PNGJ: Release Notes & History
==============================================================================
Version 0.85 (1 April 2012)
- More robust Chunk management (ChunkGroup is now inside PngChunk; both PngReader and PngWriter have a ChunkList...)
- PngMetadata: both PngReader and PngWriter have an instance to deal with metadata (chunks) at high level. eg: setDpi()/getDpi
- Added sPLT chunk
- The test of all testsuite images now copies all chunks ok.
- Deprecated Pngwrite.writeRow(ImageLine), use better Pngwrite.writeRow(ImageLine,rown)
- remove PngReader.foundChunksInfo
Version 0.80 (28 March 2012)
- Roll back auto increment of ImageLine rownumber at writing. Define some new PngWrite.writeLine() methods with slight change in semantics
- Fix bad chunk-id in PngChunkITXT
Version 0.71 (March 2012)
- Full support for all Chunk types (bKGD CHRM ICCP ITXT TRNS ZTXT - some yet untested)
- ar.com.hjg.pngj.nosandbox is now empty: PngFileHelper is back to main jar
- Lossy compression ar.com.hjg.pngj.lossy - (very EXPERIMENTAL yet, undocumented, lots of rough edges)
Version 0.62 (Jun 2011)
-----------------------
- Added Javadocs
- Implemented ImageLineHelper.tf_palIdx2RGB()
- Several code and comment polishing
Version 0.61 (Jun 2011)
-----------------------
- Better PNG filter strategies (different filters in same writer).
- Fixed issue with compression level (zip stream), it had no effect before.
- More chunks implemented (cHRM , sRGB , sBIT)
- Restricted visibility of some methods/fields
Version 0.6 (May 2011)
-----------------------
- Full support for indexed and grayscale, with any bitdepth
- The only non supported PNG images are the interlaced now.
- Chunk management fully reimplemented. (package ar.hjg.com.png.chunks)
- Decouple google-appengine-unfriendy code in package
ar.com.hjg.pngj.nosandbox package. See PngFileHelper.
- Constructors PngReader/PngWriter now use streams. See factory methods
in ar.com.hjg.pngj.nosandbox.PngFileHelper if you want to use files.
- Added test images from PNG suite - see MirrorTest
- Polished code, translated some spanish comments
Version 0.2 (Apr 2011)
-----------------------
- Issue with extra trailing IDAT chunks fixed.
Version 0.1 (January 2009)
---------------------------
- Full reading/writing capabilities for truecolor formats: RGB/RGBA , 8 and 16 bpp
- Other formats: paletted and grayscale images implemented (almost no testing),
only with 8bitdepth resolution (1,2,4 bits not implemented).
- Palette handling: very rudimentary: PngReader only reads the raw chunk and
PngWriter -if applicable- writes it back.
- Special color transformations (ICC) : unvisible for the API. The chunks are
read and write 'raw'.
- Special chunks: limited support for Physical resolution (DPI) and textual chunks.
All other ancillary chunks are blindly read and write.
