Can someone help me with the process to convert an array of tiff image paths to a PDF file? Here is the MagickWand code I was using...

Code: Select all

	function savePagesAsPDF($pages, $saveAs='temp.pdf')
	{
		if ($pages)
		{
			$w = NewMagickWand();
			MagickAppendImages($w);

			foreach ($pages as $p)
			{
				MagickReadImage($w, $p);
				// Convert image to jpg compression (otherwise it will convert jpgs to tifs and they will be HUGE)
				MagickSetImageCompression($w, MW_JPEGCompression);
				MagickSetImageCompressionQuality($w, 40); // 40% compression
			}

			MagickSetFormat($w, 'PDF' );
			MagickWriteImages($w, $saveAs, true);
		}
		return $saveAs;
	}

<?php

/* Create new Imagick object */
$im = new imagick( $pages );
$im->setFormat( 'PDF' );

$im->setImageCompression( Imagick::COMPRESSION_JPEG );
$im->setImageCompressionQuality( 40 );


$im->writeImages( 'temp.pdf', true );

?>

$im = new Imagick($pages);
$im->setFormat('PDF');
$im->setCompression( Imagick::COMPRESSION_JPEG );
$im->setCompressionQuality( 40 );
$im->writeImages($pdf, false);

then it will create 3 pdf files that look right, but then if I change the second parameter of writeImages to true, it creates that problem. I'm wondering if this is a bug in the interface...
