JPEG (Java)
January 17th, 2003
Version 0.1 – A Java library to read and write JPEG files. So far only provides support for reading and writting metadata (EXIF and IPTC). Image encoding and decoding is not working yet.
Latest Version
Version 0.1 – January 15th, 2003
Description
com.zonageek.jpeg is a java library to read and manipulate jpeg files.
So far it can parse the file structure, providing access to the raw data of each block. It can also understand EXIF and IPTC blocks, allowing both read and write of metadata.
Coming soon is the ability to decode and encode image data, thus allowing for full image reading and generation.
And once that is done, the next step will be loseless rotation and cropping.
But those new features will take time, so don’t hold your breath.

Usage
Not much information right now. Check the com.zonageek.jpeg.JpegTest class for some sample usage code.
January 31st, 2008 11:15 AM I am having a little trouble though adding metadata to jpeg files that did not previously have metadata. When looking at the fields from the class ExifTagList, fields from the "ifd0" part of the ExifBlock section seem to add just fine, but I cannot seem to get fields from the "exif" part added. I am able to modify fields from this section in an image where they already exist, but I would like to be able to add them to a new image.

January 31st, 2008 11:15 AM Hi, First, thanks for the java Jpeg toolkit. I've found it a great help for modifying metadata in my jpegs. I am having a little trouble though adding metadata to jpeg files that did not previously have metadata. When looking at the fields from the class ExifTagList, fields from the "ifd0" part of the ExifBlock section seem to add just fine, but I cannot seem to get fields from the "exif" part added. I am able to modify fields from this section in an image where they already exist, but I would like to be able to add them to a new image. Any thoughts? Thanks
