double |
calculateMaxX(ITracePoint2D point)
Returns the maximum x bound this painter will need to paint the given
point.
|
double |
calculateMaxY(ITracePoint2D point)
Returns the maximum y bound this painter will need to paint the given
point.
|
double |
calculateMinX(ITracePoint2D point)
Returns the minimum x bound this painter will need to paint the given
point.
|
double |
calculateMinY(ITracePoint2D point)
Returns the minimum y bound this painter will need to paint the given
point.
|
protected void |
doDrawOperation(Graphics g2d,
int[] x,
int[] y,
int length)
Internally invokes the draw operation (to allow subclassing with a
different one).
|
void |
endPaintIteration(Graphics g2d)
Invoked to inform implementations that a paint iteration ends for the
corresponding
ITrace2D . |

boolean |
isAdditionalSpaceRequiredX()
Return true if this point painter needs more space in x dimension than
TracePoint2D.getX() . |
boolean |
isAdditionalSpaceRequiredY()
Return true if this point painter needs more space in y dimension than
TracePoint2D.getY() . |
boolean |
isPixelTransformationNeededX()
Return true if rendering in x dimension requires a transformation from
pixel to value domain.
|
boolean |
isPixelTransformationNeededY()
Return true if rendering in y dimension requires a transformation from
pixel to value domain.
|
void |
paintPoint(int absoluteX,
int absoluteY,
int nextX,
int nextY,
Graphics g,
ITracePoint2D original)
Paint the point given by absolute coordinates on the given graphic context.
