hi,
we are using the following code to create thumbnails of slides.
int width = 800;
int height = 450;
using (IPresentation presentation = PresentationFactory.Instance.ReadPresentation(presentationStream))
{
ISlide firstSlide = presentation.Slides[0];
using (Bitmap bitmap = new Bitmap(width, height, PixelFormat.Format32bppArgb))
{
using (Graphics graphics = Graphics.FromImage(bitmap))
{
firstSlide.RenderToGraphics(false, graphics, width, height);
}
using (MemoryStream memoryStream = new MemoryStream())
{
bitmap.Save(memoryStream, ImageFormat.Png);
}
}
}
But the thumbnail for the attached presentation looks a little different from the slide, when the presentation is opened in Office 2016. Could you please help us to solve the problem? Thanks a lot!
Best Regards
Jeff
