Description

After overlaying two documents, everything in the source is black & white only. I uploaded a screenshot to

May relate to PDFBOX-2401.

Some more details: I'm doing everything in-memory, not operating on files. This is the sample code:

    public static byte[] mergeOntoLetterhead(byte[] originalPdf) throws IOException, COSVisitorException {
        PDDocument pdf = PDDocument.load(new ByteArrayInputStream(originalPdf));
        if (pdf.getNumberOfPages() == 0) {
            return originalPdf;
        }
        PDDocument template = readTemplate();
        if (null != template) {
            Overlay overlay = new Overlay();
            pdf = overlay.overlay(template, pdf);
        } else {
            logger.error("Could not load letterhead PDF");
            return originalPdf;
        }
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        pdf.save(outputStream);
        return outputStream.toByteArray();
    }
