I know I asked this before. But was just sent to general PDFBOX help pages. Most if not all examples there are "HELLO WORLD" types.
But does ANYONE have an actual working example of placing a PDF inside of another PDF using PDFBOX? Can you share the code if so?
I have a small (A) PDF. I want to place it on the top of another (B) PDF. So when the class runs, I will end up with ONE page. PDF (B) would remain intact as it was before I executed the class, with PDF (A) on top of it. Both PDF (A) small and the other PDF (B) would pre-exist.
Have tried to make multiple examples work that I got from stack overflow.
The one that was published on stack overflow to my question above created both the PDFs in the code. They were not external. When feeding in external PDFs, I got a blank one. But not really sure if my doctoring to that one was why it created a blank page.
My question to stack overflow:
https://stackoverflow.com/questions/47295391/create-a-one-page-pdf-from-two-pdfs-using-pdfbox/47349671?noredirect=1#comment81672358_47349671
My doctored code:
PDDocument document = new PDDocument();
File topfile = new File(args[0]);
PDDocument topSource = PDDocument.load(topfile);
File bottomfile = new File(args[1]);
PDDocument bottomSource = PDDocument.load(bottomfile);
PDDocument target = new PDDocument();
LayerUtility layerUtility = new LayerUtility(target);
PDFormXObject topForm = layerUtility.importPageAsForm(topSource, 0);
PDFormXObject bottomForm = layerUtility.importPageAsForm(bottomSource, 0);
float height = topForm.getBBox().getHeight() + bottomForm.getBBox().getHeight();
float width, topMargin, bottomMargin;
if (topForm.getBBox().getWidth() > bottomForm.getBBox().getWidth()) {
width = topForm.getBBox().getWidth();
topMargin = 0;
bottomMargin = (topForm.getBBox().getWidth() - bottomForm.getBBox().getWidth()) / 2;
} else {
width = bottomForm.getBBox().getWidth();
topMargin = (bottomForm.getBBox().getWidth() - topForm.getBBox().getWidth()) / 2;
bottomMargin = 0;
}
PDPage targetPage = new PDPage(new PDRectangle(width, height));
target.addPage(targetPage);
PDPageContentStream contentStream = new PDPageContentStream(target, targetPage);
if (bottomMargin != 0)
contentStream.transform(Matrix.getTranslateInstance(bottomMargin, 0));
contentStream.drawForm(bottomForm);
contentStream.transform(Matrix.getTranslateInstance(topMargin - bottomMargin, bottomForm.getBBox().getHeight()));
contentStream.drawForm(topForm);
contentStream.close();
document.save(args[2]);
}
}
Other examples have constructors or methods not found (like the code below) and the class cannot be saved and created.
New to Java. Not like I have not been digging and trying for weeks. But just keep hitting the wall with this one. Not like I really understand this code that well either. Copy/Paste /try technology.
Part of the problem too with PDFBOX being free is there is really not a ton of help out there.
My errors with the code below:
List
it is a raw type and should be parameterized.
(getAllPages),
Method is undefined.
PDFObjectForm
Cannot be resolved to a type
AffineTransform,
Cannot resolve to a type.
