Examples with J2KImageReader com.sun.media.imageioimpl.plugins.jpeg2000.J2KImageReader used on opensource projects

Example 1 with J2KImageReader

use of com.sun.media.imageioimpl.plugins.jpeg2000.J2KImageReader in project bioformats by openmicroscopy.

the class JAIIIOServiceImpl method readRaster.

/* @see JAIIIOService#readRaster(InputStream, JPEG2000CodecOptions) */
@Override
public Raster readRaster(InputStream in, JPEG2000CodecOptions options) throws IOException, ServiceException {
    J2KImageReader reader = getReader();
    MemoryCacheImageInputStream mciis = new MemoryCacheImageInputStream(in);
    reader.setInput(mciis, false, true);
    J2KImageReadParam param = (J2KImageReadParam) reader.getDefaultReadParam();
    if (options.resolution != null) {
        param.setResolution(options.resolution.intValue());
    }
    Raster raster = reader.readRaster(0, param);
    mciis.close();
    reader.dispose();
    return raster;
}
