xml - Image not displaying completely -

-

i need display svg image pdf file. below xslt code:

<fo:block text-align="left"           display-align="left"           absolute-position="absolute"           left="-1.5cm"           top="-1cm">   <fo:external-graphic content-width="scale-to-fit"                          width="100%"                          content-height="50%"                          scaling="uniform">     <xsl:attribute name="src">          <xsl:value-of select="$src" />     </xsl:attribute>   </fo:external-graphic> </fo:block>

explaination: xml has many images. above code runs in loop , displays images 1 one. images height more page height, image getting cut. tried giving height = 50%. image width reducing.

basically want image should fit in block. , bigger images should not cut. should fit in block given. please help.

but if reduce height, width gets reduced.

this presumably because have specified scaling="uniform" on graphic. "preserve aspect ratio" (see relevant part of specification here).

<fo:external-graphic content-width="scale-to-fit"                      width="100%"                      content-height="50%"                      scaling="non-uniform">    <!--...--> </fo:external-graphic>
