gif image Auto-Scale

[Michael Voyes <qm...@ocegr.fr>]

Ok, it is working with the command add-on concerning memory. 
Furthermore, the result is GOOD.
I'm therefore wondering if my code is good :

remember :

OutputStream outputStream = new FileOutputStream (outputFileName);
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
TranscoderOutput output = new TranscoderOutput(ostream);
SVGAbstractTranscoder transDoc = new SVGAbstractTranscoder();
transDoc.transcode((Document)doc, (OutputStream)outputFileName, output);
Filter f = transDoc.root.getGraphicsNodeRable(true);
curTxf = new AffineTransform();
RenderContext rc = new RenderContext(curTxf, null, null);
RenderedImage img = f.createRendering(rc);

you seem to not agree with this piece of code to Render the doc DOM. 
Again, if this code is causing the wrong result i described (and it 
seems to be the case), i'm asking what is your piece of code advise to 
get the good result taking a DOM in input ?

    I would take the approach taken in 
contrib/tiledTranscoder/TiledImageTranscoder (which it looks like
you filched code from).  In particular I'm not sure the GVT tree
is good after 'transcode(...)' completes (the bridge context is
disposed of which _may_ be the source of your problems).

    So I would subclass SVGAbstractTranscoder and generate your
output in the transcode method.  Don't try and use anything from
the transcoder after the transcode method completes.
