Hello I am trying to combine two transparent png-24 images, both size 400width, 150height.
A background: ["http://www.fenixflame.net/Background-Zanaris-24.png"][1]
And the image I want to overlay adobe the background: ["http://www.fenixflame.net/Bandos-Slayer-24.png"][2]
I've tryed overlaying transparent images using php but only png-8 images. Can't use png-8 beacause the images just don't render correctly.
Edit: Code I've tryed:
$image = imagecreatefrompng("http://www.fenixflame.net/Background-Zanaris-24.png");
$frame = imagecreatefrompng("http://www.fenixflame.net/Bandos-Slayer-24.png");
//
//imagealphablending($frame,true);
//
$insert_x = imagesx($frame);
$insert_y = imagesy($frame);
imagecopymerge($image,$frame,0,0,0,0,$insert_x,$insert_y,100);
//
//# Save the image to a file imagepng($image, '/path/to/save/image.png');
imagepng($image, "/home1/fenixfl开发者_运维问答a/public_html/Images/Signatures/NewImageBG.png");
//
//# Output straight to the browser.
imagepng($image);
//
I have write a small example to merge two transparent image in this link scitam.com
try this code it works fine.
$width = 200; $height = 200; $base_image = imagecreatefromjpeg("base.jpg"); $top_image = imagecreatefrompng("top.png"); $merged_image = "merged.png"; imagesavealpha($top_image, true); imagealphablending($top_image, true); imagecopy($base_image, $top_image, 0, 0, 0, 0, $width, $height); imagepng($base_image, $merged_image);
Use GD Library to render the image and output it in php. http://www.php.net/manual/en/ref.image.php
It gets pretty hairy after that. You have to use start doing things like
imagealphablending($image, false);
imagesavealpha($image, true);
and so on to make sure transparency is correct.
you can see an example of what I did for a client way back on their front page here. It was super tedious and a huge pain. Have fun
How about using lib ImageMagick composite (http://www.imagemagick.org/script/composite.php)
function composite() {
$command = "/usr/local/bin/composite [... your properties...]";
exec($command, $output, $result);
return ($result == 0 && $output[0] == "");
}

The imagecopymerge function is part of the PHP GD library.
