Installing libpng version 1.2.9beta1 - February 21, 2006
Installing libpng version 1.2.9beta2 - February 22, 2006
Before installing libpng, you must first install zlib. zlib
can usually be found wherever you got libpng. zlib can be
placed in another directory, at the same level as libpng.
Note that your system might already have a preinstalled
zlib, but you will still need to have access to the
zlib.h and zconf.h include files that correspond to the
version of zlib that's installed.
On Unix/Linux and similar systems, you can simply type
./configure [--prefix=$HOME]
make check
make install
and ignore the rest of this document.
Or you can use one of the custom-built makefiles in the
"scripts" directory
cp scripts/makefile.system makefile
make test
make install
Or you can use one of the "projects" in the "projects" directory.
Before installing libpng, you must first install zlib, if it
is not already on your system. zlib can usually be found

If your system already has a preinstalled zlib you will still need
to have access to the zlib.h and zconf.h include files that

You can rename the directories that you downloaded (they
might be called "libpng-1.2.9beta1" or "lpng109" and "zlib-1.2.1"
might be called "libpng-1.2.9beta2" or "lpng109" and "zlib-1.2.1"

Y2K compliance in libpng:
=========================
February 21, 2006
February 22, 2006
Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
upward through 1.2.9beta1 are Y2K compliant. It is my belief that earlier
upward through 1.2.9beta2 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has three year fields. One is a 2-byte unsigned integer

// Important note about DLL memory management when your DLL uses the
// static version of the RunTime Library:
//
// If your DLL exports any functions that pass String objects (or structs/
// classes containing nested Strings) as parameter or function results,
// you will need to add the library MEMMGR.LIB to both the DLL project and
// any other projects that use the DLL. You will also need to use MEMMGR.LIB
// if any other projects which use the DLL will be performing new or delete
// operations on any non-TObject-derived classes which are exported from the
// DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
// EXE's to use the BORLNDMM.DLL as their memory manager. In these cases,
// the file BORLNDMM.DLL should be deployed along with your DLL.
//
// To avoid using BORLNDMM.DLL, pass string information using "char *" or
// ShortString parameters.
//
// If your DLL uses the dynamic version of the RTL, you do not need to
// explicitly add MEMMGR.LIB as this will be done implicitly for you

// Important note about DLL memory management when your DLL uses the
// static version of the RunTime Library:
//
// If your DLL exports any functions that pass String objects (or structs/
// classes containing nested Strings) as parameter or function results,
// you will need to add the library MEMMGR.LIB to both the DLL project and
// any other projects that use the DLL. You will also need to use MEMMGR.LIB
// if any other projects which use the DLL will be performing new or delete
// operations on any non-TObject-derived classes which are exported from the
// DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
// EXE's to use the BORLNDMM.DLL as their memory manager. In these cases,
// the file BORLNDMM.DLL should be deployed along with your DLL.
//
// To avoid using BORLNDMM.DLL, pass string information using "char *" or
// ShortString parameters.
//
// If your DLL uses the dynamic version of the RTL, you do not need to
// explicitly add MEMMGR.LIB as this will be done implicitly for you
