Problems with setting margin/indent on Apache fop PDF creation

Hello,

I'm using Apache fop 2.1 on an OpenSuse 15 SP 3 system.

We are creating a PDF document and have problems to set the rigth properties for page size, indent and margin.

We try to set the properties via calls to xmlSetProp() from lbxml2. It doesn't seem to have any effect, only if I use complete nonsense values, I get an error message.

The whole is a C++ program.

Any kind of help would be appreciated.

Kind regards,

Ralf Steckel
