Usage: you can derive this class.
public class CATPrintGenerator
Base class to write generators and usually printer drivers.
Role: Derive from this class and override low-level methods to
generate drawing primitives in the desired language.
Printing is done through calls of high-level methods in user coordinates which
are in turn converted in low-level methods calls in device coordinates (note that
the unit is always the millimeter).
For instance, when plotting at scale 5, a high-level call :
generator->DrawLine(0, 0, 5, 10); // User coordinates
will be converted in the sequence
generator->DrvMoveTo(0, 0);
generator->DrvLineTo(25, 50); // Device coordinates
and so one, even for more complex operations (such as text discretization).
The following low-level methods must be overridden :
DrvBegin,
DrvEnd,
DrvFormFeed,
DrvDefineColor,
DrvSelectDrawColor,
DrvSetDrawWidth,
DrvMoveTo,
DrvLineTo,
DrvSelectFillColor,
DrvFillArea,
DrvDrawBitmap.
Whereas the following can be overridden if needed :
DrvDrawPolyline,
DrvDrawArcCircle,
DrvDrawArcEllipse,
DrvDrawPolyBezier,
DrvSetTextAttribute and
DrvDrawText.
