6.3. Zoom

Figure 13.162. The “Zoom” tool in Toolbox

The Zoom tool in Toolbox

The Zoom Tool is used to change the zoom level of your working image. If you only click on the image, the zoom is applied to the whole image. But you can also click-and-drag the mouse pointer to create a zoom rectangle. Then, the action of this rectangle is better understood if the “Allow window resizing” option is unchecked: you can see that the content of this rectangle will be enlarged or reduced so that its biggest dimension fit the corresponding dimension of the image window (if the biggest dimension of the rectangle is width, then it will fit the width of the image window).

6.3.1. Activating the Tool

  • You can get to the Zoom Tool from the image-menu through : ToolsZoom,

  • or by clicking the tool icon: in Toolbox.

6.3.2. Key modifiers (Defaults)


Holding Ctrl when clicking on a point of your image will change the zoom direction from zooming in to zooming out.

Ctrl+Mouse wheel

Spinning the mouse wheel, while pressing Ctrl, varies the zoom level.

6.3.3. Options

Auto-resize window

This option will allow the canvas to be resized if the zoom level dictates it.

Tool Toggle

The two available tool toggles are used for changing the zoom direction between zooming in and zooming out.

6.3.4. Zoom menu

Using the Zoom tool is not the only way to zoom an image. The Zoom menu provides access to several functions for changing the image magnification level. For example, you can easily choose an exact magnification level from this menu.
