FLASH CS3 36 User Guide 2 Select from the following options: • To change the width of frame cells, select Tiny, Small, Normal, Medium, or Large. (The Large frame-width setting is useful for viewing the details of sound waveforms.) • To decrease the height of frame cell rows, select Short. Short and Normal frame view options • To turn the tinting of frame sequences on or off, select Tinted Frames. • To display thumbnails of the content of each frame scaled to fit the Timeline frames, select Preview. This can cause the apparent content size to vary and requires extra screen space. • To display thumbnails of each full frame (including empty space), select Preview In Context. This is useful for viewing the way elements move in their frames over the course of the animation, but previews are generally smaller than with the Preview option. About layers Layers help you organize the artwork in your document. You can draw and edit objects on one layer without affecting objects on another layer. In areas of the Stage with nothing on a layer, you can see through it to the layers below. To draw, paint, or otherwise modify a layer or folder, select the layer in the Timeline to make it active. A pencil icon next to a layer or folder name in the Timeline indicates that the layer or folder is active. Only one layer can be active at a time (although more than one layer can be selected at a time). When you create a Flash document, it contains only one layer. To organize the artwork, animation, and other elements in your document, add more layers. You can also hide, lock, or rearrange layers. The number of layers you can create is limited only by your computer's memory, and layers do not increase the file size of your published SWF file. Only the objects you place into layers add to the file size. To organize and manage layers, create layer folders and place layers in them. You can expand or collapse layer folders in the Timeline without affecting what you see on the Stage. Use separate layers or folders for sound files, ActionScript, frame labels, and frame comments. This helps you find these items quickly to edit them. To help create sophisticated effects, use special guide layers to make drawing and editing easier, and mask layers. Create layers and layer folders When you create a layer or folder, it appears above the selected layer. The newly added layer becomes the active layer. Create a layer ❖ Do one of the following: • Click the Insert Layer button at the bottom of the Timeline. • Select Insert > Timeline > Layer. • Right-click (Windows) or Control-click (Macintosh) a layer name in the Timeline and select Insert Layer from the context menu.
