Adding a gif to a larger background - imagemagick

Question

I'm using imagemagick to resize uploaded files but while they're processing I want to show a rotating gif wheel to the user where the thumbnail would normally be. I serve about 7 sizes of thumbs and would like the wheel to remain at it's 32x32 size in the middle, that's the simple bit.
What I need to know is, can I do the above while still retaining the animation
Example:
This Image:
Starting at this size
With Animation

Answer 1

Check out this fiddle, it might contain what you want: http://jsfiddle.net/TGdFB/1/
It uses jQuery, but should be easily adaptable...

Answer 2

Ended up doing this manually by Photoshop after not being able to find an automated way of doing this through imagemagick. I found the 'coalesce' flag but not much else.

Answer 3

there is a solution in php witch i use to watermark gif animated images ....
it create an black bacground put an image on it and then put watermark ...
watermarkpath = 'path to wathermarkimage.jpg|gif|png';
$imagepath= 'path to the image';
$watermark = new Imagick($watermarkpath);
$GIF = new Imagick();
$GIF->setFormat("gif");
$animation = new Imagick($imagepath);
foreach ($animation as $frame) {
$iWidth = $frame->getImageWidth();
$iHeight = $frame->getImageHeight();
$wWidth = $watermark->getImageWidth();
$wHeight = $watermark->getImageHeight();
if ($iHeight < $wHeight || $iWidth < $wWidth) {
// resize the watermark
$watermark->scaleImage($iWidth, $iHeight);
// get new size
$wWidth = $watermark->getImageWidth();
$wHeight = $watermark->getImageHeight();
}
$bgframe = new Imagick();
$bgframe->newImage(($iWidth), ($iHeight + 80), new ImagickPixel('Black'));
$bgframe->setImageDelay($frame->getImageDelay());
$x = ($iWidth) - $wWidth - 5;
$y = ($iHeight + 80) - $wHeight - 5;
$bgframe->compositeImage($frame, imagick::COMPOSITE_DEFAULT, 0, 0);
$bgframe->flattenImages();
$bgframe->compositeImage($watermark, imagick::COMPOSITE_OVER, $x, $y);
$bgframe->flattenImages();
$GIF->addImage($bgframe);
}
$GIF->writeimages($imagepath,true);
