How do I insert vector SVG into PDF

Q: I have a SVG image. I want to insert that SVG as vector element
(scalable etc) into PDF. (c++)

A: Unfortunately SVG can’t be embedded and displayed in PDF in its
native form. Some versions of Acrobat were partially supporting this
functionality, however it seems that since Adobe has stopped support
for SVG this functionality does not work. Therefore the only option is
to convert SVG to PDF. The upcoming version of PDFNet will support
conversion from SVG to PDF as part of HTML2PDF PDFNet add-on module
(which will be available on Jan 26.).
