loads. It entertains viewers while reassuring them that something is happening, and in many cases, lets them know how much of the file has loaded. 2 The bitmap caching feature enables you to play back complex animated vector graphics without sacrificing the quality of the movie's performance. You can specify that an object be cached as a bitmap at the time the movie is run, preventing Flash from having to continually redraw the symbol. 3 To make an instance invisible, use ActionScript to set the visible property of the instance to false.   11. Publishing Flash Documents [View full size image] When you've finished your animation, publish it as a SWF file for a website or a DVD, or save frames from the animation as image files. Lesson Overview In this lesson, you'll learn how to do the following: * Test a Flash document * Change publish settings for a document * Understand the difference between image file types * Add metadata * Publish a SWF file * Detect the version of Flash Player a viewer has installed * Publish a self-contained projector file This lesson will take less than an hour to complete. If needed, remove the previous lesson folder from your hard drive, and copy the Lesson11 folder onto it. Getting Started In this lesson, you'll publish the animation that you created in Lesson 5. You'll publish the movie for a website, capture specific frames as images, and save the movie so that it will play even when Flash Player isn't present. 1. Double-click the 11Start.fla file in the Lesson11/11Start folder to open it in Flash. 2. Choose File > Save As. Name the file 11_workingcopy.fla, and save it in the 11Start folder. Saving a working copy ensures that the original start file will be available if you wish to start over.   Testing a Flash Document Troubleshooting is a skill you develop over time, but it's easier to identify the cause of problems if you test your movie frequently as you create content. If you test after each step, you know which changes you made and, therefore, what might have gone wrong. A good motto to remember is "Test early. Test often." One fast way to preview a movie is to choose Control > Test Movie, as you've done in earlier lessons. This command creates a SWF file so that you can play the movie; it does not create the HTML file or any other files necessary to play the movie from a website or DVD. When you believe you've completed your movie, or a portion of the movie, take the time to make sure all the pieces are in place and that they perform the way you expect them to. 1. Review the storyboard for the project, if you have one, or other documents that describe the purpose and requirements of the project. If such documents do not
