With Image Composer, each image is an independent image with shape. These images are called sprites .
Sprites are easy to arrange, group, move, size, and transform with effects.
When you work with sprites, you don't have to learn about layers, channels, or masks in order to get professional-looking results. Each sprite in Image Composer has built-in transparency information which means that the area around a sprite can be transparent, resulting in a nonrectangular image with shape. The following sprites were arranged together in Image Composer in a few simple steps. This effect demonstrates how a sprite can have varying levels of transparency within its shape as well as around its shape. To complete this task in other image editing applications would require that you learn about and then use masks, channels, and layers.
