Hello,

I have an issue with powerpoint files saved in ppt (format 97-2003).

When I try to detect if a slide is hidden, library always answer that the slide is visible even if i's not the case.

Please find below sample code (c#) and ppt file enclosed (slide 2 is hidden in this ppt):

Code: Select all
byte[] fileContent = File.ReadAllBytes(@"C:\Temp\Presentation1.ppt");
using (MemoryStream ms1 = new MemoryStream(fileContent))
{
   Presentation presentation = new Presentation(ms1, FileFormat.Auto);

   for (int i = 0; i < presentation.Slides.Count; i++)
   {
      if (presentation.Slides[i].Hidden)
      {
         Console.WriteLine("Slide " + i + " is hidden");
      }
   ]
}


I tried to use all possible fileformat option without success.

It works fine with pptx (ppt 2013).

Spire presentation version: 2.7.51.9041

Thanks for your help,
Best regards,
Julien
