---------------------------------------------------------------------------------------- CHANGES.txt : List the changes made between consecutive versions of The CImg Library ----------------------------------------------------------------------------------------- *----------------------------- *----------------------------- * Changes from 1.3.0 to 1.3.1 *----------------------------- *----------------------------- * New features : - Added configuration macro 'cimg_file_separator' that takes value "/" or "\" depending on which OS is running. This macro is used in load/save functions for better portability. - New example file 'examples/gaussian_fit.cpp' which demonstrates how to apply the Levenberg-Marquardt algorithm to fit a 3-parameter gaussian on a set of sample points. - Added function 'CImg[{Display,List}]::empty()' that returns a reference to an empty object (can be used to pass empty images as default values of function parameters). - Added variant of the function 'CImg<T>::draw_triangle()' to draw triangle with linearly interpolated colors defined at each triangle vertex. - Added a formula parser in CImg<T>, so that many arithmetic operators can use it to evaluate expressions (given as a C-string). - Added example file 'examples/plotter.cpp' that plots a mathematical function on an interactive window. - Added functions 'CImg<T>::index()' and 'CImg<T>::map()' that can index an image with a multi-spectral palette, or map a multi-spectral palette on an image. * Optimizations / Modifications : - Added parameter 'bytes_per_pixel' to force the use of 8 or 16 bits modes in functions 'CImg<T>::save_magick()', 'CImg<T>::save_pnm()' and 'CImg<T>::save_png()'. Thanks to Julien Morat for pointing this out to me. - Added parameter 'backward' to 'CImg<T>::displacement_field()', allowing to select between forward of backward estimation procedure. - Parameters 'ru,rv' in 'CImg<T>::draw_ellipses()' have been replaced by parameter 'angle'. - Function 'CImg[List<T>]::get_split()' is now able to split an image into bloc of given pixel size. - Changed 'zbuffer' parameter type to 'CImg<float>' in 'CImg<T>::draw_*' functions. - Remove 'GREYCstoration' specific code. The GREYCstoration algorithm is now a part of the G'MIC framework. Note that the two functions 'CImg<T>::blur_anisotropic()' and 'CImg<T>::blur_patch()' are still here to smooth an image anisotropically (are the core algorithm of the former GREYCstoration). * Bug corrections : - Corrected 'CImg<T>::translate()' : function parameters were the opposite of the real translation done. - Modifications on CImg.h to be more compatible with the old VC++6 compiler. - Corrected 'CImg<T>::get_histogram()'. - Corrected 'CImg<T>::load_ascii()'. - And lot of small bugs corrections. *----------------------------- *----------------------------- * Changes from 1.2.9 to 1.3.0 *----------------------------- *----------------------------- The 1.3.0 version of the CImg Library is a major release, and will probably break the compatibility with your existing code. Anyway, the overall philosophy is the same so converting your code should not require lot of work fortunately. * New features : - Added function 'CImg<T>::[get_]distance()' that compute the Euler unsigned distance map from a shape of specified isovalue in an image, using a fast linear algorithm. - Added functions 'CImg<>::set_linear_at{X,Y,Z}()' allowing to set pixel values using float-valued coordinates, with linear interpolation. - Added z-buffering capabilities in some drawing functions, so that displaying a 3D object with 'CImg<T>::draw_object3d()' now takes care of eventual crossing primitives. (added shortcut CTRL+Z to enable/disable zbuffering in 'CImg<T>::display_object3d()'. - Added functions 'CImgList<T>::is_same*()' to check dimensions of image lists. - Added plugin 'plugins/skeleton.h', as well as example of use 'examples/skeletonize.cpp' that computes the skeleton of a shape (binary image). Thanks to F-X Dup� for this nice contrib ! - Added function 'CImg<T>::get_elevation3d()' that constructs a 3D object by 'elevating' an instance image. - In function 'CImg<T>::sharpen()', two sharpening methods are now implemented : shock filters and inverse diffusion. - Added function 'CImg[List]<T>::save_ffmpeg()', allowing to save an image sequence, directly as a movie file, using the FFMPEG library. Thanks to David. G. Starweather for this very nice contribution ! - Added function 'CImg<T>::[get_]warp()' that can warp an image using a deformation field. - Added function 'CImg<T>::[get_]solve_tridiagonal()' that can quickly solve a tridiagonal linear system of equations (use the Thomas Algorithm). - Added function 'CImg<T>::[get_]load_dcraw_external()' that allows to read RAW digital camera files, using the open-source external tool 'dcraw'. - Added file 'examples/CMakeLists.txt' to generate makefile using the 'cmake' tool (thanks to Baptiste Mougel for this nice contribution). - Added functions 'CImg<T>::display_graph()' and 'CImg<T>::select_graph()' that can be used to display a graph plot or crop a sub-graph. - Added function 'CImg<T>::[get_]autocrop()' that can autocrop an image regarding to a background value or color. - Added new demo 'Word Puzzle' in file 'examples/CImg_demo.cpp'. - Added new plugin 'plugins/cimgIPL.h', as well as example file 'examples/use_cimgIPL.h' that shows how to convert between CImg and IplImage structures (used in OpenCV). Thanks to Haibo Zheng for this nice contribution ! - Function 'CImg<T>::load_ffmpeg()' is now able to return information on the main video stream, without having to load frames. - New function 'CImg[List]<T>::valuestring()' returns a C-string containing values of the image pixels. - Added file 'examples/gmic4gimp.cpp' which implements a G'MIC plug-in for GIMP. - Added file 'resources/cimg_buildpackage' which is a bash script that generates package files for CImg. - Added function 'cimg::prand()' which returns a random variable following a Poisson distribution. * Optimizations / Modifications : - The API of the library has been quite largely modified. It means that the 1.3.0 release is not meant to be fully compatible with previous versions. This is the beginning of a new important branch. - Functions 'CImg[List]<T>::load()' can now check for magick numbers for determining file format (instead of using only their filename extension). - Cleaned lot of code in 'CImg<T>::draw_*()' functions. Few of them have now different signatures, particularly 'CImg<T>::draw_text()', 'CImg<T>::draw_spline()' and 'CImg<T>::draw_image()'. - Improved warning removal when compiling on Microsoft Visual C++ compiler. It is now very rare to get warnings when compiling CImg-based files ! - Plugin 'plugins/distance_saito.h' has been removed, since a new and clean implementation of the distance function is now available in the 'CImg.h' file. - Function 'CImg<T>::equalize_histogram()' has been renamed to 'CImg<T>::equalize()'. - Functions 'CImg<T>::get_gradient()', 'CImg<T>::get_structure_tensor()' and 'CImg<T>::get_hessian()' now replaces the old versions. - Provided example file 'examples/inrcast.cpp' has been renamed and recoded as 'examples/gmic.cpp'. G'MIC is now an independant project, having its own web page : http://gmic.sourceforge.net/. - Plugin 'plugins/cimgmatlab.h' has been updated. - Added pipe support (for POSIX systems) in load/sa
