Bug description: Transparency is not working
Description:
------------
Transparency is not working on PNG files on W2K.
I've tried a few background colors, different formats, but can't get it
working.
Reproduce code:
---------------
<?php
// Example demonstrating a transparent truecolor png bug
// fixed by the time of gd 2.0.11, but not fixed in php's
// bundled gd.
header("Content-type: image/png");
$image = imageCreateTruecolor(640, 100);
$transparent = imageColorAllocate($image, 0, 0, 0);
$red = imageColorAllocate($image, 255, 50, 50);
imageColorTransparent($image, $transparent);
imageFilledRectangle($image, 0, 0, 640-1, 100-1, $transparent);
imageString($image, 3, 0, 0, "If the background is black, and you aren't
on win32 IE (buggy png code), this is a bug.", $red);
imagePng($image);
?>
Expected result:
----------------
The code should produce a white PNG image with red text.
Actual result:
--------------
The code produces a black PNG image with red text. The background is NOT
transparent.
