Offsetting selections You can shift an image area with the Offset filter. Canvas fills the vacated area with color, duplicated pixels, or parts of the offset area. To offset image areas 1 With an image in edit mode, select an image area. 2 Choose Image > Filter > Other > Offset. 3 Enter horizontal and vertical offset amounts in pixels. Positive values result in offsets to the right and down; use negative numbers (preceded by a minus sign) to offset up and left. 4 Choose an option under Undefined Areas. 5 To see the effect of the settings, turn on Preview. When the set- tings are correct, click OK. Ripple effects With the Ripple filter you can create the impression of ripples in an image, like the ripples made by dropping a stone into smooth water. By varying the controls in the Ripple dialog box, you can produce a range of effects in an image, from slight rippling to extreme distor- tion.
