Question

How can I merge two images in PHP without GD?

Answer 1

PHP doesn't have the built in support to do what your asking. You'll need to
Execute another command line script/program that can
Install one of the many image manipulation libs and work with that
Possibly find a 3rd party API that you can send a request and get a response of the merged images?
Do as Emil suggested (Requires install: http://bg.php.net/manual/en/imagick.setup.php)

Answer 2

You can use Imagick.

Answer 3

You can't do image processing in PHP without some library like GD or ImageMagick.

Answer 4

i used this block of codes in my project to merge various images into one:
<?php
/* example invocation: http://www.yourserver.com/combine.php?dir=/images/ */
set_time_limit(5*60);
function sanitize($input) {
$input=strip_tags($input);
$input=str_replace("<","<",$input);
$input=str_replace(">",">",$input);
$input=str_replace("#","%23",$input);
$input=str_replace("'","`",$input);
$input=str_replace(";","%3B",$input);
$input=str_replace("script","",$input);
$input=str_replace("%3c","",$input);
$input=str_replace("%3e","",$input);
$input=trim($input);
return $input;
}
//accept path to images via http param dir (e.g. '/templates/corporate/images/okb/' -- include trailing slash)
$rel = '';
if (array_key_exists("dir", $_REQUEST)) $rel = sanitize($_REQUEST["dir"]);
if ($rel=='') die();
$rt = $_SERVER['DOCUMENT_ROOT'] . $rel;
$i = 0;
$imgBuf = array ();
$maxW=0; $maxH=0;
$imagesperline = 5;
$curlineW = 0;
$curlineMaxH = 0;
$imagespacing=5;
$dir = opendir ($rt);
while (false !== ($link = readdir($dir)))
{
$len = strlen($link);
$off = $len - 3;
$ext = substr($link, $off, 3);
$file = $rt . $link;
switch($ext)
{
case 'png':
$iTmp = imagecreatefrompng($file);
break;
case 'gif':
$iTmp = imagecreatefromgif($file);
break;
case 'jpeg':
case 'jpg':
$iTmp = imagecreatefromjpeg($file);
break;
default:
continue;
}
array_push ($imgBuf,$iTmp);
$i++;
if ($i == $imagesperline + 1)
{
$i = 0;
$maxW=($maxW>$curlineW)?$maxW:$curlineW;
$curlineW = 0;
$maxH+=$curlineMaxH+$imagespacing;
$curlineMaxH=0;
}
else
{
$ix = imagesx($iTmp);
$iy = imagesy($iTmp);
$curlineW+=$ix+$imagespacing;
$curlineMaxH=($iy>$curlineMaxH)?$iy:$curlineMaxH;
}
}
$iOut = imagecreate ($maxW,$maxH) ;
$i=1;
$curxpos = 0;
$curypos = 0;
$curlineMaxH=0;
foreach ($imgBuf as $img)
{
if ($i <= $imagesperline)
{
$ix = imagesx($img);
$iy = imagesy($img);
imagecopy ($iOut,$img,$curxpos,$curypos,0,0,$ix,$iy);
$curxpos+=$ix + $imagespacing;
$curlineMaxH=($iy>$curlineMaxH)?$iy:$curlineMaxH;
}
else
{
$i = 0;
$curxpos = 0;
$curypos += $curlineMaxH + $imagespacing;
$curlineMaxH = 0;
imagecopy ($iOut,$img,$curxpos,$curypos,0,0,$ix,$iy);
}
imagedestroy ($img);
$i++;
}
imagegif($iOut);
closedir ($dir);
?>
