Usage examples:
IMAGINGJAVA-1221 Optimize JPEG2000 memory usage if possible
Image image = Image.load("test.dng");
try {
ByteArrayOutputStream ms = new ByteArrayOutputStream();
try {
// rendering the image - the exception comes from here
image.save(ms, new Jpeg2000Options());
// sending the image by HTTP is emulated using the local storage
RandomAccessFile fs = new RandomAccessFile("test.j2k", "w");
try {
fs.write(ms.toByteArray());
} finally {
fs.close();
}
} finally {
ms.close();
}
} finally {
image.close();
