Sets the coordinate system origin.
The native coordinate system of the Portable Document Format is bottom-up. However, DynaPDF supports also top-down coordinates to make the usage of the library easier. Top-down coordinates are then converted to bottom-up coordinates by DynaPDF, the coordinate system in the PDF file will not be changed by this function.
When changing the coordinate system to top-down, the coordinate origin of text (font origin) will also be changed to the top-left corner (see also DynaPDF.SetFontOrigin()). If the coordinate system will be changed to bottom-up, the font origin is also changed to the down-left corner too.
Default value is BottomUp.
The property PageCoords is a global property which can be changed at any time. When transforming the coordinate system, bottom-up coordinates must be used.
