Mathieu Malaterre cc01949777 The original v1.3 branch had: 
((int*)tiledp)[(j * tile_w) + i] = tmp / 2;
while v2 had:
((OPJ_INT32*)tiledp)[(j * tile_w) + i] = tmp >> 1;
Divide by two and a right shift operation are only equivalent when the data
is unsigned. In this case the data is signed, so the right shift operation
is incorrectly clearing the sign bit.

OPJViewer Minor style modifications to comply with c99 compiler flag; removed Microsoft-specific "union-in-struct" syntax; Re-enabled cstr_info struct creation when -W switch is specified. Changed a number of things in opjviewer (e.g., decoding thread does not execute GUI calls anymore), to have it running under linux --> it is better than before, but still crashes 2008-02-11 14:43:11 +00:00

README.v2 

Preliminary notes
-----------------

The Version 2 of openjpeg has been currently added as a branch on the repository. 

All the trunk has been copied and files that needed to change have been patched. In comparison with the trunk, the 'jp3d' directory has been removed because it's based on a modified version of libopenjpeg version 1 and there is no plan to make it reach the version 2 status. Idem with the 'indexer_JPIP', which is obsolete and should be rewritten from scratch.

At the time of the branch creation, the following files and directories have been updated (or added) for version 2 :
* libopenjpeg/
* codec/
* test_Free_image_V2_tile_handling/ : a test program that uses libopenjpeg v2 and libfreeimage (see libs) to implement a basic codec.
* test_V2_tile_handling/ : a test program that generates a random image and (de)compresses it with libopenjpeg v2.
* CMakeLists.txt
* Free_CMakeImport.cmake
* opj_configure.h.in

Other files and directories from the trunk (project files, jpwl/, OPJViewer/, ...) have also been copied in the branch and should be modified progressively to comply with v2. Check the Changelog for updates on this topic.

Enjoy v2 and feel free to contribute !
