Creates a select area in a raster image by drawing a polygon around pixels that you define.
A select area is a user-defined area of individual pixels or groups of pixels within an image. You can create a select area for editing purposes.
Following the first point, click the points to define the polygon. Points are placed when you release the mouse button. To remove a point or back up, press the Backspace key. Right-click to end the polygon. The solid select area outline then becomes a dotted outline.
As you create a select area with the Polygonal Select Area command, you can use the following modifier keys to change the behavior of your selection:
Keyboard Modifier |
Result |
Alt |
Adds a new area to an existing select area (union). |
Space Bar |
Subtracts the overlapping area from the existing select area (difference). |
Space Bar + Alt |
Designates the overlapping area as the new select area (intersection). |
The Shift key is not a valid modifier for the Polygonal Select Area command.
To use this functionality, you must install the Image Integrator option.
