We have some code kicking around that uses this old internal Sun package for manipulating images, essentially encoding JPEGs to a specific size and quality after reading in / decoding from an inputstream. Code examples below. I would appreciate a best practice replacement example using proper java.* or javax.* APIs.
private void encodeJPEG(BufferedImage bi, BufferedOutputStream out, float quality) throws
ImageFormatException, IOException {
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
param.setQuality(quality, false);
param.setDensityUnit(DENSITY_UNIT);
param.setXDensity(DENSITY);
param.setYDensity(DENSITY);
encoder.setJPEGEncodeParam(param);
encoder.encode(bi);
}
private void initJPEG(File jpegFile) throws FileNotFoundException, IOException,
IOException {
FileInputStream inputStream = new FileInputStream(jpegFile);
try {
JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder(inputStream);
buffImage = decoder.decodeAsBufferedImage();
}
.....error handling.....
}
