----------------------------------
Summary: Unable to process overlay on Cognos PDF documents
Key: PDFBOX-4044
URL: https://issues.apache.org/jira/browse/PDFBOX-4044
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 2.0.8
Reporter: Ad Kooiman
Attachments: confidential_overlay.pdf, report_cognos_merged.pdf,
report_cognos_overlayed.pdf
Since we upgrade from PDFBox 1.x to PDFBox 2.0.8, we cannot overlay PDF
documents anymore. These PDF documens are from Cognos Reporting and still works
fine with PDFBox 1.x.
Attached files:
report_cognos_merged.pdf, a document that contains an intro page that was
succesfully merged into a cognos report. Page 2 and 3 are the original cognos
report pages.
confidential_overlay.pdf, an overlay pdf document
report_cognos_merged.pdf, the resulting document after processing the overlay
To reproduce, use the attached report_cognos_merged.pdf and overlay this with
the attached confidential_overlay.pdf. The resulting attached file
report_cognos_overlayed.pdf only shows an overlay on the first page. The other
pages are not overlayed.
Code snippet used to overlay:
{code}
public void addLayer() throws Exception {
PDDocument inDocument = PDDocument.load(basePdf);
PDDocument layoutDocument = PDDocument.load(overlayLayout);
LayerUtility layerUtility = new LayerUtility(inDocument);
PDFormXObject layerObject =
layerUtility.importPageAsForm(layoutDocument, 0);
AffineTransform transform = new AffineTransform();
for (int i = 0; i < inDocument.getNumberOfPages(); i++) {
layerUtility.appendFormAsLayer(inDocument.getPage(i), layerObject,
transform, layer + "_" + i);
}
layerUtility.getDocument().save(outPdf);
}
{code}
