又称形状补间，即通过补充两个关键帧间的形状，创建类似于形变的效果，使一种图形随时间变化成为另一种图形。可以改变形状的位置、大小及颜色。TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE形状渐变动画

使用选择工具将图形对象全部选中，若选择的图形对象为点状色表示（内部布满小白点），没有边框包围，它就是矢量图；若选择的图形对象被麻绳包围，它就是位图；若选择的图形对象被蓝色的细线包围，它就是元件实例或组合体。判断方法TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE形状渐变动画

形状渐变动画的变形对象必须是矢量图形。注意事项TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE形状渐变动画

要将文本分离成图形，需要执行2次分离操作，第一次是将文本分离成单个的文字，第二次是将文字分离成矢量图形。分离的快捷键（Ctrl+B）分离TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE形状渐变动画转换位图为矢量图修改—位图—转换位图为矢量图分离TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE形状渐变动画1、制作第一个关键帧；（如果对象不是图形或矢量图，需要转换）2、制作第二个关键帧；（如果对象不是图形或矢量图，需要转换）3、选择开始帧和结束帧中间的任何一帧，在属性面板中选择形状补间。制作方法TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE形状渐变动画1、至少存在两个不连续的关键帧；2、关键帧中的对象必须的图形或矢量图，即散件；3、设置形状补间。必要条件TEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERETEXTHERE
