Making a selection

In any photo editing program, the

selection

tools and techniques

are as significant as any of

the basic brush tools or commands. The basic

principle is simple: quite often you'll want to

perform an operation on just a portion of the

image. To do this you must define an active

selection area.

The wide range of selection options in PhotoPlus lets you:

Define just about any selection shape, using various drawing and painting

techniques.

Modify the extent or properties of the selection (see p. 96)

Carry out various manipulations on the selected pixels, including cut, copy,

paste, rotate, adjust colors, apply special effects, etc. (see p. 100)

Selection basics

Although the techniques for using the various selection methods differ, the end

result is always the same: a portion of the active layer has been "roped off" from

the rest of the image. The boundary is visible as a broken line or marquee

around the selected region (see above).

Whenever there's a selection, certain tools and commands operate only on the

pixels inside the selection—as opposed to a condition where nothing is selected,

in which case those functions generally affect the entire active layer.

You may occasionally (especially if the marquee is hidden) find yourself

using a tool or command that seems to have no effect... it's probably

because there's still a selection somewhere, and you're trying to work

outside the selection. In this case, just cancel the selection.
