Its often useful to search both the wiki and the forum, I just found a number of potential useful hits doing just that, 'svg'.

There is an example buried down in your Lazarus dir that talks about displaying an SVG in a PDF, I'd expect the process would be somewhat similar.

components/cairocanvas/example/cairoprog.lpr

Give those a try and come back with specific questions here if necessary. Generally, specific questions that start with "I tried XXX but YYY happened" get some pretty answers !

Have a look at https://forum.lazarus.freepascal.org/index.php?topic=36910.0 (it came up from a google search for "lazarus svg". It does not use "RSVG" though (it uses BGRABitmap).

cheers

Are you aware that all caps is regarded as shouting ?  I'll assume you are not so aware.

My post suggested you search the wiki and forum before asking you specif question. Did you ?

In the forum, I found over 200 hits for 'svg', a small number are likely to hold the key to your problem. Did you look through them ?  Pick out one or two that looked promising, maybe mention the ones you tried out. Then you could format your question in the manner I suggested.
