下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

请参阅图1，本发明实施例提供了一种批注方法，其可由批注装置来执行，并至少包括如下步骤：Referring to FIG. 1, an embodiment of the present invention provides an annotation method, which can be performed by an annotation device, and includes at least the following steps:

S101，在批注状态下，监听用户在覆盖于当前显示页面上的全局透明的编辑视图上的批注操作。S101. In the annotation state, listen to the annotation operation of the user on the global transparent edit view overlaid on the currently displayed page.

在本发明实施例中，当用户需要对打开的文档(如PPT文档、word文档等)的当前显示页面进行批注时，可点击进入批注的按钮，此时，所述批注装置在检测到用户的点击操作后，即从编辑状态切换进入批注状态，并在当前显示页面上覆盖全局透明的编辑视图，以供用户进行批注。 In the embodiment of the present invention, when the user needs to annotate the current display page of the opened document (such as a PPT document, a word document, etc.), the button for entering the annotation may be clicked. At this time, the annotation device detects the user's After clicking the operation, it switches from the edit state to the comment state, and overwrites the global transparent edit view on the current display page for the user to annotate.

在本发明实施例中，对于安卓系统，所述全局透明的编辑视图可为SurfaceView，其拥有独立的绘图表面，即不与其宿主窗口共享同一个绘图表面。由于拥有独立的绘图表面，因此SurfaceView的用户界面(User Interface，UI)就可以在一个独立的线程中进行绘制。又由于不会占用主线程资源，SurfaceView一方面可以实现复杂而高效的UI，另一方面又不会导致用户输入得不到及时响应。需要说明的是，对于不同系统，编辑视图可能有不同的名称或实现方法，但只有其实现原理或作用类似于安卓系统的SurfaceView，那么就在本发明的保护范围之内，在此不做赘述。In the embodiment of the present invention, for the Android system, the global transparent edit view may be a SurfaceView, which has a separate drawing surface, that is, does not share the same drawing surface with its host window. With a separate drawing surface, the SurfaceView's User Interface (UI) can be drawn in a separate thread. And because it does not occupy the main thread resources, SurfaceView can implement a complex and efficient UI on the one hand, and on the other hand, it will not cause the user input to get a timely response. It should be noted that, for different systems, the edit view may have different names or implementation methods, but only the implementation principle or function similar to the SurfaceView of the Android system is within the protection scope of the present invention, and will not be described herein. .

此外，需要说明的是，所述文档可以由智能平板上自带的相关软件打开并进行显示，也可以是在普通PC或笔迹本电脑上打开，并通过HDMI、VGA连接到智能平板后，显示在智能平板上，还可以是在普通PC或笔迹本电脑上打开，再通过无线传屏传输到所述智能平板上进行显示等等，本发明不做具体限定。In addition, it should be noted that the document may be opened and displayed by related software provided on the smart tablet, or may be opened on a normal PC or a handwriting computer, and connected to the smart tablet through HDMI and VGA, and then displayed. On the smart tablet, it can also be opened on a normal PC or a handwriting computer, and then transmitted to the smart tablet through a wireless screen for display, etc., and the present invention is not specifically limited.

S102，显示与所述批注操作对应的批注笔迹，并同时记录所述批注笔迹。S102. Display an annotation handwriting corresponding to the annotation operation, and simultaneously record the annotation handwriting.

在本发明实施例中，如图2所示，在生成所述编辑视图后，用户即可在所述编辑视图上进行批注操作，例如，在所述编辑视图上写字或划线(如图2中的划线01)标示出需要重点关注的内容。在用户进行批注操作的实时，所述批注装置一方面会控制显示与所述批注操作对应的批注笔迹，另一方面还同时记录所述批注笔迹。其中，这里所记录的批注笔迹至少包括以下信息：组成笔迹的每个像素点的坐标及每个像素点的颜色值。In the embodiment of the present invention, as shown in FIG. 2, after the edit view is generated, the user can perform an annotation operation on the edit view, for example, writing or scribing on the edit view (see FIG. 2). The underline 01) indicates what needs to be focused. In real time when the user performs the annotation operation, the annotation device controls on the one hand to display the annotation handwriting corresponding to the annotation operation, and on the other hand also records the annotation handwriting. Wherein, the annotation handwriting recorded here includes at least the following information: the coordinates of each pixel that constitutes the handwriting and the color value of each pixel.

S103，当检测到用户的切换操作时，将当前记录的批注笔迹保存为批注页文件，并清除绘制于所述编辑视图上的批注笔迹。S103. When the switching operation of the user is detected, the currently recorded annotation handwriting is saved as a comment page file, and the annotation handwriting drawn on the edit view is cleared.

在本发明实施例中，所述批注装置可将所述批注笔迹保存为批注页文件(如保存成XML文件)，并将所述批注页文件与所述当前显示页面形成关联，如此，当需要再次在所述当前显示页面上显示这些批注笔迹时，只需要加载保存的所述批注页文件，并将所述批注页文件中记录的批注笔迹重新绘制在所述编辑视图上即可，由于批注页文件中的批注笔迹是以像素点的形式进行保存的，因此允许用户对绘制得到的批注笔迹进而二次编辑。 In the embodiment of the present invention, the annotation device may save the annotation handwriting as an annotation page file (such as saving into an XML file), and associate the annotation page file with the current display page, so that when needed When displaying the annotation handwritings on the current display page again, only the saved annotation page file needs to be loaded, and the annotation handwriting recorded in the annotation page file is redrawn on the edit view, due to the annotation. The annotation handwriting in the page file is saved in the form of pixels, thus allowing the user to edit the drawn handwriting and then secondary editing.

需要说明的是，在本发明实施例中，所述切换操作可为翻页操作或者添加批注页操作，以下分别进行说明。It should be noted that, in the embodiment of the present invention, the switching operation may be a page turning operation or an annotation page operation, which will be separately described below.

1、所述切换操作为翻页操作1. The switching operation is a page turning operation

当用户通过点击翻页按钮进行翻页时，所述批注装置通过后台线程将当前记录的批注笔迹保存为批注页文件，同时清空编辑视图上的批注笔迹，然后跳转至目标页面。其中，在跳转到目标页面时，智能平板仍然处于批注状态，也就是说，所述目标页面上仍然覆盖有所述全局透明的编辑视图，这样用户可以直接在所述编辑视图上进行批注操作。且进一步的，如果所述目标页面之前已经有对应的已经保存的批注页文件，也可以读取所述批注页文件，将所述批注页文件中的批注笔迹重新绘制在所述编辑视图上，并进行二次编辑。When the user turns the page by clicking the page turning button, the annotation device saves the currently recorded annotation handwriting as the annotation page file through the background thread, simultaneously clears the annotation handwriting on the edit view, and then jumps to the target page. Wherein, when jumping to the target page, the smart tablet is still in the annotation state, that is, the target page is still covered with the global transparent edit view, so that the user can directly perform an annotation operation on the edit view. . And further, if the target page has a corresponding saved annotation page file before, the annotation page file may also be read, and the annotation handwriting in the annotation page file is redrawn on the edit view. And make a second edit.

2、所述切换操作为添加批注页操作2, the switching operation is to add an annotation page operation

当用户通过点击新建批注页或添加批注页来在当前显示页面上增加新的批注页时，则同样的，所述批注装置通过后台线程将当前记录的批注笔迹保存为批注页文件，同时清空编辑视图上的批注笔迹，此时，智能平板仍然处于批注状态，也就是说，所述当前显示页面上仍然覆盖有所述全局透明的编辑视图，这样用户可以直接在所述编辑视图上进行批注。在本实施例中，可以实现对同一个当前显示页面增加不同的批注页，即达到了对一屏内容进行多页批注的效果。When the user adds a new comment page to the current display page by clicking the new annotation page or adding the annotation page, the annotation device saves the current recorded annotation handwriting as the annotation page file through the background thread, and clears the editing at the same time. The annotation handwriting on the view, at this time, the smart tablet is still in the annotation state, that is, the current display page is still covered with the globally transparent edit view, so that the user can directly annotate on the edit view. In this embodiment, different annotation pages can be added to the same current display page, that is, the effect of multi-page annotation on one screen content is achieved.

综上所述，本发明实施例提供的批注方法，在用户批注过程中，记录批注笔迹，在执行切换操作时，将当前记录的批注笔迹保存为批注页文件，并清除绘制于所述编辑视图上批注笔迹。一方面，用户在翻页或者添加批注页的时候，不需要执行进入批注的操作或删除当前批注笔迹的操作就可以直接进行批注，方便了用户的操作；另一方面，由于批注页文件中的批注笔迹以数据形式保存而非图片格式保存，因而可再次在编辑视图绘制这些批注笔迹，并允许用户对绘制的批注笔迹进行二次编辑，满足了用户的使用需求，用户体验佳。In summary, the annotation method provided by the embodiment of the present invention records the annotation handwriting during the user annotation process, and saves the current recorded annotation handwriting as the annotation page file when the switching operation is performed, and clears the drawing in the editing view. Write the handwriting on the top. On the one hand, when the user flips the page or adds the comment page, the user does not need to perform the operation of entering the annotation or delete the current annotation handwriting, and the annotation can be directly performed, which is convenient for the user's operation; on the other hand, due to the annotation page file The annotation handwriting is saved in the form of data instead of the image format, so the annotation handwriting can be drawn again in the edit view, and the user can perform secondary editing on the drawn annotation handwriting, which satisfies the user's use requirements and has a good user experience.
