Hello,
I wan to use pdfbox in my project instead of the pdfl C adobe library.
For the task I have to calculate the width/height of the first page of the
document I used the following code:
PDDocument document = PDDocument.load(new File(args[0]));
PDPage pdPage = document.getPage(0);
System.out.println("PDFBOX - NoPage: " + document.getNumberOfPages());
Aystem.out.println("PDFBOX - FirstPage Height: " +
pdPage.getMediaBox().getHeight());
System.out.println("PDFBOX - FirstPage Width: " +
pdPage.getMediaBox().getWidth());
To obtain the same thing with pdfl I run I command line with some
parameters and read the response from a file, more ugly from java code.
But the performance is a big problem.
So with a 90MB pdf document I obtained a performance of 400millisec with
pdfbox and 50millisec with pdfl. For a 1.7GB document I obtained a
performace of 47106millisec with pdfbox and 151millisec with pdfl. These
are very big differences.
The main problem is that for accessing the first page I have to load the
entire document and after that I can access the first page.
PDFL has a constructor for a document with the page parameter and loads
only that page from the document. Because of that it is working so fast
Best regards,
Manuel.
