-Installing libpng version 1.2.6 - August 15, 2004
+Installing libpng version 1.2.7 - September 12, 2004
Before installing libpng, you must first install zlib. zlib
can usually be found wherever you got libpng. zlib can be
version of zlib that's installed.
You can rename the directories that you downloaded (they
-might be called "libpng-1.2.6" or "lpng109" and "zlib-1.1.3"
-or "zlib113") so that you have directories called "zlib" and "libpng".
+might be called "libpng-1.2.7" or "lpng109" and "zlib-1.2.1"
+or "zlib121") so that you have directories called "zlib" and "libpng".
Your directory structure should look like this:
*.c
contrib
gregbook
- msvctest
pngminus
pngsuite
visupng
projects
beos
- borland
- msvc
+ c5builder (Borland)
+ visualc6 (msvc)
netware.txt
wince.txt

distribution of libpng. It is available in both tar.gz (UNIX style line
endings) and zip (DOS style line endings) formats.
-If you are building libpng with MSVC, you can enter the libpng\msvc directory
-and follow the instructions in msvc\README.txt.
-You can build libpng for WindowsCE by entering the downloading and installing
-the libpng\wince directory as instructed in the projects\wince.txt file, and
+If you are building libpng with MSVC, you can enter the
+libpng projects\visualc6 directory and follow the instructions in
+projects\visualc6\README.txt.

+You can build libpng for WindowsCE by downloading and installing
+the projects\wince directory as instructed in the projects\wince.txt file, and
then following the instructions in the README* files. Similarly, you can
-build libpng for Netware as instructed in projects\netware.txt.

changes.
