在基于平面地图的插图系统中，有许多类型的插图比在更常见的基于堆叠的系统中更容易创建。所有现有的基于平面地图的系统都有一个共同的缺点，那就是一旦开始着色，绘图的可编辑性就会受到严重阻碍。定义要填充的区域的路径在相交的地方变得分开，使得很难或不可能将它们作为一个整体进行编辑。Live Paint是一种新的隐喻，它允许基于平面地图的着色，同时保持所有原始路径不变。当用户进行更改时，由新路径定义的区域和边缘将采用先前区域和边缘的填充和描边属性。这将带来更大的编辑灵活性和易用性。Live Paint使用一组启发式方法将更改后的插图中的每个区域和边缘与以前版本中的区域或边缘相匹配，这是一项比最初看起来更困难的任务。然后，它相应地传输填充和描边属性。
There are many types of illustrations that are easier to create in planar-map-based illustration systems than in the more common stacking-based systems. One weakness shared by all existing planar-map-based systems is that the editability of the drawing is severely hampered once coloring has begun. The paths that define the areas to be filled become divided wherever they intersect, making it difficult or impossible to edit them as a whole. Live Paint is a new metaphor that allows planar-map-based coloring while maintaining all the original paths unchanged. When a user makes a change, the regions and edges defined by the new paths take on fill and stroke attributes from the previous regions and edges. This results in greater editing flexibility and ease of use. Live Paint uses a set of heuristics to match each region and edge in a changed illustration with a region or edge in the previous version, a task that is more difficult than it at first appears. It then transfers fill and stroke attributes accordingly.
