----------------------------------
Description:
DCTFilter calls findRasterReader and returns the first reader, on error it
should try the 2nd reader as JDK cant read all jpegs
{code:java}
protected void findImageReader(String formatName, String errorCause,
InputStream encoded, ImageReaderRunner runner) throws IOException
{
Iterator<ImageReader> readers =
ImageIO.getImageReadersByFormatName(formatName);
ImageInputStream iis = ImageIO.createImageInputStream(encoded);
iis.mark();
Exception exception = null;
String error = "Cannot read " + formatName + " image: " + errorCause;
try {
while (readers.hasNext()) {
ImageReader reader = readers.next();
if (reader.canReadRaster()) {
try {
reader.setInput(iis);
runner.run(reader);
return;
} catch (Exception e) {
exception = e;
error = e.getMessage();
iis.reset();
} finally {
reader.dispose();
}
}
}
} finally {
iis.close();
}
throw new RuntimeException(error, exception);
}
interface ImageReaderRunner {
void run(ImageReader reader) throws IOException;
}
{code}
