Issue with IPPImage.ReplaceImage Method when Using Aspose.Slides in C#

Aspose.Slides Product Family

Hi,
I’m having a problem with IPPImage.ReplaceImage method. When testing with an input .ppt file containing an external image that is grouped, Aspose.Slides.Presentation.Images.Count = 2.
After using IPPImage.ReplaceImage method and save to the outputFile, I checked the outputFile and the Aspose.Slides.Presentation.Images.Count = 3.

Sample code:

string inputFile = "D:\\external_image_grouped.ppt";
string outputFile = "D:\\external_image_grouped_out.ppt";
string sampleImage = "D:\\sample_image.jpg";
using (var inputStream = new FileStream(inputFile, FileMode.Open,
FileAccess.Read, FileShare.ReadWrite))
{
    int retVal = 0;
    Presentation inputPresentation = new Presentation(inputStream);

    var count = inputPresentation.Images.Count;  // count = 2
    foreach (var tmp in inputPresentation.Images)
    {
        var image = File.ReadAllBytes(sampleImage);
        tmp.ReplaceImage(image);
    }

    inputPresentation.Save(outputFile, SaveFormat.Ppt);
}

using (var outputStream = new FileStream(outputFile, FileMode.Open,
FileAccess.Read, FileShare.ReadWrite))
{
    int retVal = 0;
    Presentation outputPresentation = new Presentation(outputStream);
    var count = outputPresentation.Images.Count; // count = 3
}

Here is the sample file that I created to test external_image_grouped.zip (27.8 KB)

Please help me check and investigate the problem.

Thank you.

Hi @andrey.potapov,
Thank you for your response.

Here is my information:

  • .NET 5.0
  • Aspose.Slides version 21.2.0

I tried to upgrade to Aspose.Slides for .NET ver 23.1.0 and this problem is still not fixed.

I’ve checked again and edited the above sample file. It is my mistake when attaching the file.

So, could you please reproduce again with a new sample external_image_grouped.zip (27.8 KB)
