| Before the computer arrived on the scene and made life much easier for the animator, one of the major tasks for creating animation was to draw all the individual "in between" frames for an animation. This was usually done with a technique called onion skinning. Animators would start with a "working drawing" and place a thin sheet of paper, called an onion skin, over the top. They would draw the same image onto this onion skin paper using the working example underneath as a guide. By making subtle changes to the second and subsequent drawings, an animation was created. These days, we don't find this technique used as much because animation software creates these in between images for us. But, one of my readers recently needed to create the in betweens for one of her projects. Her first thought was to travel back in time several decades and draw each in between manually. Then a bright light bulb went off over her head and she realized she could still let FlashR do the work for her. She needed 10 in betweens. So she opened Flash, installed the beginning and ending object on the Flash Timeline and told Flash to create a 10-framed Tween. Now the task was to grab each frame of the tween as an image. Because these images were going to be used over a background image, she decided on a png format. Let's walk through the process in Flash CS5. Open a new ActionScript 3 project in Flash.
