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
