Constructor Detail

TransformedBoxOverlay

public TransformedBoxOverlay(net.imglib2.Interval interval)

TransformedBoxOverlay

public TransformedBoxOverlay(TransformedBox bbSource)

Method Detail

setPerspective

public void setPerspective(double perspective)

Sets the perspective value. perspective < 0 means parallel projection.

Parameters:

perspective - the perspective value.

showCornerHandles

public void showCornerHandles(boolean showCornerHandles)

fillIntersection

public void fillIntersection(boolean fillIntersection)

getFillIntersection

public boolean getFillIntersection()

setIntersectionFillColor

public void setIntersectionFillColor(Color intersectionFillColor)

drawOverlays

public void drawOverlays(Graphics g)

Description copied from interface: OverlayRenderer

Render overlays.

Specified by:

drawOverlays in interface OverlayRenderer

setCanvasSize

public void setCanvasSize(int width,
                          int height)

Description copied from interface: OverlayRenderer

This is called, when the screen size of the canvas (the component displaying the image and generating mouse events) changes. This can be used to determine scale of overlay or screen coordinates relative to the border.

Specified by:

setCanvasSize in interface OverlayRenderer

Parameters:

width - the new canvas width.

height - the new canvas height.

transformChanged

public void transformChanged(net.imglib2.realtransform.AffineTransform3D t)

Specified by:

transformChanged in interface TransformListener<net.imglib2.realtransform.AffineTransform3D>

boxDisplayMode

public org.scijava.listeners.ListenableVar<TransformedBoxOverlay.BoxDisplayMode,org.scijava.listeners.ChangeListener> boxDisplayMode()

Get/set BoxDisplayMode, which specifies whether to show 3D wireframe box (FULL), or only intersection with viewer plane (SECTION).

getBoxToViewerTransform

public void getBoxToViewerTransform(net.imglib2.realtransform.AffineTransform3D t)

Get the transformation from the local coordinate frame of the TransformedBox to viewer coordinates.

Parameters:

t - is set to the box-to-viewer transform.

getHighlightedCornerIndex

public int getHighlightedCornerIndex()

Get the index of the highlighted corner (if any).

Returns:

corner index or -1 if no corner is highlighted

getCornerHighlighter

public MouseMotionListener getCornerHighlighter()

Returns a MouseMotionListener that can be installed into a bdv (see ViewerPanel.getDisplay().addHandler(...)). If installed, it will notify a HighlightedCornerListener (see setHighlightedCornerListener(HighlightedCornerListener)) when the mouse is over a corner of the box (with some tolerance)/

Returns:

a MouseMotionListener implementing mouse-over for box corners

setHighlightedCornerListener

public void setHighlightedCornerListener(TransformedBoxOverlay.HighlightedCornerListener highlightedCornerListener)

setSourceSize

public void setSourceSize(double sourceSize)

Sets the source size (estimated maximum dimension) in global coordinates. Used for setting up perspective projection.

Parameters:

sourceSize - estimated source size in global coordinates
