Description

The function scales the coordinate system by applying a transformation matrix.
It is highly recommended to save the graphics state beforehand, otherwise it is very difficult or impossible to restore the coordinate system later.
After scaling the coordinate system, bottom-up coordinates are active. It is not possible to use top- down coordinates inside a scaled coordinate system.
Please do not try to scale/skew/translate back later. use DynaPDF.SaveGraphicState and DynaPDF.RestoreGraphicState.

See also ScaleCoords function in DynaPDF manual.
