Returns a BufferedImage as the result of decoding a supplied ImageInputStream with an ImageReader chosen automatically from among those currently registered.

Usage

From source file:filters.BaseFilter.java

public void filter(URL url, OutputStream output, FilterOptions options)
        throws IOException, EmptyExtensionException, NotSupportedFormatException, FileTooBigException {
    String format = SupportedFormats.supportFormat(url.toString());
    if (StringUtils.isBlank(format)) {
        throw new NotSupportedFormatException();
    }/*from   www .jav  a2  s . c  om*/

    // Calculate size
    HttpURLConnection openConnection = (HttpURLConnection) url.openConnection();
    int contentLength = openConnection.getContentLength();
    if (contentLength > FILE_SIZE_LIMIT) {
        throw new FileTooBigException();
    }
    openConnection.disconnect();

    BufferedImage read = ImageIO.read(url);
    doFilter(read, output, options, format);
