\section intro_sec Introduction
The SDL2_gfx library provides the basic drawing functions such as lines,
circles or polygons provided by SDL_gfx on SDL2 against renderers of SDL2.
The current components of the SDL2_gfx library are:
- Graphic Primitives (SDL2_gfxPrimitives.h, SDL2_gfxPrimitives.c)
- Surface Rotozoomer (SDL2_rotozoom.h, SDL2_rotozoom.c)
- Framerate control (SDL2_framerate.h, SDL2_framerate.c)
- MMX image filters (SDL2_imageFilter.h, SDL2_imageFilter.c)
- Build-in 8x8 Font (SDL2_gfxPrimitives_font.h)
Note that SDL2_gfx is compatible with SDL version 2.0 (not SDL 1.2).
\section install_sec Installation
\subsection unix Unix/Linux
Use the standard autoconf/automake sequence to compile and install the library.
\verbatim
./autogen.sh # (optional, recommended)
./configure
make
make install
\endverbatim
\\subsubsection nommx Linker Configuration
The default location for the installation is /usr/local/lib and /usr/local/include.
This libary path may need to be added to the file the linker configuration file:
\verbatim
vi /etc/ld.so.conf
ldconfig
\endverbatim
\\subsubsection nommx Non-MMX Platforms
To build without MMX code enabled (i.e. ARM, PPC, AMD64 architectures):
\verbatim
./configure --disable-mmx
make
make install
\endverbatim
\subsection visualstudio Windows (VS2015)
Open the SDL2_gfx.sln solution file, right click on the solution and choose 'Rebuild'.
The SDL2-2.0.5 folder must be placed in a directory alongside SDL2_gfx (or sdl2gfx-code) and build in the same configuration, i.e. Debug or Release, beforehand so the referenced SDL2.lib file can be found.
\subsection platformosx Mac OSX
The usual autotools build chain should be used. MacPorts or fink may be required.
Xcode is supported via templates. See Xcode.zip - this template only supports SDL2_gfx
and not the tests. For this template, the Deployment Target (the lowest version to run on)
is set to 10.11 and expects the SDL2.framework preinstalled in the default location: /Library/Frameworks.
\section test_sec Test Programs
Change to the ./test directory and run
\verbatim
./autogen.sh
./configure
make
\endverbatim
to create several test programs for the libraries functions. This requires
the SDL2_gfx library to be previously compiled and installed.
See the source in the test/*.c files for some sample code and implementation hints.
\section documentation_sec Documentation
Please refer to the Doxygen-generated API documentation found in the
Docs/html folder as well as the test programs in the test folder.
