I'm using Imagick lib to do some modifications to original image. Then I'd like to output it directly to browser without saving. Is there a way to do that?
I tried to use Imagick::writeImage('STDOUT') (empty output) and 'php://stdout' with error "Unable to write to file".
Any ideas? :)
You just need to echo your imagick object:
$img = new Imagick($file);
header('Content-Type: image/'.$img->getImageFormat());
echo $img;
If you're using HHVM it'll throw a fatal exception if you just try and echo the Imagick object so you'll need to call getimageblob();
$imagick = new Imagick('my-image.jpg');
header('Content-Type: image/' . $imagick->getImageFormat());
echo $imagick->getimageblob();
I believe what Schneck meant is:
header('Content-Type: '.$mime_type);
$fp = fopen('php://stdout', 'w+');
$image->writeImageFile($fp);
fclose($fp);
This may cause problems, especially in multipage files, so you should probably use:
ob_start();
$fp = fopen('php://output', 'w+');
$image->writeimagefile($fp); // or writeImagesFile for multipage PDF
fclose($fp);
$out = ob_get_clean();
header('Content-Length: '.strlen($out));
echo $out;
This is tested and working.
I realize this is an old question. The reason I'm posting this is that if you want to write a multipage PDF, this is the solution, as Nabab's solution only works for single images.
You can also use (PHP 5.1.0+):
$fp = fopen('php://temp', 'r+');
$image->writeimagesfile($fp);
rewind($fp);
$out = stream_get_contents($fp);
header('Content-Length: '.strlen($out));
fclose($fp);
echo $out;
This way seems to be faster if your PHP version supports it.
Before you downvote, the reason I added this as an answer and not a comment is I don't have sufficient reputation to comment. Hope that is alright. Just wanted to get this out there in case anyone needed it.
