FOP does not do any resampling of images for PDF or PostScript output.
Images are always embedded as is, i.e. in their original size.
You could work around that by embedding the image inside a small SVG
wrapper. But you need to apply a dummy filter to force Batik to do the
resampling. Something like:
<svg:filter id="MyFilter" filterUnits="objectBoundingBox" x="0%" y="0%"
width="100%" height="100%">
<svg:feColorMatrix type="hueRotate" in="SourceGraphic" values="0"/>
</svg:filter>
No guarantees on the quality of such an approach.
