Hello, world!
My project involves resizing images. I need to keep the EXIF metadata
though. I wrote a bit of code* that copies EXIF data from the original
image to the resized one, but it instead copies the entire image, not
just the metadata.
So I need either
1. A way to copy _only_ the metadata between images, or
2. A way to read the whole image with Sanselan, manipulate the image
data, and then write the whole thing, metadata and all, to a new file.
I haven't been able to find a solution reading any documentation I could
find, tutorials, or the sample code. Thanks!
* Code here:
try {
IImageMetadata metadata = Sanselan.getMetadata(original);
JpegImageMetadata jpegMetadata = (JpegImageMetadata) metadata;
if (jpegMetadata != null) {
TiffImageMetadata exif = jpegMetadata.getExif();
if (exif != null) {
TiffOutputSet outputSet = exif.getOutputSet();
OutputStream outputStream = new BufferedOutputStream(new
FileOutputStream(copy));
new ExifRewriter().updateExifMetadataLossless(original,
outputStream,
outputSet);
outputStream.close();
// ...
