• Circle: Particles emerge from a circle-shaped emitter. Particles can be emitted in an
Outline, Tile Fill, or Random Fill pattern. This emitter shape is good for surrounding an
element in a composition with particles that emerge from its edge. Using the onscreen
controls (with the Adjust Item tool), you can specify the size and location of the circle.
Depending on the selected Arrangement, the Circle emitter shape displays additional
parameters. In the following image, the shape’s Arrangement parameter is set to Outline.
• Burst: Particles emerge from a burst pattern. Using the onscreen controls (with the
Adjust Item tool), you can specify the size and location of the burst. The Burst shape
displays additional parameters.
