I have png image with transparent background, and 1 jpg file.
I use imageCopyMerge to paste the png image on the jpg image.
the result image contain no transparent background mean the png file have white background when its suppose to be transparent
what is the simple and best way to make this work.
tanks in advance. :)
Libit:
I was working on the same thing. The following is a solution -- but, simple and best are relative.
This was taken from "PHP Graphics Handbook" by Kent et al.
<?
$original=imagecreatefromjpeg("apollo.jpg");
$watermark=imagecreatefrompng("xssportstransparent.png");
$osx=imagesx($original);
$osy=imagesy($original);
$wsx=imagesx($watermark);
$wsy=imagesy($watermark);
imagecopy($original, $watermark, ($osx-$wsx)/2, ($osy-$wsy)/2, 0, 0, $wsx, $wsy);
imagepng($original, "apollo_trans.png");
?>
<html>
<body>
<table>
<tr><td align=center>Orignal Image</td><td align=center>Watermark</td><td align=center>Orignal Image with Watermark</td></tr>
<tr><td><img src="apollo.jpg"></td><td><img src="xssportstransparent.png"></td><td><img src="apollo_trans.png"></td></tr>
</table>
</body>
