ImageMagick or GhostScript: convert a multi-page TIFF to a multi-page PDF

Question

I need to convert a multi-page TIFF to a multi-page PDF. I have access to ImageMagick and GhostScript (in *nix environment). How do I do this? Thanks.

UPDATE

Answer 1

Use following code to generate multi page pdf from multi page tiff file:

$image) {
    $image->setImageFormat("pdf"); 
    $images->addImage( $image );
}

$images->writeImages($yourFileName.'.pdf', true);
