Bottom image border.

I need image with border after int.
I used next code:
										<fo:block>
	<fo:external-graphic src="url('{@static}{@banner}')"
	 content-height="scale-to-fit"
	 content-width="100%"
	 width="100%"
	 border-bottom="1pt solid black"
	 border-top="1pt solid black"
	/>
</fo:block>
Image size less than maximum block size.
I get line but with boss after image end.
