Manipulating Images 39

Modifying a selection

Once you've used a selection tool to select a region on the active layer, you can

carry out a number of additional steps to fine-tune the selection before you

actually apply an effect or manipulation to the selected pixels. Paint to Select

mode even lets you use standard painting or editing tools as selection tools!

Transforming the selection

The Selection Deform Tool on the

Tools toolbar's Deform Tools flyout lets

you transform, scale or rotate any already

drawn selection area. With the tool

enabled, square nodes on the mid-points

and corners of any selected area can be

dragged (opposite).

Look for the cursor changing between

resize and rotate modes when hovering

over a corner node.

Use in conjunction with the Ctrl key to transform the selection area without

constraint, creating a skewed transform (drag nodes as appropriate). The Alt

key resizes the area about its center, while the Shift key maintains the area’s

aspect ratio. It’s also possible to move the small center of rotation “handle” in

the center of the transform to produce an arc rotational movement rather than

rotating around the area’s center (by default).

Holding down the Shift key whilst rotating will cause a movement in

15 degree intervals.

Making the selection larger or smaller

If the selection you've made isn't quite the right shape, or doesn't quite include

all the necessary pixels (or perhaps includes a few too many), you can continue

to use the selection tools to add to, or subtract from, the selected region.
