I'm using Aspose.NET Cells for opening and saving an entire Excel Workbook to a TIFF image file. I'm currently looping through each Worksheet and calling the SheetToImage method. I was thinking it would append to the previous image but it's not - it's overwriting it.
I need to be able to save an entire Workbook, every page in every Worksheet, out to a single, multi-paged TIFF image.
How do I do this?
