Re: [PHP] watermark png on jpg
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 trtd align=centerOrignal Image/tdtd align=centerWatermark/tdtd align=centerOrignal Image with Watermark/td/tr trtdimg src=apollo.jpg/tdtdimg src=xssportstransparent.png/tdtdimg src=apollo_trans.png/td/tr /table /body /html Demo at: http://xn--ovg.com/watermark HTH's tedd -- http://sperling.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I think this is on solution for this problem I found it the easy one. ah , one more thing, in my code I save the result image as an Jpg file. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
