public interface IPointPainter<T extends IPointPainter<T>> extends java.io.Serializable, java.lang.Comparable<T>
Generic interface for instances that have to render a point in pixel coordinates.This low level interface is used wherever points have to be painted:
- painting traces (
ITracePainter
) - painting endpoints, startpoints and the segments of errorbars (
ErrorBarPainter
). - painting additional point highlighters (
ITracePoint2D.addAdditionalPointPainter(IPointPainter)
).

Method Detail
-
endPaintIteration
void endPaintIteration(java.awt.Graphics g2d)
Invoked to inform implementations that a paint iteration ends for the correspondingITrace2D
.- Parameters:
g2d
- provided in case pending paint operations have to be performed.
-
paintPoint
void paintPoint(int absoluteX, int absoluteY, int nextX, int nextY, java.awt.Graphics g, ITracePoint2D original)
Paint the point given by absolute coordinates on the given graphic context.The next coordinates are also provided to allow to check how much distance is available for the graphic representation of the current point.
- Parameters:
absoluteX
- the ready to use x value for the point to paint.absoluteY
- the ready to use y value for the point to paint.nextX
- the ready to use next x value for the point to paint.nextY
- the ready to use next y value for the point to paint.g
- the graphic context to paint on.original
- just for information, for painting this should be irrelevant and it should not be changed too!
-
startPaintIteration
void startPaintIteration(java.awt.Graphics g2d)
Invoked to inform implementations that a paint iteration starts for the correspondingITrace2D
.- Parameters:
g2d
- provided in case pending paint operations have to be performed.
