Enclosing class:

GuiUtils.JTables

public static class GuiUtils.JTables.VisitingZoom
extends Object

Stateful "visiting zoom" helper used by table panels that navigate the canvas on double-click (BookmarkManager, CurationManager, SeedOverlayPanel). Holds the percentage, exposes it as a fraction (for ImpUtils.zoomTo(...)), and produces a bound JSpinner. The default is roughly two zoom steps above the current canvas magnification, falling back to 600% when no image is loaded.

Constructor Details

VisitingZoom

public VisitingZoom()

VisitingZoom

public VisitingZoom(int initialPercentage)

Method Details

percentage

public int percentage()

Returns:

current zoom level in percent (in [25, 3200]).

fraction

public double fraction()

Returns:

current zoom level as a fraction (e.g. 6.0 for 600%).

setPercentage

public void setPercentage(int p)

Sets the percentage, clamped to the allowed range.

resetFor

public void resetFor(ij.ImagePlus imp)

Resets the percentage to roughly two zoom steps above the image canvas's current magnification, or 600% when imp == null or has no canvas yet.

buildSpinner

public JSpinner buildSpinner()

Builds a JSpinner bound to this state. Editing the spinner updates the percentage; external mutations need to call setValue on the spinner directly.

defaultPercentageFor

public int defaultPercentageFor(ij.ImagePlus imp)
