REVERSIBLE DIGITAL INK FOR INKING APPLICATION USER INTERFACES

Systems, methods, and software are disclosed herein for supporting reversible ink in a user interface to an application. In an implementation, an application receives inking input on a canvas in a user interface to the application. The application renders ink on the canvas along a path taken by the inking input and monitors for the inking input to reverse direction along the path. In response to the inking input reversing the direction along the path, the application erases at least a portion of the ink from the canvas. 本文公开了用于在应用的用户界面中支持可反转墨水的系统、方法和软件。在一种实施方式中，应用在应用的用户界面中的画布上接收着墨输入。应用沿着着墨输入所采用的路径在画布上呈现墨水，并监测着墨输入以沿着路径反转方向。响应于着墨输入沿着路径反转方向，应用从画布上擦除至少一部分墨水。
