Does anyone have working JAVA code using PDFBOX for this?

OK, as usual the program does just what you tell it.

Save target instead of document (bottom).

Only saves one page though, but I hope that is a small thing.


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]); <==== change from document to target
}
}
