As a PNG .dll demo VisualPng is finished. More features would only hinder

the program's objective. However, further extensions (like support for other

graphics formats) are in development. To get these, or for pre-compiled

binaries, go to "http://www.schaik.com/png/visualpng.html".

   libpng DLLs and LIBs are in ..\..\projects\msvc\win32\libpng

   zlib DLLs and LIBs are in   ..\..\projects\msvc\win32\zlib

To build:



1) On the main menu Select "Build|Set Active configuration".

   Choose the configuration that corresponds to the library you want to test.

   This library must have been built using the libpng MS project located in

   the "..\..\mscv" subdirectory.



2) Select "Build|Clean"



3) Select "Build|Rebuild All"



4) After compiling and linking VisualPng will be started to view an image

   from the PngSuite directory.  Press Ctrl-N (and Ctrl-V) for other images.





To install:



When distributing VisualPng (or a further development) the following options

are available:



1) Build the program with the configuration "Win32 LIB" and you only need to

   include the executable from the ./lib directory in your distribution.



2) Build the program with the configuration "Win32 DLL" and you need to put

   in your distribution the executable from the ./dll directory and the dll's

   libpng1.dll, zlib.dll and msvcrt.dll.  These need to be in the user's PATH.
