Hi,

We are working on a project where we need to identify the number of pages in a tif/pdf file from our .net application.

Please let me know how to proceed in this regard. One way to proceed is to use some third party tools for this purpose for for this project, we will not be able to use any external tools.

Thanks in advance
RS

1. private int GetTotalpages(string filePath)
2. {
3. int pageCount = 0;
4. using (FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read))
5. {
6. using (Image temp = Image.FromStream(fs))
7. {
8. pageCount = temp.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page);
9. }
10. }
12. return pageCount;
13. }
0

You can use LEADTOOLS Imaging SDK technology in your application.

Here is some sample code:

using (RasterCodecs codecs = new RasterCodecs())
{
string srcFile = @"FILE PATH TO TIFF OR PDF";
CodecsImageInfo info = codecs.GetInformation(srcFile, true);
Console.WriteLine($"TIFF image total pages: {info.TotalPages}");
}

As far as the multipage tif goes; you can do something like this to get the page count and to retrieve a single image:

using System;

using System.Collections.Generic;

using System.Text;

using System.Drawing;

using System.Drawing.Imaging;

using System.Windows.Forms;

using System.IO;

namespace MultiPageTiff

{

public class MultipageTiff

{

public int GetNumberOfPages(string sFileName)

{

//setup the image

Image img = Image.FromFile(sFileName);

//get its guid

Guid ID = img.FrameDimensionsList[0];

//get the frame dimensions

FrameDimension fd = new FrameDimension(ID);

//Gets number of pages

return img.GetFrameCount(fd);

}

public Image GetSpecificPage(string sFileName, int iPageNumber)

{

Image img = Image.FromFile(sFileName);

MemoryStream ms = null;

Image returnImage = Image.FromFile(sFileName);

try

{

ms = new MemoryStream();

Guid ID = img.FrameDimensionsList[0];

FrameDimension fd = new FrameDimension(ID);

img.SelectActiveFrame(fd, iPageNumber);

img.Save(ms, ImageFormat.Bmp);

returnImage = Image.FromStream(ms);

return returnImage;

}

catch (Exception ex)

{

MessageBox.Show(ex.Message.ToString(), "Error");

return null;

}

finally

{

ms.Close();

}
