> It takes extremely long to render this file to image.
> Depends on computer but it can take 15s+ to render 1 page.
> When I skip drawing of inserted image /Im0, then rendering is fast. So there is something wrong with drawing that image in
> {code}
> PageDrawer.drawImage(Image awtImage, AffineTransform at)
> {code}
> when I comment out line 
> {code}
> graphics.drawImage(awtImage, imageTransform, null);
> {code}
> then rendering process takes 6s
