资源说明：Experimental image compression tool based on adaptive hp-FEM
================ Welcome to HIMG! ================ HIMG is an experimental image compression code based on adaptive higher-order finite element methods (hp-FEM). It is built upon the Hermes2D library (http://hpfem.org/hermes2d). Usage ===== First install HIMG as described below. In Linux, set the PYTHONPATH variable to where your _hermes_common.so library is, and then (on Linux) type ./run squares In addition to "squares" you can also try "diag", "lena", and "sat". In MSVC, use the MSVC IDE. Set the command line parameters to ``-i ../img/squares/squares.ppm`` and run the application HIMG.

Download and Installation ========================= Installation instructions for Linux and Windows MSVC can be found in the Sphinx documentation at http://hpfem.org/himg/doc/index.html. Documentation ============= Generating and Viewing User Documentation Offline (Linux) --------------------------------------------------------- Source files of the (Sphinx) user documentation are in the directory doc/. In order to compile the user documentation, you need to install Sphinx. Then follow these steps: cd doc make html firefox _build/html Generating and Viewing User Documentation Offline (Windows+MSVC) ---------------------------------------------------------------- This is a sequence of steps which will install Sphinx and which will allow to generate user documentation. The steps assume that you have already installed Microsoft Visual Studio 9 (MSVC) Express Edition (or any higher edition) and you have a copy of HIMG sources. All commands, which are marked with a keyword 'prompt:', are executed in a command prompt opened in the step 3. Search for all mentioned application through Google since, usually, the first link is the right one. 1) Download and install python 2.6 2) Add paths 'my_python_path\' and 'my_python_path\Scripts' to the enviromental variable PATH. 3) Open a command prompt with MSVC variables: Search for 'Visual Studio 2008 Command Prompt' in the start menu. 4) Download and install setuptools 0.6c11 5) Install Sphinx using setuptools (Internet access required) prompt: easy_install -U Sphinx 6) Go to a folder doc folder of HIMG source tree prompt: cd my_himg\doc 7) Run NMAKE requesting HTML version prompt: nmake html 8) View the documentation using a file 'my_himg\doc\_build\index.html' Generating and Viewing Developer Documentation Offline (Linux) -------------------------------------------------------------- Source files of the (Doxygen) developer documentation are in the directory doc.cpp/. In order to build them you need to install Doxygen. Then do: cd doc.cpp/ doxygen himg.lib.doxyfile This will generate documentation for the library. To view the docs, type firefox himg/html/index.html
