Gradient in FO

[marco scotoni]

Hi,   I read that someone use command of lineargradient or radialgradient in svg inside Fo to FO->PDF, and it goes... it's that true?    I try using   <fo:instream-foreign-object> <svg width="8cm" height="4cm" viewBox="0 0 800 400" xmlns="http://www.w3.org/2000/svg" version="1.1"> <g>  <defs>    <radialGradient id="MyGradient" gradientUnits="userSpaceOnUse" cx="400" cy="200" r="300" fx="400" fy="200">        <stop offset="0%" stop-color="red" />        <stop offset="50%" stop-color="blue" />        <stop offset="100%" stop-color="red" /> </radialGradient> </defs>   <rect fill="none" stroke="blue" x="1" y="1" width="798" height="398"/>   <rect fill="url(#MyGradient)" stroke="black" stroke-width="5" x="100" y="100" width="600" height="200"/>   </g> </svg> </fo:instream-foreign-object>   but it shows me only a blu rectangle.   any suggest?
