// Map virtual paths to physical paths
string dataDir = Path.Combine(_env.ContentRootPath, inputDocxPath);
string physicalOutputPptxPath = Path.Combine(_env.ContentRootPath, outputPptxPath);

Please check the attached output file that we obtained using 24.3 version of the API in our environment with below code snippet.

using (Aspose.Pdf.Document document = new Aspose.Pdf.Document(dataDir + "ApprovedProjects (1).pdf"))
{
    Aspose.Pdf.PptxSaveOptions pptxSave = new Aspose.Pdf.PptxSaveOptions();
    pptxSave.SlidesAsImages = false;
    //pptxSave.OptimizeTextBoxes = true;
    pptxSave.TryMergeAdjacentSameBackgroundImages = false;
    //pptxSave.ImageResolution = 300; //192//300 // All three values are producing output with same file size and image quality
    document.Save(dataDir  + "output24.3.pptx", pptxSave);
}
