Cropping an image
The Image Editor’s cropping function allows you to conserve a selected portion of the image,
while removing the remaining portions surrounding the selected area (see figure
5-8 ).
Cropping is a popular image processing technique that is commonly used to focus the image
on a particular subject or area on the image.

Since cropping permanently alters the image, the Image Editor allows you to save a copy
of the changed image before the cropping is actually performed. As a result you can
preserve the original state of the image asset.
A bounding outline surrounds the image when it is opened in the Image Editor (figure 5-8 ). The
bounding outline is a frame that is used for defining the area of interest when using the
cropping feature. In other words, the content inside of the bounding outline will be preserved,
while whatever is outside the bounding outline will be permanently removed. When the Image
Editor is in crop mode, dragging the bounding outline’s corner handles (squares) allow you use
to resize the bounding outline around the area of interest on the image. If the “U
SE AREA OF
INTEREST ASPECT RATIO ” check box is selected, then the bounding outline can only be resized
to dimensions that maintain the aspect ratio of the image’s placeholder on the scene, template,
or control panel. Clearing this check box allows you to resize the bounding outline freely
without any aspect ratio restrictions.
When resizing or repositioning the bounding outline, its dimensions and location is display
in the lower right corner of the Image Editor window (figure
5-9 ). The first set of number
displays the X/Y dimensions of the bounding outline in pixels, while the second set
represents the location coordinates of the bounding outline’s upper left corner.
