thank you guys for your answers.
Luiz, your code-conversion for rsvg is exactly what I was looking for.
Now I can include the rsvg library and compile under lazarus. Unfortunately I can not get the function "rsvg_handle_new_from_file" to work properly.
In an code example based on code of your "RsvgClasses.pas" unit, the function "rsvg_handle_new_from_file" always returns NULL. I did not find a way to interpret the error codes neither.
Maybe someone has an idea what could be the problem and how to solve it.
thanks to all of you,
best regards, Philipp
