2012-08-30[trunk] STYLE: Clean up documentation errorsMickael Savinaud
Functions should only have formal documentation in one place, and preferably in the declaration (i.e. repeated documentaiton should not be at both the declaration and the definition, because it causes too much maintenance to keep them syncronized). In cases where the definition is also the declaration (as is often the case for static functions in the .c files) the documentation was preserved at the first use of the function signature. Functions that are formally documented should contain documentation for each function argument. The clang 3.1 compiler issues documentation warnings when the documentation block with @params preceeding a declaration does not match the argument list. This patch set follows a convention used elsewere in openjpeg to add a placeholder FIXME DOC description where one was previously missing. Thanks to Hans Johnson.

2007-12-10First import of JAVAOpenJPEG, a Java wrapper of OpenJPEG, developed by ↵Francois-Olivier Devaux
Patrick Piscaglia of Telemis (www.telemis.com). Thank you Patrick for this new module !
2007-11-27Fixed the maximum number of resolutions a user can discard while decoding.Francois-Olivier Devaux
Added an error state in J2K_STATE (j2k.c)
2007-11-14Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest ↵Francois-Olivier Devaux
allocations, because it contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate encode and decode versions. A lot of fields were not used by both, so this cuts its size even further.
2007-11-14Patch by Callum Lerwick. This patch rearranges the largest memory ↵Francois-Olivier Devaux
allocations so they're allocated as late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images.
2007-11-13Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which ↵Francois-Olivier Devaux
basically converts most of the irreversible decode codepath to floating point, eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement, and an increase in accuracy.
2007-10-18Patch from Callum Lewick. Memset patch. See ChangeLog for more details. ↵Francois-Olivier Devaux
Thanks Callum !
2007-10-12Changed the way the image structure is allocated when the decoding ↵Francois-Olivier Devaux
parameters include some resolutions to discard. This should have a significant impact for the decoding of huge images when some resolutions are discarder (-r parameter) Warning: The output image size is now reduced when discarding resolutions !
2007-09-18Fixed issues with Reading and Writing TIF images in convert.c to avoid ↵Parvatha Elangovan
segmentation fault. Fixed issues relating to using user specified rates for CINEMA option for multiple images.
2007-09-17Fixed issues with cstr_info when codestream has components with different ↵Francois-Olivier Devaux
number of resolutions.
