This feature request has been implemented and is available in the latest versions of GemBox.Document.
Currently GemBox.Document supports PNG, JPEG, GIF, BMP, TIFF, WMF, and EMF image formats.
In the case of WMF and EMF vector image formats, when exporting them to PDF GemBox.Document will convert them to PNG, see the following help page:
Regarding the SVG, yes this format is currently not supported.
We currently do not have plans for it, so at the moment it will have to wait until its priority is increased (more user requests).
