12.6.3 Magnify Tool
Figure 12.81: Zoom tool
The Magnify 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).
