Selecting areas by painting

You can create a freehand selection by painting with the Selection Brush tool or any brush variant that uses the Selection method. Use Corel Painter’s interactive and dynamic brush shapes to quickly generate new, additive, or subtractive selections.

Examples of selections created with Selection brush variants using different dab types

You can choose a Selection brush from the preset selection brushes available in Corel Painter or create your own custom brush from any brush that uses the following dab types: Circular, Computed Circular, Captured, Single-Pixel, Static Bristle, Dynamic Speckle Bristle, and Dynamic Speckle Particle types (Flow, Gravity, and Spring). Selection brushes support grain and opacity, and work with all other selection tools.

You can customize Selection brushes by using brush controls. For more information, see Adjusting brushes with brush controls.

As you brush over an image to make a selection, a color overlay appears, to help you distinguish selected areas from protected areas. By default, the overlay is a red-tinted, transparent sheet. However, if your underlying brushstrokes are red, you can change the overlay color so that the overlay can be seen clearly against the image colors. You can adjust the overlay opacity, and you can also choose to display the overlay over selected or protected areas.

By default, the overlay is no longer visible after you complete a selection. Instead, a dashed outline — marquee — appears around the selection to indicate the border separating the selected area from the protected area. If you find it useful to have the color overlay visible at all times, you can easily display it.

The overlay that appears as you paint (top) and the marquee that appears when you complete the selection (bottom) help you distinguish protected areas from editable areas.

When painting with a Selection brush, you can automatically align brushstrokes to a curve. For more information about aligning brushstrokes to paths and shapes, see Aligning brushstrokes to paths and shapes.

When painting with a Selection brush, you can align brushstrokes to perspective guides. For more information about perspective guides, see Using Perspective Guides.
