ImageMagick o GhostScript: converti un TIFF multipagina in un PDF multipagina

Question

Ho bisogno di convertire un TIFF multipagina in un PDF multipagina. Ho accesso a ImageMagick e GhostScript (in ambiente * nix). Come faccio a fare questo? Grazie.

UPDATE:

Si scopre che il mio file di prova era sbagliato (non aveva più pagine), che mi ha fatto pensare il mio comando era sbagliato. Questo sembra funzionare per me: convert input.tif output.pdf

Answer 1

Utilizzare uno strumento chiamato tiff2ps dal set strumenti forniti da libtiff:

http://www.libtiff.org/tools.html

volta che avete il tiff in formato ps, è possibile chiamare ps2pdf a convertirsi pdf, che fa parte del pacchetto ghostscript nella maggior parte delle distribuzioni Linux.

Answer 2

convert multipage.tiff -density 300x300 -compress jpeg multipage.pdf 

Questo dovrebbe funzionare, anche se ci possono essere alcuni problemi.

Answer 3

Ho avuto una situazione simile di conversione di un file TIFF multipagina. ma nel mio caso l'estensione risultante era una miniatura JPG. Tuttavia, credo che questo codice seguente verrà eseguito per convertire TIFF in PDF. http://sourcecodemania.com/how-to-convert-text-to-speech-with-php/

<?php 
try 
{ 
// Saving every page of a TIFF separately as a JPG thumbnail 
$images = new Imagick("testing.tif"); 
foreach($images as $i=>$image) { 
    // Providing 0 forces thumbnail Image to maintain aspect ratio 
    $image->thumbnailImage(768,0); 
    $image->writeImage("page".$i.".jpg"); 
    echo "<img src='page$i.jpg' alt='images' ></img>"; 
} 
$images->clear(); 
} 
catch(Exception $e) 
{ 
     echo $e->getMessage(); 
} 
?>

Usa seguente codice per generare più pagine PDF da più file di paging tiff:

<?php 

$images = new Imagick($pathToYourFile); 

foreach($images as $i=>$image) { 
    $image->setImageFormat("pdf"); 
    $images->addImage($image); 
} 

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

?>
