Version 1.5.1beta10 [January 27, 2010]
Fixed incorrect examples of callback prototypes in the manual, that were
introduced in libpng-1.0.0.
In addition the order of the png_get_uint macros with respect to the
relevant function definitions has been reversed. This helps the
preprocessing of the symbol files be more robust. Furthermore, the
symbol file preprocessing now uses -DPNG_NO_USE_READ_MACROS even when
the library may actually be built with PNG_USE_READ_MACROS; this stops
the read macros interfering with the symbol file format.
Made the manual, synopses, and function prototypes use the function
argument names file_gamma, int_file_gamma, and srgb_intent consistently.
Version 1.5.1beta11 [January 28, 2011]
Changed PNG_UNUSED from "param=param;" to "{if(param){}}".
Corrected local variable type in new API png_process_data_skip()
The type was self-evidently incorrect but only causes problems on 64 bit
architectures.
Added transform tests to pngvalid and simplified the arguments.
Version 1.5.1rc01 [January 29, 2011]
No changes.
Version 1.5.1rc02 [January 31, 2011]
Added a request in the manual that applications do not use "png_" or
"PNG_" to begin any of their own symbols.
Changed PNG_UNUSED to "(void)param;" and updated the commentary in pngpriv.h
Version 1.5.1 [February 3, 2011]
No changes.
* Fixed the build process for MacOS X.
* Re-activeted vigra-config (script to query VIGRA installation information)
and added VigraConfig.cmake (query VIGRA installation information from within
cmake).
* Added CDash support (nightly builds and tests).
* Added convexHull().
* Added vigra::Box.
* Added vigra::Sampler class to sample given data in various ways.
* Added much new functionality to the vigra::RandomForest class (e.g. more
split strategies, variable importance measures, feature selection)
* Added readSIF() (reader for the Andor SIF file format).
* Added vigra::HDF5File for easier navigation in HDF5 files.
* Added recursive approximation of the Gaussian filter
(recursiveGaussianFilterX(), recursiveGaussianFilterY())
* vigranumpy: added Gabor filtering.
* Fixed multi-threading bugs at various places.
* Minor improvements and bug fixes in the code and documentation.
