Thanks Cameron,
The code that you gave fixed partially the problem : there was still a black
line on top of the generated GIF. I finally corrected the problem by using
the following code, which use another way to produce a BufferedImage :
(Simplified version - procedural - some objects creation omit, used fake
static objects instead )
// First create an outputStream to hold the hold the SVGDocument
ByteArrayOutputStream ostream = new ByteArrayOutputStream ();
// Write the SVGDocument in the ByteArrayOutputStream using DOMUtilities to
Serializes it.
PrintWriter writer = new PrintWriter(ostream );
DOMUtilities.writeDocument(svgDocument, writer);
writer.flush();
writer.close();
ByteArrayInputStream inputStream = new ByteArrayInputStream(new String
(ostream .toByteArray()).getBytes("utf-8"));
TranscoderInput input = new TranscoderInput(inputStream );
ImageTranscoder.transcode(input, null);
After, the "transcode" code in ImageTranscoder does what you suggested :
> if(hints.containsKey(KEY_BACKGROUND_COLOR))
> {

> g2d.setPaint(bgcolor);
> g2d.fillRect(0, 0, w, h);

The g2d.setComposite(AlphaComposite.SrcOver); line seems to correct the
other problem of the black line...
Thanks!!!!
