I hope someone has got solution for this:
I'm trying to write a script which will watermark a jpeg file with png logo,
and output the resulting jpeg to a file. Unfortunately, whatever I do, I'm
unable to get transparent color in png to disappear, by any means.
the png file is 8bit, jpeg is true color;
Am I doing something wrong? have a look:
<?
$sourcefile="test2.jpg";
$insertfile="peoplestamp.png";
$targetfile="test.jpg";
$transition=50;
$insertfile_id = imageCreateFromPNG($insertfile);
$sourcefile_id = imageCreateFromJPEG($sourcefile);
$sourcefile_width=imageSX($sourcefile_id);
$sourcefile_height=imageSY($sourcefile_id);
$insertfile_width=imageSX($insertfile_id);
$insertfile_height=imageSY($insertfile_id);
$dst = imageCreateTrueColor($sourcefile_width,$sourcefile_height);
imagealphablending($dst,TRUE);
imagecopy($dst,$sourcefile_id,0,0,0,0,$sourcefile_width,$sourcefile_height);
$aaa=imagecolorresolvealpha($insertfile_id,255,255,255,255);
imagecolortransparent($insertfile_id,$aaa);
imageCopyMerge($dst,
$insertfile_id,0,0,0,0,$insertfile_width,$insertfile_height,$transition);
imagepng ($dst,"$targetfile");
?>
<img src="<?=$targetfile?>" border=0>
Best regards,
