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).
The Magnify Tool can be called in the following
order, from the image-menu:
The Tool can also be called by clicking the tool icon:

The available tool options for Magnify can be accessed by double
clicking the Magnify tool icon.
Allow Window Resizing
This option will allow the window containing your image to be
resized if the zoom level dictates it.
The two available tool toggles are used for changing the zoom
direction between zooming in and zooming out.
This option sets the size that a dragged zoom rectangle
must be before zooming to that rectangle actually occurs. A higher
Threshold will require a larger rectangle before zooming to that
rectangle happens. With a low level, a very small rectangle will
push you towards a more than 2000% zoom level.
Using the Magnify 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.
