摘要： Systems and method for presenting a free-form drawing are described. In some aspects, a first point, a second point, and a third point from an input curve in the free-form drawing are received. A first quadratic Bezier curve is determined, where a control point of the first quadratic Bezier curve includes the second point and endpoints of the first quadratic Bezier curve include the first point and the third point. A first portion of the first quadratic Bezier curve is provided for display, where endpoints of the first portion of the first quadratic Bezier curve include the first point and a second terminal point, and where the first portion of the first quadratic Bezier curve does not include the third point.

摘要： An improved technique involves embedding a pen selection within a selected color. When a user selects a color for a new stroke by moving a cursor over a color icon, a pen palette appears within the selected color icon. In some arrangements, the improved techniques further involve automatically selecting a pen by default as the previous pen used for that color, so that only a single color selection need be made rather than separate pen and color selections. In this way, the user may then quickly and fluidly select both a color, then a pen for a drawing stroke. Such a color and pen selection process may be seen to simulate the actions in drawing on a whiteboard.
摘要翻译：一种改进的技术涉及在所选择的颜色内嵌入笔选择。当用户通过将光标移动到颜色图标上来选择新笔画的颜色时，所选颜色图标中会显示一个笔调色板。在一些布置中，改进的技术还包括自动选择笔作为用于该颜色的先前笔的笔，使得仅需要进行单个颜色选择而不是单独的笔和颜色选择。以这种方式，用户可以快速且流畅地选择颜色，然后选择笔用于绘图笔画。可以看到这样的颜色和笔选择过程来模拟在白板上绘制的动作。

摘要： An improved technique involves providing for a gesture-based undo command for use within a collaborative drawing environment. Such an undo function that is both gesture-based and capable of being used within a collaborative environment takes full advantage of the capabilities of tablet computers and laptop computers having touch screens. The gesture-based undo command may involve a multi-point linear swipe such as a two-point linear swipe gesture in order to easily distinguish an undo command from a drawing command.
摘要翻译：改进的技术涉及提供用于在协作绘图环境中使用的基于手势的撤销命令。这种基于手势和能够在协作环境中使用的撤消功能充分利用具有触摸屏的平板电脑和膝上型计算机的能力。基于手势的撤销命令可以涉及多点线性滑动，例如两点线性滑动手势，以便容易地将撤销命令与绘图命令区分开。
