Issues with smart art and word art rendering

Hi we’re using Aspose.Cells for .NET version 7.7.2 and are having issues with the rendered images for smart art and word art contained in documents.

We are converting sheets to images and also extracting image individually from sheets but in both cases we are seeing considerable differences between the original shapes and the rendered ones.

As an example our Aspose.Cells code will loop over all shapes on a sheet and call ToImage() on the shape;

this.imageOptions.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;
this.imageOptions.Transparent = true;
this.imageOptions.ChartImageType = System.Drawing.Imaging.ImageFormat.Png;

foreach (Aspose.Cells.Drawing.Shape shape in sheet.Shape)
using (MemoryStream memoryStream = new MemoryStream())
shape.ToImage(memoryStream, this.imageOptions);
// Use the stream…

I’ve attached two documents which both display the rendering issue. The word art renders seem to loose all font formatting, and the results from the smart art is mixed but includes missing text, missing shapes and badly aligned images.

Are you able to confirm that this is an issue with the Aspose.Cells library or is there some other way I can be extracting images to solve this?
