Brian:
1) Drop down the text in a block on the page. I would put it in an absolute
container in a small font to ensure it all fits and will not cause a flow
problem.
2) Stamp the image over the top using an absolute positioned container whose
z-order is higher than the block, usually placed at the end of the flow for
that page.
3) You can control paging by inserting a simple structure like:
<fo:block break-after="page"><fo:leader/></fo:block>
So you would have something like this .... have not tested but should work
...
<fo:block-container> <!-- make absolute and place on the page -->
<fo:block>Searchable text here</fo:block>
</fo:block-container>
<fo:block-container> <!-- make absolute and place on the page over the text
block above -->
<fo:block>
<fo:external-image src="url('mytif.tif')"/>
</fo:block>
<fo:block-container>
<fo:block break-after="page"><fo:leader/></fo:block> <!-- go to next page
-->
If you wish to do it in a flow ... this is also possible. Just design the
block containers to overlap each other. Just do the opposite of this
example:

Subject: [xep-support] Searchable image PDFs
I'm giving this a bump, since I haven't found a solution. I'm attempting to
build a PDF where the TIFF page-images are visible and the embedded OCR is
not. (Though the OCR is searchable.)
I've tried including the page-image file as an external graphic, with the
OCR in a hidden block (<fo:block visibility="hidden"> ... </fo:block>), but
the OCR remains visible.
I feel like I'm missing something obvious.
