View Tools View Tools

There are two tools used to change the current view; Zoom and Pan. These tools alter the way the image is presented, they do not change the image itself.

Zoom Zoom

The Zoom Tool is used to magnify (or enlarge) the view, or to reduce (or shrink) the view.

Use the Left Mouse button to zoom in on the canvas. The Right Mouse button zooms out.  The individual zoom levels are predefined and are not customizable.


The Mouse Wheel used in conjunction with the Ctrl key duplicates the action of the Zoom Tool.

When the Zoom Tool is active, clicking and dragging a rectangle will maximize the specified area in the Editing Window.

Pan Pan

The Pan Tool allows the user to scroll or pan an image.  This is particularly useful when navigating an image larger than the Editing Window (when zoomed in).

Click and drag the canvas to move it around within the Editing Window.


The functionality of the Pan Tool is available when any other tool is active.  Hold down the Space bar and click and drag to pan the image.


Scroll the image vertically at any time using the Mouse Wheel.  Hold down the Shift key to swap the direction of scrolling to horizontal.

Note that it is not possible to scroll past the edge of the canvas.  Once the edge of the canvas meets the limit of the Editing Window scrolling and panning stops.
