Member variable XbpPresSpace():mode Foundation
Adjusts precision of graphic output
The instance variable is used to adjust the output precision of Gra..() functions. This can be necessary for scaled graphic output caused by a changed viewport or a transformation matrix, for example. With normal precision it is possible that scaled output does not appear at the exact position and/or size in the device context. If this is the case, the drawing precision must be raised to a higher level.
#define constants listed in GRA.CH must be used for this instance variable.
