Refine selections
After making a selection, you can use options in the Select and Mask tool to enhance it by adding or removing areas from an existing selection, adjusting its softness, roundness, size, or using the Smart Refine tool. After refining a selection, you can also choose what to do with it — add a mask created from the selection to the same or a duplicate layer, create a new layer with selection contents, or just keep it as a selection.
Manually refine a selection
- Make a selection.
Do one of the following:
- With one of the selection tools active, click the Select and Mask button in the Tool Options pane.
- Choose Edit > Select and Mask (from the Edit menu at the top of your screen).
- Choose Tools > Select > Select and Mask (from the Tools menu at the top of your screen).
- Press + + on your keyboard.
Note: While the Select and Mask is active, your selection outline is replaced by an overlay. Any selected areas are see-through, while any unselected areas are colored in. Pixelmator Pro uses a yellow by default but you can choose red, black, white, or plain black & white overlay from the Overlay pop-up menu.
Adjust the options in the Tool Options pane:
- Shape Roundness: Adjust how much to round the selection outline.
- Edge Softness: Adjust how much to soften the edges of the selection outline. With softer edges, the selected area will blend in better with other parts of the image should you copy or edit it.
- Expand: Change the size of the selection.
In the Output pop-up menu, select what you'd like to do with your refined selection:
- Selection: Applies the refined selection to a layer.
- Mask: Applies a mask created from the refined selection to the active layer.
- New Layer with Mask: Creates a duplicate of the active layer and applies a mask created from the refined selection.
- New Layer: Creates a new layer with the contents of the refined selection. Pixelmator Pro will automatically decontaminate the edges of the selection, removing any color left from the previous background.
Click Apply at the bottom of the Tool Options pane to apply your refinements to the selection.
Automatically refine a selection using Smart Refine
Smart Refine uses a machine learning-based algorithm to intelligently detect intricate details like hair or fur at the selection edges and automatically refine the selection outline for you. To use Smart Refine:
- Make a selection.
- Do one of the following:
- Choose Edit > Smart Refine (from the Edit menu at the top of your screen).
- Choose Edit > Select and Mask and click Smart Refine in the Tool Options pane.
- Press + + on your keyboard.
- Click Apply at the bottom of the Tool Options pane to apply your refinements to the selection.
Add or subtract areas from an existing selection
While the Select and Mask tool is active, you can use the selection refinement brush to paint over areas in your image to quickly edit your selection.
- Choose a brush type you want to use:
- Refine Edge Brush: Adds or subtracts only at the edges of the selection.
- Quick Selection Brush: Adds or subtracts from selection as if using the Quick Selection tool.
- Basic Brush: Adds or subtracts from selection as if painting with a basic brush.
- Choose the selection mode:
- If the Add selection mode is active, any areas you paint over will be added to your selection (and lose the color overlay).
- If you choose the Subtract selection mode, the areas you paint over will be removed from your selection (and will be covered by the color overlay).
- Adjust the size and softness of the brush.
- Paint over image areas you want to add or subtract from your selection.
