I want to ask to the ix86 users if they have problem with writing images to Streams with the ImageIO-plugins provided at Java Advanced Imaging SDK. I can observe various behaviour with the JAI/JIIO impl on ix86 platforms running wih windows both J2SE 5 and 6. I tested with an Intel Celeron D using a d3d card and an Amd Sempron with integrated graphics chipsets. Celeron D w/ d3d works but Sempron w/ integrated (S3 graphics) chipset doesn't.
More exactly with a code example, the (ImageWriter).write((StreamMetaData), (IIOImage), (WriteParams)) doesn't get in error but the output file is empty with Sempron and integrated graphics chipset. I can't find any explanation of that issue with JAI/JIIO writiing to x-png Streams though it works well when writing to BufferedImages. There's also a mysterious latency with the JFileChooser on some Windows platform, a bug-issue that's already known at Sun... Here's the code sample :
if (!(data instanceof BufferedImage)) {
                                data = convertToBuffered(data, this);
                            if(!(data instanceof RenderedImage))
                                throw new IOException("READ/WRITE ERROR : Sprite image isn't compatible with RenderedImage. " + data.getClass().getName());
                            ImageWriter w = getWriter(0);
                            IIOMetadata meta = w.getDefaultImageMetadata(ImageTypeSpecifier.createFromRenderedImage((RenderedImage) data), w.getDefaultWriteParam());
                            if (data == null) {
                                throw new NullPointerException("Sprite " + base + " had no data to draw ");
                            IIOImage iioimage = new IIOImage((RenderedImage) data, null, meta);
                            if (w.canInsertImage(-1)) {
                                w.writeInsert(-1, iioimage, w.getDefaultWriteParam());
                            } else {
                                w.write(meta, iioimage, w.getDefaultWriteParam());
                            System.out.println("writing is done.");

Can someone give a tip about that issue ? Huh Huh Huh
