  1. 470 LESSON 17 Creating Animated Images for the Web 3 In the Animation palette, click the New Frame button ( ) to create a second frame. In the Layers palette, click to turn off the link icon ( ) between the layer and clipping path thumbnails. Turning off the link icon lets you move the layer independent of its layer mask. 4 Select the move tool ( ). 5 In the Layers palette, click the layer thumbnail for the juice layer to select the layer. 6 In the image, position the move tool over the orange color, and drag to reposition the orange color beneath the curve of the “U.” 7 In the Animation palette, drag to reverse the order of frames 1 and 2.
  2. ADOBE PHOTOSHOP 6.0 471 Classroom in a Book Because you have defined the two frames by repositioning a single layer, you can generate intermediate frames automatically using the Tween command. 8 Choose Tween from the Animation palette menu. Select All Layers and Position; deselect Opacity and Effects; for Tween With, choose Next Frame; and enter 5 in the Frames to Add text box. Click OK. 9 In the Animation palette, select frame 1; in the Layers palette, select the Photo layer and show it. From the Animation palette menu, choose Match Layer Across Frames to reveal the photo in all frames. 10 In the Animation palette, select frame 1. Then click the Play button ( ) to play the animation. Click the Stop button ( ) to stop the animation. 11 Choose File > Preview In, and choose a browser application from the submenu to play the animation with accurate timing. You can also select Preview in Default Browser in the toolbox. 12 Choose File > Save Optimized As, name the file Logo3.gif, and click Save. Then choose File > Close to close the original file without saving changes. Using clipping groups to create animations Now you’ll create the effect of strawberries shaking inside the logo text. 1 Choose File > Open, and open the file Logo4.psd from the Lessons/Lesson17 folder. 2 In the Layers palette, make sure that both the Strawberries and Text layers are visible. To make the strawberries appear only through the shape of the logo text, you’ll create a clipping group.
  3. 472 LESSON 17 Creating Animated Images for the Web 3 In the Layers palette, select the Strawberries layer. Hold down Alt (Windows) or Option (Mac OS), position the pointer over the solid line dividing two layers in the Layers palette (the pointer changes to two overlapping circles), and click the dividing line between the layers. You can also choose Layer > Group with Previous. Notice that the strawberries now appear masked by the logo text. The thumbnail for the Strawberries layer is indented with a downward-pointing arrow ( ), indicating that the layer is grouped with the layer that precedes it. 4 In the Animation palette, click the New Frame button. For the second animation frame, you’ll reposition the Strawberries layer slightly. 5 In the Layers palette, select the Strawberries layer. Then select the move tool ( ). 6 In the image, drag the Strawberries layer slightly to the right, or use the arrow keys to move the layer.
  4. ADOBE PHOTOSHOP 6.0 473 Classroom in a Book 7 Click the Play button ( ) to play the animation. The strawberries shake from side to side inside the logo text. 8 Click the Stop button ( ) to stop the animation. 9 Choose File > Preview In, and choose a browser application from the submenu to play the animation with accurate timing. 10 Choose File > Save Optimized As, name the file Logo4.gif, and click Save. ImageReady saves the animation as a GIF using the current settings in the Optimize palette. 11 Choose File > Close to close the original file without saving changes.
  5. 474 LESSON 17 Creating Animated Images for the Web Review questions 1 Describe a simple way to create animation. 2 In what instances can you tween animation frames? When can’t you tween frames? 3 How do you optimize an animation? 4 What does optimizing an animation accomplish? 5 What is frame disposal? Which frame disposal method should you generally use? 6 How do you edit an existing animation frame? 7 What file formats can you use for animations? Review answers 1 A simple way to create animation is to start with a layered Photoshop file. Use the New Frame button in the Animation palette to create a new frame, and use the Layers palette to alter the position, opacity, or effects of one of the selected frames. Then create interme- diate frames between the selection and the new frame either manually using the New Frame button or automatically using the Tween command. 2 You can instruct Adobe ImageReady to tween intermediate frames between any two frames, to change layer opacity or position between two frames, or to add new layers to a sequence of frames. You cannot tween discontiguous frames. 3 Click the Show Options button in the Optimize palette, and then choose File > Save Optimized to optimize animations. Choose Optimize Animation from the Animation palette menu to perform optimization tasks specific to animation files, including removing redundant pixels and cropping frames according to the bounding box. 4 In addition to the optimization tasks applied to standard GIF files, ImageReady generates an adaptive, perceptual, or selective palette for the file based on all frames in the animation if you selected one of those palettes. ImageReady applies a special dithering technique to ensure that dither patterns are consistent across all frames, to prevent flickering during playback. The application also optimizes frames so that only areas that change from frame to frame are included, greatly reducing the file size of the animated GIF.
  6. ADOBE PHOTOSHOP 6.0 475 Classroom in a Book 5 A frame disposal method specifies whether to discard the selected frame before displaying the next frame when an animation includes background transparency. This option determines whether the selected frame will appear through the transparent areas of the next frame. Generally, the Automatic option is suitable for most animations. This option selects a disposal method based on the presence or absence of transparency in the next frame, and discards the selected frame if the next frame contains layer transparency. 6 To edit an existing animation frame, you first select the frame, either by clicking the frame thumbnail in the Animation palette or by navigating to the desired frame using the First Frame, Backward, or Forward buttons in the Animation palette or Layers palette. Then edit the layers in the image to update the contents of the selected frame. 7 Files for animations must be saved in GIF format or as a QuickTime movie. You cannot create animations as JPEG or PNG files.
