Package sc.fiji.snt.viewer

Class Bvv.AnnotationOverlay

java.lang.Object

sc.fiji.snt.viewer.Bvv.AnnotationOverlay

All Implemented Interfaces:

AbstractBigViewer.AnnotationOverlay

Enclosing class:

Bvv

public static class Bvv.AnnotationOverlay
extends Object
implements AbstractBigViewer.AnnotationOverlay

Renders spherical annotations at SNTPoint world coordinates. Rendered with CPU (Java2D) but optimized with caching and batched rendering.

Method Summary

Modifier and Type	Method	Description
void	addAnnotation(SNTPoint p, float radius, Color color)	Add a single annotation.
void	addAnnotations(Collection<SNTPoint> points, float radius, Color color)	Add annotations to the current list.
void	clear()	Remove all annotations.
int	getCount()	Returns the number of annotations currently in the overlay.
int	hitTest(int screenX, int screenY)	Hit-tests the last-rendered screen circles against (screenX, screenY).
boolean	isVisible()	Returns true if the overlay is currently rendered.
void	replaceAll(List<SNTPoint> points, List<Float> sizes, List<Color> colors)	Replaces all annotations in one shot with a single repaint.
void	setAnnotations(Collection<SNTPoint> points, float radius, Color color)	Replace the current annotations with the provided list.
void	setSelectedIndex(int index)	Highlights the annotation at the given model index by rendering it in a contrasting color.
void	setVisible(boolean visible)	Show/hide annotations
void	updateScene()	Ensure renderers/nodes reflect current annotation list.

Method Details

setAnnotations

public void setAnnotations(Collection<SNTPoint> points,
 float radius,
 Color color)

Replace the current annotations with the provided list.

addAnnotations

public void addAnnotations(Collection<SNTPoint> points,
 float radius,
 Color color)

Add annotations to the current list.

addAnnotation

public void addAnnotation(SNTPoint p,
 float radius,
 Color color)

Add a single annotation.

Specified by:

addAnnotation in interface AbstractBigViewer.AnnotationOverlay

Parameters:

p - the position (world coordinates)

radius - sphere radius in physical units

color - fill color

clear

public void clear()

Remove all annotations.

Specified by:

clear in interface AbstractBigViewer.AnnotationOverlay

isVisible

public boolean isVisible()

Description copied from interface: AbstractBigViewer.AnnotationOverlay

Returns true if the overlay is currently rendered.

Specified by:

isVisible in interface AbstractBigViewer.AnnotationOverlay

getCount

public int getCount()

Returns the number of annotations currently in the overlay.

Specified by:

getCount in interface AbstractBigViewer.AnnotationOverlay

setVisible

public void setVisible(boolean visible)

Show/hide annotations

Specified by:

setVisible in interface AbstractBigViewer.AnnotationOverlay

Parameters:

visible - true to show, false to hide

updateScene

public void updateScene()

Ensure renderers/nodes reflect current annotation list.

Specified by:

updateScene in interface AbstractBigViewer.AnnotationOverlay

setSelectedIndex

public void setSelectedIndex(int index)

Description copied from interface: AbstractBigViewer.AnnotationOverlay

Highlights the annotation at the given model index by rendering it in a contrasting color. Pass -1 to clear any existing highlight.

Specified by:

setSelectedIndex in interface AbstractBigViewer.AnnotationOverlay

Parameters:

index - model index of the annotation to highlight, or -1 for none

hitTest

public int hitTest(int screenX,
 int screenY)

Hit-tests the last-rendered screen circles against (screenX, screenY). Uses a minimum hit radius of 4 px so tiny markers remain clickable.

Specified by:

hitTest in interface AbstractBigViewer.AnnotationOverlay

Parameters:

screenX - x coordinate in viewer-display pixels

screenY - y coordinate in viewer-display pixels

replaceAll

public void replaceAll(List<SNTPoint> points,
 List<Float> sizes,
 List<Color> colors)

Replaces all annotations in one shot with a single repaint. Overrides the default to avoid the per-call repaints from clear() and addAnnotation(), which can produce visible flicker.

Specified by:

replaceAll in interface AbstractBigViewer.AnnotationOverlay

Parameters:

points - list of positions (world coordinates); null entries are skipped

sizes - sphere radii in physical units, parallel to points

colors - fill colors, parallel to points; null entries use Color.YELLOW
