Example 1 with ResettableInputStream

use of net.pms.util.ResettableInputStream in project UniversalMediaServer by UniversalMediaServer.

the class ImagesUtil method parseImage.

/**
 * Parses an image file and stores the results in the given
 * {@link DLNAMediaInfo}. Parsing is performed using both
 * <a href=https://github.com/drewnoakes/metadata-extractor>Metadata Extractor</a>
 * and {@link ImageIO}. While Metadata Extractor offers more detailed
 * information, {@link ImageIO} offers information that is convenient for
 * image transformation with {@link ImageIO}. Parsing will be performed if
 * just one of the two methods produces results, but some details will be
 * missing if either one failed.
 * <p><b>
 * This method consumes and closes {@code inputStream}.
 * </b>
 * @param file the {@link File} to parse.
 * @param media the {@link DLNAMediaInfo} instance to store the parsing
 *              results to.
 * @throws IOException if an IO error occurs or no information can be parsed.
