Detailed Description
Example one
FIG. 1 is a flowchart illustrating a method for implementing a page turning effect of handwriting according to an embodiment of the present invention, as shown in FIG. 1, the method includes the following steps:
and S101, transmitting the handwriting anchor point information of the current reading page to the reader engine, and acquiring the canvas container of the current reading page returned by the reader engine.
When a user reads a current reading page, if the handwriting of the user exists in the current reading page, transmitting the handwriting anchor point information of the current reading page to a reader engine. The handwriting anchor point information comprises handwriting id corresponding to the current reading page, and the handwriting id indicates that the handwriting is the handwriting of the current reading page of the current electronic book. The reader engine can determine the current reading page according to the handwriting id and acquire the text information of the current reading page. And rendering the text information of the current reading page to obtain a canvas container of the current reading page. The canvas container contains the text information of the current reading page.
The canvas container of the current reading page returned by the reader engine not only contains the text information of the current reading page, but also contains the handwriting drawing starting point information, so that the handwriting position of the user during handwriting can be accurately restored when the handwriting is drawn in the canvas container. And determining the handwriting drawing starting point information according to the handwriting anchor point information. The handwriting anchor point information also comprises handwriting starting point information, and the handwriting starting point information records the position information of the first pen-drop point of the handwriting. Specifically, a coordinate system is established by taking the page turning direction of the current reading page as an abscissa axis and taking the direction perpendicular to the abscissa axis as a vertical axis, so that the position information of the first pen-down point can be accurately determined according to the coordinate position of the coordinate system. The origin of the coordinate system may be at any position in the current reading page. And establishing the same coordinate system in the canvas container as that in the current reading page, wherein the origin is consistent with that of the coordinate system in the current reading page. Preferably, any corner position of the current reading page is taken as an origin, so that when the origin of the coordinate system is established in the canvas container, the origin can be accurately positioned to be consistent with the origin of the coordinate system in the current reading page. And determining handwriting drawing starting point information in the coordinate system of the corresponding canvas container according to the handwriting anchor point information in the coordinate system of the current reading page. Or the position information of the first pen-drop point of the handwriting comprises a relative position with a certain text in the text information in the current reading page, for example, taking the first pen-drop point of the handwriting as a center, acquiring the text within a preset range of the first pen-drop point of the handwriting, and determining the text which is linearly closest to the first pen-drop point of the handwriting. The method includes the steps of recognizing a text, determining information of the text, such as recognizing the text, determining the number of pages of the text, the line number, the number of digits in the line (the number of digits of the text in the line), the position information of the text in the electronic book, and the like. And determining the position information of the first pen-falling point of the handwriting in the coordinate system by taking the text as an origin, namely the relative position information of the handwriting starting point information and the text. The method comprises the steps of firstly identifying and determining a text in a canvas container according to the information of the text, and then determining handwriting drawing starting point information in the canvas container according to the relative position information of the handwriting starting point information and the text. The handwriting drawing initial point information is determined according to the relative position information of the text and the handwriting initial point information, so that the original point is not influenced by the change of the display format of the electronic book when the handwriting is drawn conveniently, the handwriting drawing initial point information can be accurately determined through the text, and the accuracy of the handwriting drawing is guaranteed.
Further, the handwriting id is also associated with the user, and the handwriting id records the handwriting of the current user on the current reading page of the current electronic book so as to avoid confusion with the handwriting of other users, and only the handwriting of the current user is recorded on the current reading page of the current user. The handwriting id is related to the current user information, the current electronic book and the like, and is also related to the page number of the current reading page, the display format of the electronic book during handwriting and the like, and if the display format of the electronic book is changed, the page number of the current reading page corresponding to the handwriting id is correspondingly changed. The page number change is specifically determined according to the relative position information of the included handwriting starting point information and the text, and when the display format of the electronic book is changed, the page number of the text is changed, and the page number corresponding to the handwriting id is correspondingly changed into the page number of the text.
