Thank you [~tilman]
I got it.

Thank you [~tilman]
So what the solution for that ?
there is the code :
{code:java}
public JSONObject overLay(String firstOverlayFile, String secondOverlayFile,
String outputFileName) throws IOException {
JSONObject json = new JSONObject();
Overlay overlayer = new Overlay();
shell.log(5, "=== overLay.firstPageOverlayFile === ",firstOverlayFile);
shell.log(5, "=== overLay.lastPageOverlayFile === ",secondOverlayFile);
overlayer.setOverlayPosition(Overlay.Position.FOREGROUND);
PDDocument firstFile = PDDocument.load(aws.getAwsFile(firstOverlayFile));
PDDocument secondFile = PDDocument.load(aws.getAwsFile(secondOverlayFile));
String pdfFirstData = pdfContent(firstFile);
String pdfLastData = pdfContent(secondFile);
overlayer.setInputPDF(firstFile);
overlayer.setAllPagesOverlayPDF(secondFile);
Map<Integer, String> ovmap = new HashMap<Integer, String>();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
overlayer.overlay(ovmap).save(baos);
InputStream overlayedContent = new ByteArrayInputStream(baos.toByteArray());
IOUtils.copy(overlayedContent, new FileOutputStream(outputFileName));
firstFile.close();
secondFile.close();
overlayer.close();
shell.log(5, "=== overLay === ",outputFileName);
json.put("fileName",outputFileName);
json.put("pdfFirstData", pdfFirstData);
json.put("pdfLastData", pdfLastData);
return json;
}
{code}
> Overlayed PDF file do not shows the difference

> There are two differences in this two files, in the table on last page and in
> the table on the previous page the second row, column "% since inception" has
> values 11.74 in one pdf and 11.75 in another one. The textual html diff picks
> up and shows both cases. However, visual overlay shows this on page 5, but
> doesn't show on page 6.
