     10 As a PNG .dll demo VisualPng is finished. More features would only hinder
     11 the program's objective. However, further extensions (like support for other 
     12 graphics formats) are in development. To get these, or for pre-compiled 
     13 binaries, go to "http://www.schaik.com/png/visualpng.html".

     43 are available:
     44 
     45 1) Build the program with the configuration "Win32 LIB" and you only need to
     46    include the executable from the ./lib directory in your distribution.
     47 
     48 2) Build the program with the configuration "Win32 DLL" and you need to put
     49    in your distribution the executable from the ./dll directory and the dll's
     50    libpng1.dll, zlib.dll and msvcrt.dll.  These need to be in the user's PATH.
