-----------------------------------------------------------------------------

The Apache Commons Imaging team is pleased to announce the commons-imaging-1.0-alpha3 release!

Apache Commons Imaging (previously Sanselan) is a pure-Java image library.

New features
------------

* Add CIELAB and DIN99 conversion, reduce code duplication, and issues related to zero-division and precision.  Issue: IMAGING-283. Thanks to Wanja Gayk. 
* Imaging.getBufferedImage() drops alpha layer for TIFF images.  Issue: IMAGING-216. Thanks to Gary Lucas. 
* Consolidate redundant methods in TIFF datareaders.  Issue: IMAGING-269. Thanks to Gary Lucas. 
* Add list of TIFF files and example survey application.  Issue: IMAGING-268. Thanks to Gary Lucas. 

Fixed Bugs
----------

* Add PNG predictor to reduce output size.  Issue: IMAGING-330. Thanks to Gary Lucas. 
* Change getExif name to getOutputSet.  Issue: IMAGING-327. Thanks to Gary Lucas. 
* Prevent OutOfMemoryError in BmpImageParser. This can happen when the color palette length is
        a large negative number.  Issue: IMAGING-325. Thanks to Jin Wang. 
* Read TIFFs with 32-bit samples.  Issue: IMAGING-320. Thanks to Gary Lucas. 
* The Imaging ImageParser's used HashMap's before, but on this issue we replaced the maps by proper
        ImagingParameter classes, that encapsulate the parameters for each image format.

        The Imaging class also had the HashMap methods removed, but we also removed the public methods that
        supported parameters. This was due to the complexity to handle cases where users could provide a byte
        array, or file, and parameters. In Java, with or without generics, it was rather difficult to handle
        the cases where users could provide a PNG image stream with TIFF parameters.

        To prevent issues like this, we will improve the ImageParser's API's, and work on either providing
        other ways to customize and create parsers (factories, builders, etc.) or similar ways to use
        the Imaging entry class (like merging parameters or using parameter builders.)

        This was the last blocker issue of the 1.0 release vote, rolled a few years ago.  Issue: IMAGING-159. Thanks to Bruno P. Kinoshita, Gary Lucas, Matt Juntunen. 
* Encoding Support for IPTC metadata.  Issue: IMAGING-168. Thanks to Yavuz Kavus. 
* Array sizes not checked for overflow in BmpImageParser.  Issue: IMAGING-279. 
* ArrayIndexOutOfBoundsException on reading simple GeoTIFF.  Issue: IMAGING-265. Thanks to Gary Lucas. 
* BMP Parser physicalWidthDpi and physicalHeightDpi truncated before rounding off.  Issue: IMAGING-264. 
* Failure when reading a partial raster from a floating-point TIFF  Issue: IMAGING-263. Thanks to Gary Lucas. 
* Fix typos  Issue: IMAGING-291. Thanks to Arturo Bernal. 
* Fix javadoc  Issue: IMAGING-289. Thanks to Arturo Bernal. 
* Fix IptcParserTest on Windows  Issue: IMAGING-308. Thanks to Gary Lucas. 
* Read integer data from GeoTIFFS  Issue: IMAGING-266. Thanks to Gary Lucas. 
* Corrected handling of ExtraSamples tag  Issue: IMAGING-312. Thanks to Gary Lucas. 
* Decoding of Rational Numbers broken when large values present  Issue: IMAGING-285. Thanks to Gary Lucas. 
* Update examples, add GeoTIFF metadata to output  Issue: IMAGING-314. Thanks to Gary Lucas. 
* Read TIFFs with multiple floating-point sampless  Issue: IMAGING-311. Thanks to Gary Lucas. 
* A PNG image using indexed color type but no PLTE chunks throws NPE.  Issue: IMAGING-317. Thanks to OSS-Fuzz. 
* Validate when accessing GIF color table array.  Issue: IMAGING-318. Thanks to OSS-Fuzz.

Minimum Java version: 1.5
Compatibility with 0.97:
  Binary compatible: No.
  Source compatible: No.
  Semantic compatible: No.


Release 0.97
------------
    
 * Rewrote the info.txt files for many images in the sample image library to clarify contribution to project.
 * Removed the images from the www.wpclipart.com Public Domain library.
 * Improved the examples illustrating how to change EXIF metadata.
 * Applied a patch from Niall Pemberton around jdk1.5 compatibility:
    """
    Sanselan claims JDK 1.4 compatibility, but a JDK 1.5 method (Class's getSimpleName() [1]) has been used in JpegRewriter
    """
 * Applied a "Build Improvements" patch from Niall Pemberton:
    """
    I took a look at the propsed 0.96 relelase and have some suggestions to improve the build:
     * Add standard manifest entries to jar
     * Lock down version numbers for maven compiler, surefire and javadoc plugins
     * generate sources jar for the release
     * include the RELEASE-NOTES in the binary distribution
     * include NOTICE/LICENSE files in the javadoc jar
    """

Release 0.96
------------

 * Updated KEYS file.
 * Added more unit tests around BMP.
 * Added more images to the test image suite.
 * Fixed a bug where errors were being wrongly logged to System.out.
 * Moved the example code into the test source directory, to comply with Maven's standard project layout.
 * Added a couple of images to the sample image library that demonstrate a couple variations on Photoshop/IPTC data.  
 * Fixed a small bug in the IPTC constants introduced while cleaning up the constants.
 * Started shift towards moving field-level parsing into BinaryInputStream and BinaryOutputStream.
 * Fixed a png unit test that used a piece of Java 1.6 syntax.
 * Added unit tests around the new IPTC functionality.
 * Added IPTC remove/update/insert functionality.
 * Rewrote the IPTC parsing support.  
 * Added improved support for reading and writing iTXt, tEXt, zTXt Png chunks.
    Added a unit test that demonstrates the feature.
 * Found a new regression wherein DeflaterOutputStream needs to be closed.
 * Added the .tar.bz2 distributions back into the maven assembly descriptors.
 * Moved the example/sample code to a new top-level source folder, "example."
 * Replaced dependency on java.util.zip.DeflaterOutputStream, which is only available in Java 1.6.
 * Added a unit test around reading and writing images in every format.
 * We now sort some (but not all) GIF color tables.
 * Applied the BMP "buffer flushing" bug to the PBM reading and writing code.
 * Fixed a regression around flushing the bit buffer when writing BMPs with very small palettes.
 * Removed assumption about DataBuffer type when reading BMPs.
 * When writing a GIF, we now always include a Graphic Control Extension block, even if its not necessary.
 * We are more defensive about missing GCEs.
 * Lastly, we now set a minimum bound on initial code sizes for LZW-compressed Gif image data.
 * Found a regression in writing TIFFs around strip offsets being properly updated.  Not a LZW issue after all.
    Added a few unit tests around this issue.   
    see: https://issues.apache.org/jira/browse/SANSELAN-6
 * Added ability to remove and update XMP XML in existing JPEG files.
 * Added ability to embed XMP XML when writing the following formats: GIF, PNG, TIFF.
 * Improved handling of tEXt and zTXt PNG text blocks.
 * Added XMP XML extraction for the following formats: GIF (untested), JPEG, TIFF, PNG, PSD.
 * Added RELEASE_NOTES file (this file).
 * Added Apache license header to bin.xml and src.xml Maven assembly descriptors.
 * Added Javadocs to the binary distribution
 

Release 0.94
------------

First Apache release of Sanselan.

Fixed bugs:
-----------
 * Can't convert PNG image to GIF image
    The PNG reader wasn't handling the 16-bit mode 4 PNGs properly. 
    The PNG reader wasn't gamma-correcting non-palette values properly in PNGs.
