TPdfWriter.YAxisGrowsDown Property
When true, the y axis origin corresponds to the upper corner of a sheet and bigger Y coordinates will move down on the paper. This is the standard GDI+ behavior. When false, the Y origin is at the bottom and it grows up into the page. This is the standard PDF behavior.
