Getting page count for pdfs

Hi,

First of all, thanks for creating and maintaining this awesome framework!

I’m working on a project where we are using this framework to work with images and pdfs. The pdf operations in it self seems pretty easy, following your documentation:

https://github.com/dlemstra/Magick.NET/blob/master/Documentation/ConvertPDF.md

The problem or question I have to this, is that for pdfs with alot of pages in it, this operation takes forever.

So if I use the following code:

MagickReadSettings settings = new MagickReadSettings();
settings.Density = new Density(300);
using (MagickImageCollection i = new MagickImageCollection())
{
    i.Read(file, settings);
}

The read operation takes forever. 60 pages takes around 50 seconds.

What I am really interested in is actually just the page count and not so much all the extra information that I get for each page in the pdf.

If I run a similar query on the Imagemagick exe:

magick.exe indentify -verbose -ping file.pdf

then it takes only 5-6 seconds, which is a significant difference.

Is there a way or a trick with which I can speed this up?

Thanks in advance!

I used iTextSharp to get the number of pages.

var its = new iTextSharp.text.pdf.PdfReader( pdfFile );
var numberOfPages = its.NumberOfPages;

Could you open a new issue to request support for that? And feel free to include an suggestion of how the API should look like.
