PDF Xtract is an enhancement of the PDF::Extract module. It is about 100 times
faster than PDF::Extract!
PDF Extract is a group of methods that allow the user to quickly grab pages
as a new PDF document from a pre-existing multi page PDF document.
With PDF::Xtract a new PDF document can be.
assigned to a scalar variable with getPDFExtract.
saved to disk with savePDFExtract.
These methods can be called with or without arguments. The methods
will not work unless they know the location of the original PDF document and the
pages to extract. There are no default values.
The following code can save paqges 1 to 10 and 15 from my.pdf to output.pdf.
use PDF::Xtract;
@pages=(1..10,15); $pages=\@pages;
$pdf = new PDF::Xtract( PDFDoc =>"/docs/my.pdf", PDFSaveAs="output.pdf", PDFPages =>$pages ) ;

HISTORY
-------
Fri Apr 15 21:15:17 IST 2005
Version 0.07
Trying to accelerate output generation, which seems to be the remaining bottleneck.
--------------------------------------------------
Thu Apr 7 15:02:22 IST 2005
Version 0.06
Noticed that Xtract fails with very large PDFs (>~500MB). It is now fixed by changing the way the file is read and
understood. Fringe benefit: module uses less memory than before. Additional variable is introduced: PDFReadSize,
specify the number of bytes to read at a time when reading the input file.
Documentation updated and corrected. Test script added to distribution.
--------------------------------------------------
Thu Mar 10 15:02:47 IST 2005
Noticed a problem with include objects! Work around done.
--------------------------------------------------
Wed Mar 9 10:50:35 IST 2005
No change in code, but making the distribution more acceptable for testing.
--------------------------------------------------
Thu Feb 20 15:02:47 IST 2005
Operational sequences within the module is being changed. New organisation will be as below:
Essentioal variable for doing anything is PDFDoc.
Extraction and making of document will run as and when PDFPages is defined. It will be generated into
the disk file named as PDFSaveAs if one exist, else will be taken to default extract file named as
$TempExtractFile.
Populating the PDFExtract is now secondary! If some one ask for that, we will return the content of the
file $TempExtractFile
--------------------------------------------------
Wed Mar 9 11:05:47 IST 2005
Version 0.03 : Just made the distribution more acceptale for CPAN testing.
--------------------------------------------------
Mon Feb 28 20:53:03 IST 2005
First beta release. (Version 0.02) Result of reworking Noel Sharrock's PDF::Extract when it was found
to be extreamly slow!
PDF::Xtract is at least 100 times faster than PDF::Extract in most cases.
