-Microsoft Developer Studio Project File, Format Version 7.10 for libpng.
-
-Copyright (C) 2004 Simon-Pierre Cadieux.
-
-This code is released under the libpng license.
-For conditions of distribution and use, see copyright notice in png.h
-
-NOTE: This project will be removed from libpng-1.5.0.  It has
-been replaced with the "vstudio" project.
-
-Assumptions:
-* The libpng source files are in ..\..
-* The zlib source files are in ..\..\..\zlib
-* The zlib project file is in . /* Warning: This is until the zlib project
-  files get intergrated into the next zlib release. The final zlib project
-  directory will then be ..\..\..\zlib\projects\visualc71. */
-
-To use:
-
-1) On the main menu, select "File | Open Solution".
-   Open "libpng.sln".
-
-2) Display the Solution Explorer view (Ctrl+Alt+L)
-
-3) Set one of the project as the StartUp project. If you just want to build the
-   binaries set "libpng" as the startup project (Select "libpng" tree view
-   item + Project | Set as StartUp project). If you want to build and test the
-   binaries set it to "pngtest" (Select "pngtest" tree view item +
-   Project | Set as StartUp project)
-
-4) Select "Build | Configuration Manager...".
-   Choose the configuration you wish to build.
-
-5) Select "Build | Clean Solution".
-
-6) Select "Build | Build Solution (Ctrl-Shift-B)"
-
-This project builds the libpng binaries as follows:
-
-* Win32_DLL_Release\libpng15.dll      DLL build
-* Win32_DLL_Debug\libpng15d.dll       DLL build (debug version)
-* Win32_DLL_VB\libpng15vb.dll         DLL build for Visual Basic, using stdcall
-* Win32_LIB_Release\libpng.lib        static build
-* Win32_LIB_Debug\libpngd.lib         static build (debug version)
-
-Notes:
-
-If you change anything in the source files, or select different compiler
-settings, please change the DLL name to something different than any of
-the above names. Also, make sure that in your "pngusr.h" you define
-PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX according to the
-instructions provided in "pngconf.h".
-
-All DLLs built by this project use the Microsoft dynamic C runtime library
-MSVCR71.DLL (MSVCR71D.DLL for debug versions).  If you distribute any of the
-above mentioned libraries you may have to include this DLL in your package.
-For a list of files that are redistributable in Visual Studio see
-$(VCINSTALLDIR)\redist.txt.

-VisualStudio instructions
-
-libpng version 1.5.1 - February 3, 2011
-
-Copyright (c) 1998-2010 Glenn Randers-Pehrson
-
-This code is released under the libpng license.
-For conditions of distribution and use, see the disclaimer
-and license in png.h
-
-This directory  contains support for building libpng under MicroSoft
-VisualStudio 2010.  It may also work under later versions of VisualStudio.
-You should be familiar with VisualStudio before using this directory.
-
-Initial preparations
-====================
-You must enter some information in zlib.props before attempting to build
-with this 'solution'.  Please read and edit zlib.props first.  You will
-probably not be familiar with the contents of zlib.props - do not worry,
-it is mostly harmless.
-
-This is all you need to do to build the 'release' and 'release library'
-configurations.
-
-Debugging
-=========
-The release configurations default to /Ox optimization.  Full debugging
-information is produced (in the .pdb), but if you encounter a problem the
-optimization may make it difficult to debug.  Simply rebuild with a lower
-optimization level (e.g. /Od.)
-
-Linking your application
-========================
-Normally you should link against the 'release' configuration.  This builds a
-DLL for libpng 1.5 with the default runtime options used by Visual Studio
-2010.  In particular the runtime library is the "MultiThreaded DLL" version.
-If you use Visual Studio defaults to build your application you will have no
-problems.
-
-If you don't use the Visual Studio defaults your application must still be built
-with the default runtime option (/MD).  If, for some reason, it is not then your
-application will crash inside libpng15.dll as soon as libpng tries to read
-from a file handle you pass in.
-
-If you do not want to use the DLL, for example for a very small application,
-the 'release library' configuration may be more appropriate.  This is built
-with a non-standard runtime library - the "MultiThreaded" version.  When you
-build your application it must be compiled with this option (/MT), otherwise
-it will not build (if you are lucky) or crash (if you are not.)
-
-Stop reading here
-=================
-You have enough information to build a working application.
-
-Debug versions have limited support
-===================================
-This solution includes limited support for debug versions of libpng.  You
-do not need these unless your own solution itself uses debug builds (it is
-far more effective to debug on the release builds, there is no point building
-a special debug build.)
-
-The debug build of libpng is minimally supported.  Support for debug builds of
-zlib is also minimal.  You really don't want to do this.
