1. Flash Macromedia Flash Introduction

2. Bitmap vs. Vector based • Bitmap • Bitmaps are made up of single pixels • Vector based • Vector graphics are made up of mathematical equations

3. Advantages of Vector-based Drawing Programs • Easy to resize without loss of quality • Small file size • Faster display and download

4. Animation • Graphics with added motion • Motion is illusion of motion • Single image is called a frame

5. Animation (cont.) • 24 frames per second are the threshold for the human eye to perceive single frames showing in sequence as continous motion

6. Frames • Frame • Single image displaying the object or character • Keyframe • Single Image where a significant change to the object or character is defined

7. Frames (cont.) • In-between Frames • Incorporate the incremental changes necessary to simulate movement • Tweening • Process of automatically creating in-between frames

8. Symbols • Symbols are reusable objects • Are stored in the library • Library is a container for reusable objects • Convert to symbol creates symbol and places it in Flash library

9. Symbol Instances • Instance of a symbol is usage of a symbol in your movie • Help to keep the file size small

10. Layers • Layers are like transparencies • Have a stacking order • Easy to make changes • Avoid unwanted object interaction

11. Usage of Layers • Layers avoid unwanted object interaction • Each object that you may want to animate should be placed on a separate layer • Rule of thumb: If in doubt, place the object on a separate layer
