特殊效果
出自OOo 中文指南手册翻译
在Draw中,你可以向对象和对象组合应用很多特殊效果。本节描述了这些效果中的一些。其他的包括扭曲、阴影和透明度,许多可用效果的例子,参见Draw指南。 With Draw, you can apply many special effects to objects and groups of objects. This section describes a few of these effects. Others include distorting, shadows, and transparency. See the Draw Guide for examples of the many effects available. (1)

[编辑] 翻转对象
选中一个对象,然后单击“翻转”按钮
,你会看到一条虚线从中间穿过对象。
这条虚线就是对象的对称轴。对象就以对称轴作反射的,用鼠标移动轴的一个或全部端点可以设置轴的倾向角度。
然后用鼠标拖拽八个绿色手柄的任意一个,移动到轴线的另一端,移动过程中对象是以虚线形式显示的,释放鼠标,对象翻转结束。
注意:如果你在移动轴线时同时按住“shift”键,轴线将以45度为增量作旋转。
[编辑] 镜像复制
正式的说,在绘图中是没有这条命令的。但是,镜像复制功能很容易仿真实现。
将对象对称轴移到理想位置作镜象轴,选中对象并复制到粘贴板,翻转对象,然后在空白区域单击释放选中对象。从粘贴板中粘贴原始对象到对象原来位置,现在就完成了镜像复制。
[编辑] 扭曲图像 Distorting an image (14)
在效果菜单上有三种工具,让你拖动对象的角和边缘来扭曲相应的图像。 There are three tools on the Effects menu that let you drag the corners and edges of an object to distort the image. (15)
其中的'扭曲工具整体扭曲一个对象,而设置到圆(倾斜)和设置在圆内(透视)工具,均产生一个伪三维效果。见第4章绘制指南'的细节。 The Distort tool distorts an object in perspective, the Set to Circle (slant) and Set in Circle (perspective) tools both create a pseudo three-dimensional effect. See Chapter 4 of the Draw Guide for details. (16)
[编辑] 动态渐变 Dynamic gradients (17)
您可以象控制色彩渐变一样来控制透明度渐变。这两种类型的渐变可以一起使用。对于透明度梯度,对象填充颜色的方向和程度从不透明变化到透明(在常规渐变中,填充颜色从一个颜色变化到另一个,但透明度保持不变)。详见见Draw指南第4章。 You can control transparency gradients in the same manner as color gradients. Both types of gradient can be used together. With a transparency gradient, the direction and degree of an object’s fill color changes from opaque to transparent (in a regular gradient, the fill changes from one color to another, but the degree of transparency remains the same). See Chapter 4 of the Draw Guide for details. (18)
[编辑] 复制 Duplication (19)
复制在对一个对象应用一系列变化(如颜色或旋转)的同时产生一个副本。一个复制的结果是一个新的组合。 Duplication makes copies of an object while applying a set of changes (such as color or rotation) to the duplicates. The result of a duplication is a new group. (20)
要开始复制,点击一个对象或组合,并选择编辑 > 复制。如下所示的对话框出现。 To start duplication, click on an object or group and choose Edit > Duplicate. The dialog shown below appears. (21)
将以上选项应用于一个蓝色矩形产生以下的结果。 The options above applied to a blue rectangle produce the following result. (23)
[编辑] 变形过渡 Cross-fading (25)
变形过渡将一种形状转换成另一种形状,OpenOffice.org处理所有的中间过渡。其结果是一个新的对象组合,包括起点形状、终点形状和相应的中间步骤。 Cross-fading transforms a shape from one form to another, with OpenOffice.org handling all of the intermediate transitions. The result is a new group of objects including the two end points and the intermediate steps. (26)
要进行变形过渡,选择相应的两个对象(按住Shift移键,同时依次选择每个对象),然后选择编辑 > 变形过渡,将出现以下对话框。 To carry out a cross-fade, select both objects (hold the Shift key while selecting each object in turn) and then choose Edit > Cross-fading The following dialog appears. (27)
在对话框中选择递变的数量(过渡的步骤)。你可能希望选择变形过渡属性和同一方向复选框。最终的结果如下所示。 On the dialog choose the number of increments (transition steps). You probably want to have Cross-fade attributes and Same orientation both checked. The end result is shown below. (29)
