问题


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:

It turns out that my test file was wrong (it didn't have multiple pages), which made me think my command was wrong. This seems to work for me: convert input.tif output.pdf


回答1:


Use a tool called tiff2ps from the tool set provided by libtiff:

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

Once you have the tiff in ps format, you can call ps2pdf to convert to pdf, which is part of the ghostscript package in most linux distributions.




回答2:


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

This should work, though there can be some issues.

I had a similar situation of converting a multipage TIFF file. but in my case the resulting extension was JPG thumbnail. However, I believe that this following code will run for converting TIFF to 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();
}
?>

#THE ANSWER TO THE QUESTION IS THE TWO-PASS COMMANDS BELOW "convert" and "gs"
#THE CONVERT COMMAND COMBINES ALL THE TIFFS IN THE DIRECTORY INTO A SINGLE PDF
#THE GS (GHOSTSCRIPT) COMMAND RESIZES TO 8.5X11 AND COMPRESSES

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

<?php

$images = new Imagick($pathToYourFile);

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

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

?>
