Corel Painter Help | Getting started with selections

Getting started with selections

You can use selections to isolate an area of the canvas to apply effects or transformations, while protecting the unselected areas from the changes.

Selection types

Corel Painter supports two types of selections: path-based and pixel-based. The method that you use to create a selection determines its type.

• Path-based selections are defined by a closed path, for example a circle or a square. You can make path-based selections by using the Rectangular Selection, Oval Selection, Lasso tool, or by converting a shape. Path-based selections support many transformations that pixel-based selections do not. In addition, it’s the only type of selection that you can store in the Selection Portfolio.

• Pixel-based selections are defined at the pixel level. You can create a pixel-based selection by using the Magic Wand tool. Corel Painter also includes options for auto-generating selections based on various image or clone characteristics.

You can covert a pixel-based selection to a path-based selection. For more information, see To convert a pixel-based selection to a path-based selection.

Selection methods

The following table describes the various methods for using selections.

Selection storage

In Corel Painter, each new selection automatically replaces the current selection, therefore, you need to store a selection in order to reuse it. Corel Painter includes two options for storing the selections that you want to reuse.

Option	Description
Alpha channels	Stores both path-based and pixel-based selections for the current document. You can modify alpha channels by combining them with the current selection.
Selection Portfolio	Stores path-based selections in a library to make them accessible from any document
