Using Image Scaling
The Image Scaling function performs two tasks. It
compares two or more images to each other using their relative sizes.
It can
also show the actual size of an image in reference to the dimensions in
the Viewable Screen Area, which
are defined by width and height in the Measurement and Scaling tool.
Relative Size
Bring two or more images into the Image Workspace.
Define the width and
height for each image. Follow
the instructions for defining width and height located in Measurements
and Scaling. Once
all the height and width for all the images are defined, click on the
Relative Size button on the Measurement
and Scaling tool. The
images in the Image Workspace will now change sizes relative to each other.
You may
need to open an image using the Select
and Move Image function on the Image Workspace Tool to compare
the relative size of the images.
For example, if you have one image that
has the height of 10 inches and a width of 5 inches, and you compare the
relative size of that image to an image with a height of 20 inches and
a width of 10 inches, your result would be that the larger image would
be twice the size of the smaller image in the Image Workspace. Image
Scaling is very useful to get a feel for the real size of the images you
are viewing in the Image Workspace.
Actual Size
The actual size function changes the image and
viewable screen area size in reference to the actual size of the active
image against the dimensions defined in the Viewable
Screen Area: as width and height in inches.
For example, if you have an image that has a width
of 5 inches and a height of 10 inches in Image
Dimensions; and in the Image
Scaling function , you
have 5 inches for the width and 10 inches for the height, and you clicked
on Actual Size, the image will
open to be the same size as the screen area because the height and width
of the image and the screen are the same. (You
may need to use the Select and Move function on the toolbar to see the
entire image.) If
you leave the height and width of the image as it is above, and then change
the Viewable Screen Area to a
width of 10 and a height of 20 inches, for example, and then click Actual Size, now the screen will be
twice as large as the image.
