Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a face frame drawing method of the present invention, where the method includes:
step S10, obtaining path data corresponding to the face frame design manuscript picture;
the face frame drawing method is applied to mobile terminals such as smart phones and tablet computers. Firstly, a mobile terminal acquires Path data corresponding to a face frame design draft picture, wherein the Path data is data used for vector drawing, a class is called as Path in the drawing process of user-defined view (view), the Path can be used for drawing not only simple graphs (such as circles, rectangles, straight lines and the like) but also complex graphs (such as regular polygons, pentagons and the like), and the Path can be used for drawing, cutting and drawing texts.
In an embodiment, the step S10 may include: acquiring a face frame design draft picture; converting the face frame design draft picture into a Scalable Vector Graphics (SVG) picture, and converting the SVG picture into a corresponding configuration file; and analyzing the configuration file to obtain path data corresponding to the face frame design draft picture.
Specifically, the mobile terminal first obtains a pre-designed face frame design draft picture, the face frame design draft picture may be designed by a developer or customized by an external partner, and the present embodiment does not limit features such as color and style of the face frame design draft picture. After the face frame design draft picture is acquired, the mobile terminal can convert the face frame design draft picture into a Scalable Vector Graphics (SVG) picture through preset picture processing software such as photoshop, wherein the SVG is a graphics format based on an extensible markup language and used for describing two-dimensional Vector graphics; then, converting the SVG picture into a corresponding configuration file through an integrated development tool of the mobile terminal, for example, for an Android mobile phone, converting the SVG picture into a corresponding XML (Extensible Markup Language) configuration file through an integrated development tool Android Studio of the mobile terminal, where the configuration file includes path data; and then analyzing the converted configuration file to obtain path data corresponding to the face frame design manuscript picture.
Further, the step of obtaining the face frame design draft picture may include: reading a face frame design draft picture which is pre-stored in the local mobile terminal; or receiving a face frame design draft picture sent by an external terminal; or, downloading the face frame design draft picture from the Internet.
In this embodiment, the mobile terminal may obtain the face frame design draft picture in a variety of ways, including reading a face frame design draft picture pre-stored locally in the mobile terminal, receiving a face frame design draft picture sent by an external terminal (e.g., a computer, a mobile phone, a tablet computer, etc.), downloading the face frame design draft picture from the internet, and the like, and in particular, different face frame design draft picture obtaining ways may be flexibly selected.
In another embodiment, when the mobile terminal obtains the path data corresponding to the face frame design draft picture, an external terminal (e.g., a computer, a mobile phone, a tablet computer, etc.) may convert the face frame design draft picture into the corresponding path data, and then send the converted path data to the mobile terminal, where the mobile terminal directly receives the path data corresponding to the face frame design draft picture sent by the external terminal.
Step S20, analyzing the path data to obtain the center point and the size of the picture of the face frame design draft;
in this step, the mobile terminal analyzes the acquired path data to obtain a central point and a size of the picture of the face frame design draft, where the central point may be represented in a form of coordinates, such as position coordinates of the central point in a mobile terminal screen, and the size may be represented in a form of resolution, such as 800 × 640.
Step S30, calculating the translation distance of the center point translated to the center of the screen of the mobile terminal according to the center point of the face frame design draft picture;
in this embodiment, in order to enable the user-defined face frame control to adapt to the screen sizes of different mobile terminals, an original face frame design draft picture needs to be adjusted, specifically, the face frame design draft picture is translated to the center of a mobile terminal screen, and then the face frame design draft picture is scaled in an equal ratio to cover the whole screen of the mobile terminal.
Firstly, calculating the translation distance of the center point translated to the center of the screen of the mobile terminal according to the center point of the face frame design draft picture, specifically, acquiring the center point coordinate of the face frame design draft picture and the center coordinate of the screen of the mobile terminal, and then obtaining the translation distance of the center point of the face frame design draft picture translated to the center of the screen of the mobile terminal according to the distance between the two coordinates.
Step S40, calculating the scaling of the face frame design draft picture when the face frame design draft picture is scaled to cover the whole screen of the mobile terminal according to the preset rule in an equal ratio mode according to the size of the face frame design draft picture;
and then, according to the size of the face frame design draft picture, calculating the scaling of the face frame design draft picture when the face frame design draft picture is scaled to cover the whole screen of the mobile terminal in an equal ratio according to a preset rule. Specifically, when the size of the face frame design manuscript picture is larger than the size of the screen of the mobile terminal, the face frame design manuscript picture needs to be scaled down, and when the size of the face frame design manuscript picture is smaller than the size of the screen of the mobile terminal, the face frame design manuscript picture needs to be scaled up. The scaling rule corresponding to the face frame design draft picture being scaled to cover the whole screen of the mobile terminal in an equal ratio may be: and the face frame design draft picture is zoomed to just cover the whole screen of the mobile terminal in an equal ratio, and then zooming is stopped, or the face frame design draft picture is zoomed to just cover the whole screen of the mobile terminal in an equal ratio and then is amplified according to a preset ratio. The specific scaling rule and the preset ratio can be flexibly selected by a developer.
It should be noted that, the scaling is performed in an equal ratio, that is, the width and the height of the face frame design draft picture are scaled according to the same ratio, and in the process of scaling in an equal ratio, the center point of the face frame design draft picture is always overlapped with the center of the screen of the mobile terminal.
And step S50, performing path self-drawing according to the path data, the translation distance and the scaling ratio to obtain a user-defined face frame control.
In the step, the mobile terminal carries out path self-drawing according to the obtained path data, the translation distance and the scaling ratio, and the user-defined face frame control is obtained. Specifically, a preset drawing function may be called, a corresponding original face frame design draft picture is drawn according to the path data, and then the original face frame design draft picture is translated and scaled in an equal ratio according to the translation distance and the scaling ratio, so as to finally obtain the user-defined face frame control. It should be noted that, when the aspect ratio of the face frame design draft picture is different from the aspect ratio of the mobile terminal screen, the face frame design draft picture may have a portion exceeding the mobile terminal screen after being zoomed, at this time, the portion exceeding the mobile terminal screen needs to be cut off, and then the customized face frame control is generated according to the cut picture.
Through the mode, the translation distance and the scaling ratio of the face frame design draft picture are firstly calculated in the embodiment, then the customized face frame control is obtained by adopting a path self-drawing mode, the obtained customized face frame control can adapt to the screen sizes of different mobile terminals, and different external partners can perform customized operation.
Further, a second embodiment of the face frame drawing method of the present invention is proposed based on the first embodiment of the face frame drawing method of the present invention.
In this embodiment, the step S40 may further include: acquiring the screen size of the mobile terminal; and calculating the scaling ratio of the face frame design draft picture when the face frame design draft picture is scaled to cover the whole screen of the mobile terminal in an equal ratio after the central point of the face frame design draft picture is translated to the center of the screen of the mobile terminal according to the size of the screen of the mobile terminal and the size of the face frame design draft picture.
Specifically, when calculating the scaling, first obtaining the screen size of the mobile terminal, which may be expressed in the form of resolution, such as 1920 × 1080; and then, calculating the scaling ratio when the center point of the face frame design draft picture is translated to the center of the screen of the mobile terminal, and cutting off the part which exceeds the whole screen of the mobile terminal after scaling when the face frame design draft picture is scaled to cover the whole screen of the mobile terminal. The face frame design draft picture obtained by the zooming rule further reduces the memory occupied by the face frame design draft picture on the premise of ensuring that the face frame design draft picture is adaptive to the screen size of the mobile terminal.
Further, the step S50 may include: generating a graph transformation matrix according to the translation distance and the scaling; creating a canvas, and drawing a corresponding face frame design draft picture on the canvas according to the path data; translating and scaling the drawn face frame design draft picture in an equal ratio according to the graph transformation matrix, and cutting off the part of the face frame design draft picture exceeding the whole screen until the face frame design draft picture is scaled in an equal ratio to cover the whole screen of the mobile terminal; and generating a user-defined face frame control according to the cut face frame design manuscript picture.
Specifically, when the path is self-drawn, the mobile terminal may generate a graph transformation Matrix according to the calculated translation distance and the scaling, then create a canvas, draw a corresponding face frame design draft picture on the canvas according to the path data, then translate and scale the drawn face frame design draft picture according to the graph transformation Matrix, until the face frame design draft picture is scaled to cover the whole screen of the mobile terminal in an equal ratio, cut off the part of the face frame design draft picture exceeding the whole screen, and then generate a user-defined face frame control according to the cut face frame design draft picture.
The step of generating a user-defined face frame control according to the cut face frame design manuscript picture may further comprise: and reducing the cut face frame design draft picture according to a preset proportion, and generating a user-defined face frame control according to the reduced face frame design draft picture.
In an actual application scene such as face recognition, because a face frame is generally smaller than a mobile terminal screen, a mobile terminal can reduce a cut face frame design draft picture according to a preset proportion, and then a user-defined face frame control is generated according to the reduced face frame design draft picture, wherein the reduction is in aspect ratio such as width, and the reduced proportion can be flexibly set according to actual needs. By the method, the design draft of the face frame meets the requirements of practical application scenes, and the memory occupied by the finally generated user-defined face frame control is further reduced.
Of course, in this embodiment, the mobile terminal may also generate the user-defined face frame control directly according to the size of the cut face frame design draft picture without performing reduction processing on the cut face frame design draft picture, and the user-defined face frame control may be flexibly set during specific implementation.
Further, a third embodiment of the face frame drawing method of the present invention is proposed based on the first and second embodiments of the face frame drawing method of the present invention.
In this embodiment, after step S50, the method may further include: and integrating the user-defined face frame control into a software development kit, and issuing the software development kit.
In this embodiment, the final purpose of drawing the custom face box control is to provide the custom face box control for an external partner, and for this reason, the mobile terminal may integrate the drawn custom face box control into a software development kit SDK, and then release the software development kit. External partner can be integrated to the APP of self development with the SDK package that is integrated with self-defined face frame to possess the APP of face identification function as an example, when the user uses this APP to carry out face identification through mobile terminal, mobile terminal shows self-defined face frame control in application interface, the user can be according to the colour, the style etc. of self-defined face frame control of own needs, thereby satisfy user's individualized demand.
Compared with the prior art, developers do not need to design face frame pictures with various colors and styles, and only need to integrate the user-defined face frame control into the SDK package for publishing, so that the development and maintenance cost of the face frame pictures is reduced.
