Question

我有一些PDF存储在数据类型为Image的SQL服务器中。现在我想从PHP页面将它们合并到一个带有Imagic的文档中。这是代码：

$combined   =   new Imagick();

while( $document    =   mssql_fetch_assoc( $mssqlResult ){
    $image      =   new Imagick(); 
    $image->readImageBlob( $document['Contents'] ) ;
    $combined->addImage( $image );
    $image->clear();
    $image->destroy(); 
}
$combined->setImageFormat("pdf");
$combined->writeImages( 'test.pdf', true );

这样做，并且test.pdf保存到服务器，但是当我尝试输出浏览器URL（类似http://www.test.com/test.php）时，它不起作用。代码是：

$combined   =   new Imagick();

while( $document    =   mssql_fetch_assoc( $mssqlResult ){
    $image      =   new Imagick(); 
    $image->readImageBlob( $document['Contents'] ) ;
    $combined->addImage( $image );
    $image->clear();
    $image->destroy(); 
}

//$combined->getImageBlob();

//$combined->setImageFormat("pdf");

//$combined->writeImages( 'test.pdf', true );

header('Content-type: application/pdf');

header('Content-Disposition: attachment; filename="test.pdf"');

echo $combined;

Answer 1

$combined   =   new Imagick();

while( $document    =   mssql_fetch_assoc( $mssqlResult ){
    $image      =   new Imagick(); 
    $image->readImageBlob( $document['Contents'] ) ;
    $combined->addImage( $image );
    $image->clear();
    $image->destroy(); 
}

$combined->getImageBlob();

$combined->setImageFormat("pdf");

$combined->writeImages( 'test.pdf', true );

header('Content-type: application/pdf');

header('Content-Disposition: attachment; filename="test.pdf"');

echo file_get_contents('test.pdf');

Answer 2

这有效：

combined   =   new Imagick();

while( $document    =   mssql_fetch_assoc( $mssqlResult ){
    $image      =   new Imagick(); 
    $image->readImageBlob( $document['Contents'] ) ;
    $combined->addImage( $image );
    $image->clear();
    $image->destroy(); 
}

$combined->setImageFormat("pdf");

header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="test.pdf"');
echo $combined->getImagesBlob();

请注意，关键字是getImagesBlob，而不是getImageBlob。

使用imagic和PHP输出PDF文件
