Manipulating Images 47

• Select a preferred scale (either "Pixels" or "Percent") in the drop-

down list.

• Select a resampling method. As a rule, use Nearest Pixel for hard-

edge images, Bilinear Interpolation when shrinking photos,

Bicubic Interpolation when enlarging photos, and Lanczos3

Window when best quality results are expected.

5. If adjusting printed dimensions, select your preferred units of

measurement and resolution. The pixel size will automatically alter

with print size adjustment.

6. Enter the new values and click OK.

Changing canvas size

PhotoPlus provides several ways of changing the canvas size that was originally

chosen when creating a new image (see p. 18). If you just want to reduce the

canvas area, you can use the Crop Tool (see Cropping an image on p. 48) or the

Image>Crop to Selection command. To either enlarge or reduce the canvas, the

Image>Canvas Size... command provides a dialog that lets you specify where

pixels should be added or subtracted.

To change canvas size:

1. Choose Canvas Size... from the Image menu.

2. Enter New Width and/or New Height values (the current values are

also shown for comparison). Alternatively, select the Relative check

box to enter the number of units you want to add or subtract from the

existing width and height values—for example, 5 pixels, 1 cm, 100

points, 10 percent, and so on.

3. In the Anchor box, click to position the image

thumbnail with respect to edges where pixels

should be added or subtracted. For example, if you

want to extend the canvas from all sides of the

image, click the center anchor point.

4. Click OK.
