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".

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.
