, InputStream image, int width, int height) throws IOException {
> 		PDRectangle pageFormat = null;
> 		PDPage page = new PDPage();
> 		PDImageXObject  ximage = null;
> 		ximage = JPEGFactory.createFromStream(document, image);
> 		if(ximage.getWidth() > ximage.getHeight()){
> 			pageFormat = new PDRectangle(height,width);
> 			pageWidthWithMargin = height - 20;
> 			pageHeightWithMargin = width - 20;
> 		}
> 		else{
> 			pageFormat = new PDRectangle(width,height);
> 			pageWidthWithMargin = width - 20;
> 			pageHeightWithMargin = height - 20;
> 		}
> 		page.setMediaBox(pageFormat);
> 		document.addPage(page);
> 		PDPageContentStream contentStream = new PDPageContentStream(document, page);
> 		float scale = getScale(ximage);
> 		contentStream.drawImage(ximage, 10, (pageHeightWithMargin+10) - ximage.getHeight()*scale, 
> 				ximage.getWidth()*scale, ximage.getHeight()*scale);
> 		contentStream.close();
> 	}
> {code}
> Can anyone help me on this ?
