Hi Aspose Team. I have one strange issue - the library generates wrong thumbnail of shape. I’m using the last version of library. Here you can find the archived sourcecode with sample presentation and generated thumbnail.

@obrusentsov,

Can you please use Shape.GetThumbnail(ShapeThumbnailBounds bounds, float scaleX, float scaleY) with ShapeThumbnailBounds.Appearance . It is used for cases when shape appearance doesn’t fit into the shape bounds. E.g. rotation, miter join of acute angle, etc. Can you please try to you following sample code on your end and share feedback with us if there is still an issue.

var pres = new Presentation(path + "wrong_shape.pptx");
foreach (ISlide slide in pres.Slides)
{
    foreach (IShape shape in slide.Shapes)
    {
        using (var thumbnail = shape.GetThumbnail(ShapeThumbnailBounds.Appearance, 1, 1))
        {
            thumbnail.Save(path + "ShapeAppearance.png");
        }
    }
}
