-===== Building LibPng 1.2.29 =====+===== Available prebuilt libraries =====
  
 +All prebuilt libraries are available in the php-libs [[http://windows.php.net/downloads/php-sdk/|repositories]]
 +
 +For PHP suitable sources and up-to-date information see [[https://github.com/winlibs/libpng]]
 +
 +The filename format is:

 +libpng-x.y.z-vcversion-asm.zip
 +
 +where x.y.z defines the version, vcversion which Visual C++ has been used and -asm tells if the ASM optimizations have been used or not (see the options below).
