[PHP-DEV] Bug #12963 Updated: ImageColorAllocate() doesn't work with PNGs From: wez <email protected>
Date: 08/27/01

ID: 12963
Updated by: wez
Reported By: perry <email protected>
Status: Feedback
Bug Type: GD related
Operating System: Windows95
PHP Version: 4.0.6
New Comment:

PHP 4.0.6 on win32 uses GD 2.0.1 BETA.
It is broken for palette based PNG images; you
need to use a different version of GD, or wait for PHP 4.0.7.

I'm not a PNG expert but you could try ImageColorResolve()
The palette used in 'basic.png' may be different than you
expect.

<?php
header ("Content-type: image/png");
$text=implode($argv," ");
$image=imageCreateFromPNG("basic.png");
$background_color = ImageColorAllocate ($im, 100, 100, 255);
$text_color=imageColorAllocate($image,255,100,100);
$textX=(imageSX($image)-imageFontWidth(4)*strlen($text))/2;
imageString($image,5,$textX,10,$text,$text_color);
imagePNG($image);
imageDestroy($image);
?>
    
This is only a small modification of the example given in the manual, but the $text_color is always white.

This works for JPEG, but the quality suffers, and my build of PHP doesn't support GIF's.
