How to get PDF page dimensions

Question

I have an existing pdf and extracting text from the pdf. Here is the code I have already

using iTextSharp.text.pdf;
using iTextSharp.text.pdf.parser;
using System.IO;

public string ReadPdfFile(string fileName)
{
    StringBuilder text = new StringBuilder();

    if (File.Exists(fileName))
    {
        PdfReader pdfReader = new PdfReader(fileName);

        for (int page = 1; page <= pdfReader.NumberOfPages; page++)
        {
            ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
            string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);

            currentText = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(currentText)));
            text.Append(currentText);
        }
        pdfReader.Close();
    }
    return text.ToString();
}

I would like to get the dimensions of the pdf page. I need the dimensions so I can create a wrapper class that contains this information. Then the class can determine if rectangles are out of bounds.

Solution 1

I would like to get the dimensions of the pdf page.

The PdfReader class supplies methods to retrieve them:

PdfReader pdfReader = new PdfReader(fileName);

Rectangle mediabox = pdfReader.GetPageSize(pageNr);
Rectangle cropbox = pdfReader.GetCropBox(pageNr);

Depending on which dimensions you actually need, use either of those.

Solution 2

how about using this:-

PdfReader reader = new PdfReader(m);
PdfImportedPage page = writer.GetImportedPage(pdfReader, i);
// size information
page.PageSize.Width;
page.PageSize.Height;
