Hello,
Thanks for your quick response.
Yes, Spire.Office includes all our products, if you need to use spire.pdf,doc and XL in same project, you have to use Spire.Office, so you can refer to tutorials of our other products and apply same code/logic to use it.
Our Spire.Pdf product can support the feature to convert the image to pdf. The following link is for your reference.
