Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As an alternative embodiment, the animation generating method provided by the present invention includes steps S100 to S300 as shown in fig. 1, and the steps S100 to S300 are described below with reference to fig. 1.
Step S100: when a first image in a template animation is displayed, second image data corresponding to an image to be displayed in the next frame of the first image is extracted from the template animation.
In an embodiment of the present invention, the template animation includes a plurality of frames of images. Specifically, when the first image in the template animation is displayed, an analog signal corresponding to an image to be displayed in the next frame is simultaneously acquired, and image data is obtained according to the analog signal, wherein the image data includes characteristics of the analog signal. Here, the analog signal may be sound.
In order to realize the animation effect, the system needs to refresh and update the images constituting the animation effect, wherein the animation effect is called the animation effect, and the template animation refers to an image sequence composed of the images constituting the animation effect. In the prior art, the frame rate of a system for refreshing a dynamic effect picture is fixed, the system needs to redraw and render image data corresponding to all images in a template animation in order to refresh the dynamic effect picture, the system has a large calculation amount, on one hand, the system consumes large energy, on the other hand, a pause phenomenon easily occurs when the system consumes large energy, and after the system generates the pause phenomenon, the system stops drawing and rendering the images, and at the moment, the pause phenomenon easily occurs on the dynamic effect picture.
However, in fact, on the one hand, when the animation is presented, not all images in all animation pictures are changed, and at this time, only the image data corresponding to the changed images need to be redrawn and rendered. On the other hand, when the frame rate is low and a good animation effect can be achieved, the image data corresponding to all the images in the template animation does not need to be redrawn and rendered, the image data corresponding to the partial images in the template animation can be selected to be redrawn and rendered, and the redrawn and rendered images are displayed according to the set frame rate, so that the animation effect can be achieved, and the system performance can be saved. Specifically, please refer to step S200.
Step S200: and performing image drawing on the second image data through a drawing instruction to obtain a drawn second image.
Drawing instructions are instructions that may cause a module that implements image drawing to be invoked.
In the embodiment of the present invention, a specific implementation manner of performing image rendering on the second image data through the drawing instruction to obtain a rendered second image is as follows: triggering a drawing instruction, and acquiring drawing parameters corresponding to the second image data according to the second image data; and responding to the drawing instruction, and drawing the second image data according to the drawing parameters to obtain the second image. Wherein the image rendering the second image data according to the rendering parameter to obtain the second image includes: calling a drawing instruction corresponding to the second image data; acquiring a target canvas corresponding to the second image data; and responding to the drawing instruction, and drawing the second image data on the target canvas by using the drawing parameters.
In the embodiment of the present invention, the canvas corresponding to the second image data is obtained, and a target canvas corresponding to the second image data is selected from the plurality of canvases that have been created. Here, the template animation includes a plurality of image data, each of which corresponds to one of the created canvases. The drawing instruction comprises the identification of the canvas corresponding to the second image data, and the drawing instruction acquires the target canvas corresponding to the second image data according to the identification.
As an embodiment, in an Android (Android) system, the drawing instruction may correspond to an abstract class of View in the Android system, the canvas may correspond to an abstract class of Layer in the Android system, the canvas corresponding to the second image data is selected by the drawing instruction, and a specific implementation manner in the Android system may be implemented by View.
Wherein both View and Layer act as canvas for realizing image drawing. Generally, views and layers are located in different levels in Android, views correspond to Java language program levels of the Android, layers correspond to C language program levels of the Android, and in the Android system, energy consumption for drawing images by using the layers is lower than that of drawing images by using views. For an Android system, in the prior art, a Layer is applied by calling a surfefinger class of which a service is responsible for drawing an Interface (User Interface, UI) of an Android application program, but the application of the Layer based on the surfefinger class generally applies for the number of the layers corresponding to the number of images according to the number of the images corresponding to image information transmitted into the surfefinger, and when the images are drawn, the layers simultaneously draw the images, so that energy consumption is high, and system blockage is easily caused.
In the embodiment of the present invention, the drawing parameters may be delivered via a network, or acquired in real time, or pre-stored in the system. Here, the drawing parameters include a rotation parameter, a translation parameter, a zoom parameter, a fade parameter, and the like. The rotation parameter is used for realizing the rotation dynamic effect of the dynamic effect picture, the translation parameter is used for realizing the dynamic effect of the translation motion of the dynamic effect picture, the zooming parameter is used for realizing the reduction or amplification dynamic effect of the dynamic effect picture, and the gradual change parameter is used for realizing the gradual change dynamic effect of the color, brightness or shape degree of the dynamic effect picture. Specifically, the second image data corresponding to each frame of image in the effective picture is changed according to the drawing parameters, so that the image is changed, and the animation effect is further realized.
Step S300: displaying the second image on a display screen displaying the first image.
By displaying the first image and then displaying the second image in the next frame, an animation effect can be produced on the display screen.
In an embodiment of the present invention, before displaying the second image on the display screen displaying the first image, the method further includes: rendering the second image.
As an embodiment, in the Android system, the second image may be rendered by a surfefinger class, and the rendered second image is displayed.
As an example, when the first image is a two-frame image in the animation, after the first image is displayed, a third frame image of the animation needs to be displayed. The template animation stores image data a corresponding to a third frame image, image data B corresponding to a fourth frame image, image data C corresponding to a fifth frame image, and the like. When the first image in the template animation is displayed, the image data a is extracted from the template animation as target image data (i.e., second image data), and image drawing and rendering are performed according to the image data a, so that a third frame image (i.e., the second image) to be displayed is obtained. When the second image is displayed, image data B is extracted from the template animation as target image data, image drawing and rendering are carried out according to the image data B, namely, a fourth frame image needing to be displayed is obtained, when the fourth frame image is displayed, image data C is extracted from the template animation as target image data, and image drawing and rendering are carried out according to the image data C, namely, a fifth frame image needing to be displayed is obtained. Thus, the animation effect is realized.
By adopting the scheme, when the first image in the template animation is displayed, the second image data corresponding to the image to be displayed in the next frame of the first image is extracted from the template animation, the second image data is subjected to image drawing through the drawing instruction to obtain the drawn second image, and the second image is displayed on the display screen displaying the first image. The image data corresponding to all the images in the template animation is not required to be processed, the second image data corresponding to the image to be displayed in the next frame is selectively extracted, the second image data is subjected to image drawing through the drawing instruction to obtain the drawn second image, and the second image is displayed on the display screen displaying the first image, so that the animation effect can be realized. The technical problem of large system performance consumption in the prior art is solved, and the technical effect of reducing the system energy consumption is achieved.
