Hi,
If you are still wondering:
RS_Painter is only an abstract class, and you actually need RS_PainterQt( QPaintDevice* pd) derived from QPainter and RS_Painter.
For example, you can draw to a pixmap by something like:
QPixmap pixmap(1920, 1080);
RS_PainterQt painter(&pixmap);
gv->drawEntity(&painter, e);
