PDF Page with image rotating with itext API addTemplate

I have pages in PDF document which when you look at in Acrobat reader are images (but when you look at them in the Adobe editor they are text with a background image).

These input PDF pages are getting processed using addTemplate method of PdfContentByte class of itext API.

The call cb.addTemplate(page, 1, 0, 0, 1, 0, 0) is not suppose to rotate the read page, but it does.

When you look at the resultant page, the pages with background image get rotated.
And it is only happening to the image pages, not to others. Do you know why?

Another thing observed is that irrespective of the orientation of the image in the "input.pdf", the resultant "output.pdf" document always is in one particular orientation. That means it is read that way by this line --->

PdfImportedPage page = writer.getImportedPage(reader, currentPageNumber++);

Here is the complete code which I have put so that it is easy to run(I have removed many details, to focus on the issue)
