[RESOLVED] Create a horizontal panorama image from multiple images?

[curb]

How can I create one panoramic image from multiple images?

[NogDog]

Simplest way that comes to mind (assumes you have an array of image file names to be used):

<div style='white-space:pre;'><?php
foreach($imageName as $image)
{
   echo "<img src='$image' alt='' />";
}
?></div>

Nog dog's approach will display images left-to-right, but will not magically 'blend' the pictures to make one big seamless image. That's not really something that's easy to do. In fact, it sounds very difficult. I think you'd have to write an algorithm that examines a vertical stripe of pixels on the right side of an image and progressively compares them statistically to the vertical stripes of pixels starting from the left hand side of the next image until it finds a pretty decent match. Its' really involved.

Sorry for not making it clearer. I'm looking to have it saved as one panoramic image. Having it perfectly bend is fine as long as its side by side.

You need to read my post again. "having it perfectly blend" is a really difficult programming chore. The best you can hope for is to create an image that does not blend perfectly -- and that's not particularly simple either.

This will merge multiple images into one horizontal image. No attempt is made to blur or intelligently align them. Also note that if you are building up a large image, the total memory in bytes just for the resulting image needed by PHP while processing the script will be equal to 4 image_height image_width in pixels.

<?php
$images = array('image1.jpg', 'image2.jpg', 'image3.jpg');
$data = array();
$totalWidth = 0;
$maxHeight = 0;
foreach($images as $img) {
   $attr = getimagesize($img);
   $totalWidth += $attr[0];
   $maxHeight = max($maxHeight, $attr[1]);
   $data[] = array(
      'file' => $img,
      'attr' => $attr
   );
}
$panorama = imagecreatetruecolor($totalWidth, $maxHeight);
$counter = 0;
foreach($data as $img) {
   $frame = imagecreatefromstring(file_get_contents($img['file']));
   imagecopy(
      $panorama,
      $frame,
      $counter,
      0,
      0,
      0,
      $img['attr'][0],
      $img['attr'][1]
   );
   $counter += $img['attr'][0];
   imagedestroy($frame);
}
header('Content-Type: image/jpeg');
imagejpeg($panorama, null, 85);

Nice work, Nogdog.
