## Remarks
 This class is abstract, so you cannot instantiate it. It is used in inheritance tree of such classes as [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md) or [GdiGraphics](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Drawing_GdiGraphics.htm.md) to provide support of different units in method parameters.
