The
submenu contains various commands which affect the magnification of the
image in the image window (zooming). Enlarging an image (zooming in) is
useful if you need to work with high precision, making pixel-level image
modifications or precise selections. On the other hand, reducing an image
(zooming out) is handy for getting an overall impression of the image and
seeing the results of changes which affect the entire image. Please note
that zooming is not undoable, since it does not affect the image data,
only the way it is displayed.

Besides the entries in this submenu, there is also a zoom pull-down menu
at the bottom edge of the image window (if the
status bar is
displayed), where several preset zoom levels are available.
You can also make settings regarding zooming in the
Navigation dialog. You
can also use the Magnify tool
which lets you zoom a particular area of the image.

5.4.1. Activate the Submenu
5.4.2. Contents of the “Zoom” submenu
The various “Zoom” submenu commands are described below,
along with their default keyboard shortcuts, if any.
-
Revert Zoom
-
(Shortcut: ` [grave
accent,“backtick”]) This command will reset the zoom
factor to the previous value, which is also shown by this label,
for example Revert Zoom (100%). If you never
changed the zoom factor of the active image, this entry is
insensitive and grayed out.
-
Zoom Out
-
(Shortcut: -) Each time “Zoom Out”
is used, the zoom factor is decreased by about 30%. There is a
minimum zoom level of 0.39%.
-
Zoom In
-
(Shortcut: +)
Each time “Zoom In” is used, the zoom factor is
increased by about 30%. The maximum possible zoom level is
25600%.

Note |
|
The keyboard shortcut for “Zoom In” has been
somewhat controversial because this is a very common operation
and on English keyboards, the Shift key must
be pressed to use it. (This is not the case for European
keyboards.) If you would like to have a different keyboard
shortcut, you can create a dynamic shortcut for it; see the
help section for User
Interface Preferences for instructions.

-
Fit Image in Window
-
(Shortcut:
Shift+Ctrl+E).
This command zooms the image to be as large as possible, while
still keeping it completely within the window. There will
usually be padding on two sides of the image, but not on all
four sides.
-
Fit Image to Window
-
This command zooms the image as large as possible without
requiring any padding to be shown. This means that the image
fits the window perfectly in one dimension, but usually
extends beyond the window borders in the other dimension.
-
A:B (X%)
-
With these commands, you can select one of the pre-set zoom
levels. Each of the menu labels gives a ratio, as well as a
percentage value. The 100% zoom level has a simple keyboard
shortcut: 1.
-
Other
-
This command brings up a dialog which allows you to choose any
zoom level you would like, within the range of 1:256 (0.39%) to
256:1 (25600%).

Tip |
|
When you are working at the pixel level, you can use the
New view command. This
allows you to see what is happening to the image at its normal size
at the same time.
