Purpose

The module SoView2DSliceZoom allows for a zooming in and out of a 2D viewer slice interactively.

Usage

Press the mouse button and the modifier key as you set on the module’s GUI and move the mouse up and down to zoom in and out.

If the module zooms in on moving the mouse up or down depends on the Drag Mode.

Move the mouse anywhere over the viewer and press return to zoom. The module not only zooms on pressing return but also shifts into the direction of the mouse cursor, seen from the middle of the viewer.

Visible Fields

Editing On

name: editingOn, type: Bool, default: TRUE

Alt

name: alt, type: Enum, default: IGNORED

Set handled-flag

name: setEventHandled, type: Bool, default: TRUE, deprecated name: setHandled

see SoView2DExtension.setEventHandled

Evaluate handled-flag

name: ignoreHandledEvents, type: Bool, default: FALSE, deprecated name: evalHandled

see SoView2DExtension.ignoreHandledEvents

Min

name: min, type: Float, default: 1

Sets the minimum zoom level.

Max

name: max, type: Float, default: 100

Sets the maximum zoom level.

Sensitivity

name: sensitivity, type: Float, default: 100, minimum: -1000, maximum: 1000

Sets the sensitivity of the zooming. A higher sensitivity leads to a faster zooming.

Negative values lead to zooming in the opposite direction.

Drag Mode

name: dragMode, type: Enum, default: DRAG_TAKE_AND_PUSH

Defines the drag mode.

Values:

Title	Name
​Take And Push	​DRAG_TAKE_AND_PUSH
​Approach And Depart	​DRAG_APPROACH_AND_DEPART

Evaluate started-flag

name: evalStarted, type: Bool, default: FALSE

If checked, the module reacts only if an interaction (shifting) is started in the target viewer.

Use Alternative Zoom Formula

name: useAlternativeZoomFormula, type: Bool, default: TRUE

If checked, the module zooms in a linear manner. Otherwise, the zooming is getting slower the more you zoom in.

Zoom Around Click Position

name: zoomAroundClickPosition, type: Bool, default: FALSE

If checked, the module zooms around the click position. Otherwise, the module zooms around the zoom center specified in the attached SoView2D module.
