When you resize a picture block, it retains its rectangular shape. But you can change a picture block to one of 15 other geometric shapes, including circular, triangular, and rhombic shapes.

1. Select the picture block whose shape you want to change, and choose Specifications from the Document menu. Or double-click the object. The Picture Block Specifications dialog box appears.

2. Press the icon of the current shape, and then choose the shape you want.

3. Click OK.
