Hi,
Thanks for your inquiry.
First, sorry our Spire.Doc doesn’t support adding SVG image into a word document at present, we have added it as a new feature into our upgrade list with the ticket number SPIREDOC-3599. Once it is available in the future, we will let you know.
Second, we process images using system.Image and System.Bitmap, which encapsulate MS’s GDI + library (
https://learn.microsoft.com/en-us/windows/win32/gdiplus/-gdiplus-gdi-start), Spire.Doc supports the formats that GDI+ supports, including BMP、GIF、EXIF、JPG、PNG and TIFF .
Third, we will add the higher version like Docx2016 in FileFormat enum with the ticket number SPIREDOC-8280. When it is achieved in the future, I will inform you.
If you have any other questions, just feel free to contact us.
Sincerely,
Triste
