Julien Keruzec updated PDFBOX-3744:
-----------------------------------
Description:
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
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) 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(PAGE_HEIGHT,PAGE_WIDTH);
pageWidthWithMargin = PAGE_HEIGHT - 20;
pageHeightWithMargin = PAGE_WIDTH - 20;
}
else{
pageFormat = new PDRectangle(PAGE_WIDTH,PAGE_HEIGHT);
pageWidthWithMargin = PAGE_WIDTH - 20;
pageHeightWithMargin = PAGE_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 ?
