Use the Rounded Rectangle Tool to create rectangles and squares with rounded corners. To draw a rounded rectangle, position the mouse cursor over your picture where you want the top left corner of the rectangle to begin. Hold down the left mouse button and drag the cursor to where you would like the opposite corner. When your rectangle reaches the desired size and shape, release the mouse button.
When the Rounded Rectangle Tool is active, the Option Panel includes a control to set the angle used for the corners.
The Option Panel's Corner slider allows you to specify the angle to use for the corners of the rounded rectangle.
You can enable the Anti-alias option to smooth the corners of the rectangle.
To create a rounded rectangle without a border, set the Line Width slider on the Option Panel to zero. A hollow rounded rectangle can be created by selecting the Hollow/No Fill button from the Fill Selector.
