Dear Daman,


Thanks for your interest in Aspose.Slides.


Please use the code snippet below to get the slide thumbnails.


//Reading the PPTX file

PresentationEx pres = new PresentationEx("D:\\ppt\\Test.pptx");

//Accessing first slide of presentation

SlideEx slide = pres.Slides[0];

//Obtaining thumbnail of the slide

System.Drawing.Image imgThumbnail = slide.GetThumbnail(1f,1f);

//Saving the thumbnail to Jpeg

imgThumbnail.Save(@"d:\ppt\1.jpg");

System.Drawing.Image imgPreview = slide.GetThumbnail(1f, 1f);

//Saving the thumbnail to png

imgPreview.Save(@"d:\ppt\1.png");
