The Crop Tool is used to crop or clip an image or layer. This tool
is often used to remove borders, or to eliminate unwanted areas to
provide you with a more focused working area. It is also useful
if you need a specific image size that does not match the original
dimensions of your image.
To use the tool, click inside the image and drag out a rectangular
region before releasing the mouse button. When you click, a dialog
pops up showing you the dimensions of the crop region, and allowing
you to perform various actions. If you want to alter the crop
you can do so either by clicking and dragging on the corners, or by
changing the values in the dialog. When you are ready, you can
complete the operation either by clicking inside the crop region,
or by pressing the Crop or Resize buttons on the dialog. (See
below for what these mean.)
If you find that the dialog gets in your way more than it helps
you, you can prevent it from appearing by holding down the
Shift key when you first click on the image.
Working this way means altering the crop region by dragging the
corners, and executing the operation by clicking inside the

Crop Mode is the standard mode of operation for the Crop Tool.
Cropping an image or layer will change a layer by eliminating
everything outside the cropping area. The cropping area can be set
by either dragging the tool to form a rectangle area or manually
setting the origin, width, and height. Cropping areas can also be
set based on an existing selection or by using the Auto Shrink
button. These options are available within the Crop And Resize
Information dialog which is shown when the Crop Tool is clicked on
an image or layer.
If you are cropping an image (not just a layer), then Resize Mode
changes the shape of the image without altering the size or shape
of the layers it contains. This may leave parts of some layers
extending beyond the edges of the image, where you cannot see
them, but if you move the layers, you will see that the contents
still exist. If you are cropping a layer, Resize Mode does the
same thing as crop mode.
You can also switch to Resize mode in two other ways: first, by
using the Resize button on the dialog instead of the Crop
button; second, by holding down the Ctrl
key while you click inside the crop region to complete the

Fixed Aspect Ratio
With this option, cropping will respect a fixed ratio between
Width and Height.
Crop And Resize Information
The Origin selectors allow the manual setting of the top left
corner of the cropping region. The units may also be chosen.
The Width and Height selectors allow the manual setting of both
the width and the height of the cropping area. The units may
also be chosen.
This button will resize the cropping area to encompass all
active selections contained within the image. If there is no
selection, the cropping area is the whole image.
The Auto Shrink button will attempt to locate a border from
which to draw dimensions from. This option only works well
with isolated objects contrasting sharply with background.
Crop and Resize buttons
These two buttons act according to their function, ignoring the
mode setting in tool options.
