Using Selections
A selection marks off areas of the
canvas for “special treatment.” It can
either protect an area from change or
designate the area that you want to
change.
You can save selections as alpha
channels. This lets you store selections
and edit them with brushes and image
effects. For more information about
alpha channels, refer to
“Understanding Alpha Channels” on
page 219.
Having one selection, but multiple
channels, is convenient and powerful.
It’s easy to save selections, then
reactivate them later. You can also
create a selection from multiple
channels by adding, subtracting, or
intersecting them.
Working with Selections
Corel Painter provides a variety of
tools and commands for creating
selections in a document. Each time
you create a new selection, Corel
Painter deactivates the old one.
You can use selections in several ways:
• To constrain brush strokes. You
can protect the area inside or
outside the selection.
• To isolate an area of the canvas for
applying an image effect. Corel
Painter applies the effect only to
the selection. You can also set
different levels of protection within
a selection to create partial
intensity of the effect.
• To choose the area of the canvas
you want to cut or copy.
• To choose the area of the canvas
that you want to move or copy to a
new layer.
