  How to use: 1) require_once "gif_exg.php"; - include a library file

  2) $nGif = new GIF_eXG($source_file,$opt); - create an instance of the class

  • $source_file: full path to the source file
  • $opt: "1" - use optization "0" - not use optization (file will retain the internal structure)

  3) $nGif->resize($dest_file,$new_width,$new_height,$symmetry,$resampled); - public function for changing the size of (returns NULL on failure)

  • $dest_file: full path to the destination file
  • $new_width: new image width
  • $new_height: new image height
  • $symmetry: "1" - preserve symmetry "0" - not preserve symmetry
  • $resampled: "1" - use resampled "0" - not use resampled

  Example:

  require_once "gif_exg.php"; $nGif = new GIF_eXG("../image/src.gif",1); $nGif->resize("../image/dst1.gif",180,180,1,1); $nGif->resize("../image/dst2.gif",150,150,0,1);
