- ------------------------------------------------------------------------
- Copyright 2000, Willem van Schaik. For conditions of distribution and
- use, see the copyright/license/disclaimer notice in png.h
- 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".
- ------------------------------------------------------------------------
- Assumes that
- libpng DLLs and LIBs are in ....projectsmsvcwin32libpng
- zlib DLLs and LIBs are in ....projectsmsvcwin32zlib
- libpng header files are in ......libpng
- zlib header files are in ......zlib
- the pngsuite images are in ..pngsuite
- 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.
