    • A computer-implemented method alters component colors of art work associated with a drawing stroke on an electronic document. In one aspect, the invention generates a darkness value for each component color of each original color; generates a new color to substitute for each original color, the component color values of the new color being generated according to the corresponding darkness value and a reference color; and alters the component colors of the art work based on the new color values. In a second aspect, the invention provides a computer-implemented method for altering a component color of art work by mapping the component color to a new color based on a color space associated with the component color and applying the resulting color to components of the art work. In a third aspect, the computer-implemented method for altering component colors of the art work includes converting the color of components into a hue, saturations and brightness (HSB) color space; biasing hue values of a key color, a paint color, and a stroke color; mapping the hue values; transforming saturation and brightness values; unbiasing the hue values; converting the resulting color into original color space of the stroke color; and applying the resulting color to components of art work stroke derived from the components of the base art work.
    • 计算机实现的方法改变与电子文档上的绘图笔画相关联的艺术作品的分量颜色。 一方面,本发明为每种原色的每个分量颜色生成暗度值; 产生新颜色以代替每个原始颜色,根据相应的暗度值和参考颜色生成新颜色的分量颜色值; 并基于新的颜色值来改变艺术作品的组件颜色。 在第二方面,本发明提供了一种计算机实现的方法,用于通过基于与分量颜色相关联的颜色空间将组件颜色映射到新颜色并将所得到的颜色应用于本领域的组件来改变艺术作品的组件颜色 工作。 在第三方面,用于改变艺术作品的组分颜色的计算机实现的方法包括将分量的颜色转换为色调,饱和度和亮度(HSB)颜色空间; 键颜色,油漆颜色和笔画颜色的偏移色调值; 映射色调值; 转换饱和度和亮度值; 不偏爱色调值; 将所得到的颜色转换成笔画颜色的原始颜色空间; 以及将所得到的颜色应用于从艺术作品的组成部分得到的艺术作品中的元素。

    • Techniques for assigning a subpath attribute to a subpath in a drawing are disclosed. One technique includes editing the drawing to define a current path having a current subpath, matching a previous vertex in a previous path with a current vertex in the current path, and assigning a current subpath attribute to the current subpath based on the vertex match. Another technique includes editing the drawing to define a current path having a current subpath, comparing the current subpath with a previous subpath having a previous subpath attribute, and assigning a previous subpath attribute to the current subpath based on the comparison.
    • 公开了将子路径属性分配给图形中的子路径的技术。 一种技术包括编辑图形以定义具有当前子路径的当前路径,将先前路径中的先前顶点与当前路径中的当前顶点匹配,以及基于顶点匹配将当前子路径属性分配给当前子路径。 另一技术包括编辑图形以定义具有当前子路径的当前路径,将当前子路径与具有先前子路径属性的先前子路径进行比较,以及基于比较将先前子路径属性分配给当前子路径。

    • Methods and apparatus implementing a technique for positioning and editing graphical elements repeated along a path in an electronic document. The technique includes creating an enhanced path, which has a graphical element, a path, and a set of one or more reproduction parameters specifying how copies of the element are to be displayed along the path; drawing copies of the element in an electronic document according to the enhanced path; allowing a user to edit the enhanced path; and redrawing copies of the element according to the edited enhanced path.
    • 实现用于定位和编辑沿着电子文档中的路径重复的图形元素的技术的方法和装置。 该技术包括创建增强路径,其具有图形元素,路径和一组一个或多个再现参数,其指定如何沿路径显示元素的副本; 根据增强路径在电子文档中绘制元素的副本; 允许用户编辑增强的路径; 并根据编辑的增强路径重新绘制元素的副本。
