Question

我需要将多页TIFF转换为多页PDF。我可以访问ImageMagick和GhostScript（在* nix环境中）。我该怎么做呢？感谢。

更新

事实证明我的测试文件错误（它没有多个页面），这让我觉得我的命令错了。这似乎对我有用：convert input.tif output.pdf

Answer 1

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

这应该有效，但可能存在一些问题。

Answer 2

使用libtiff提供的工具集中名为tiff2ps的工具：

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

一旦你有ps格式的tiff，你可以调用ps2pdf转换为pdf，这是大多数Linux发行版中ghostscript包的一部分。

Answer 3

我有类似转换多页TIFF文件的情况。但在我的情况下，结果扩展名是JPG缩略图。但是，我相信以下代码将用于将TIFF转换为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 CONVERT COMMAND COMBINES ALL THE TIFFS IN THE DIRECTORY INTO A SINGLE PDF
#THE GS (GHOSTSCRIPT) COMMAND RESIZES TO 8.5X11 AND COMPRESSES

使用以下代码从多页tiff文件生成多页pdf：

<?php

$images = new Imagick($pathToYourFile);

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

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

?>
