Hello.

I use the following code to find out the ImageReader to deal with a certain file:

private static ImageReader createImageReader (final ImageInputStream imageInputStream, final String suffix) throws IOException { try { for (Iterator<ImageReader> iterator = ImageIO.getImageReadersBySuffix(suffix); iterator.hasNext();) { ImageReader reader = iterator.next(); String pluginClassName = reader.getOriginatingProvider().getPluginClassName();

logger.finer(">>>> testing reader: " + reader + ", pluginClassName: " + pluginClassName);

if ((reader != null) && !unwantedPlugins.contains (pluginClassName) && reader.getOriginatingProvider().canDecodeInput (imageInputStream)) { reader.setInput(imageInputStream); logger.finer(">>>> returning reader: " + reader + ", pluginClassName: " + pluginClassName); return reader; } }

throw new IOException("No ImageReader for the suffix: " + suffix); }

Of course JAI-IMAGEIO is in the classpath. In facts in the log I see:

13:24:02.810 [AWT-EventQueue-1 ] FINE ReadOp - getImageReader(/Users/fritz/Business/Tidalwave/Projects/blueMarine/ Test/Pleiades Small Set/w1.tif) 13:24:02.810 [AWT-EventQueue-1 ] FINER ReadOp - >>>> suffix is tif 13:24:02.812 [AWT-EventQueue-1 ] FINER ReadOp - >>>> testing reader: com.sun.imageio.plugins.tiff.TIFFImageReader@5b8c7f, pluginClassName: com.sun.imageio.plugins.tiff.TIFFImageReader

Nevertheless, the "canDecodeInput()" returns false and the method fail. This happens only on Mac OS X; the same application works fine with Linux and Windows. What's the problem?

PS Maybe I've read in the past months about a possible problem with TIFFs and Mac OS X but I can't recall.
