Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

You can use only one transparent color.

With formats that support alpha channel, use the alpha channel.

Description:
------------
In my php.ini file,
i enabled GD only.

ie) uncomment that one line for gd configuration


Reproduce code:
---------------
$logoImage is png image.
        $image1 = ImageCreateFromPNG($logoImage);
        $color=imagecolorat($image1,$mouseX,$mouseY);
        imagecolortransparent($image1,$color);
         ImagePNG($image1,"$logoImage");

after transparant a color in image. save that image .

what the problem is,
  after that i transparent another color in that image ,last color is
only
tranperant. previous color revoke it's original place.

for example :
     imagecolortransparent($image1,$color);
     imagecolortransparent($image1,$color1);
     imagecolortransparent($image1,$color2);
     imagecolortransparent($image1,$color3);


Expected result:
----------------
after excution only that image transperant for $color3
but i want a transparent image with all four color.
what can i do?
any other functions..


Actual result:
--------------
only image with last color transparancy.
