preserveAspectRatio, 'stretching' an image not working by percentage, and batik

[Arian Hojat <ar...@gmail.com>]

Hello all, 
I view an svg in adobe svg viewer and it stretches the width and
height to be 100% of the svg document. but batik does not correctly
render it when i transcode (it will stretch the height so it fills up
the svg document. But it wont 'stretch' the width to match the svg doc
as well.)... Could it be adobe svg viewer is just leniant? or Batik is
not leniant with my code.

Anyone got ideas. I dont really override aspect ratio settings since
svg viewer interprets it fine.

Here are my svg code batik makes and images if anyone is more interested.

<svg contentScriptType="text/ecmascript" width="720"
xmlns:xlink="http://www.w3.org/1999/xlink" zoomAndPan="magnify"
contentStyleType="text/css" height="360"
preserveAspectRatio="xMidYMid meet" xmlns="http://www.w3.org/2000/svg"
version="1.0">

<image x="0" y="0" width="720"
xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="8.jpg"
xlink:type="simple" xlink:actuate="onLoad" height="360"
preserveAspectRatio="xMidYMid meet" xlink:show="embed"/>

<image x="0" y="0" width="100%"
xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="4.png"
xlink:type="simple" xlink:actuate="onLoad" opacity="0.7" height="100%"
preserveAspectRatio="xMidYMid meet" xlink:show="embed"/>

</svg>

    The mentioned behavior is a flat out bug in ASV.  They ignore
the value of preserveAspectRatio and always behave as if it were
'none'.  The behavior you describe is the correct behavior for
the value you have provided 'xMidyMid meet'.

   No the 'svg viewer' interprets it wrong.  Give it the proper value
'none' and your document will render as you want in Batik, and any
other con formant SVG viewer/renderer you pass it to.
