All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides an image rendering method, an image rendering device, electronic equipment and a storage medium. Specifically, the embodiment of the present invention provides an image rendering method suitable for an image rendering apparatus, which may be integrated in an electronic device.
The electronic device may be a terminal or other devices, including but not limited to a mobile terminal and a fixed terminal, for example, the mobile terminal includes but is not limited to a smart phone, a smart watch, a tablet computer, a notebook computer, a smart car, and the like, wherein the fixed terminal includes but is not limited to a desktop computer, a smart appliance such as a smart television, and the like.

The image rendering method of the embodiment of the invention can be realized by a terminal, and can also be realized by the terminal and a server together.
The method is described below by taking an example in which the terminal and the server implement the image rendering method together.
As shown in fig. 1, an image rendering system provided by the embodiment of the present invention includes a terminal 10, a server 20, and the like; the terminal 10 and the server 20 are connected via a network, for example, a wired or wireless network connection, wherein the terminal 10 may exist as a terminal for sending an image rendering request to the server 20.
Among them, the terminal 10 may be a terminal generating an image rendering request for transmitting the image rendering request to the server 20.
The server 20 may be configured to store a rendering code file, and after receiving the image rendering request sent by the terminal 10, may send the rendering code file corresponding to the image rendering request to the terminal 10 according to the image rendering request.
The terminal 10 may be configured to obtain a rendering code file corresponding to a target image effect, parse the rendering code file to obtain rendering information and a rendering parameter calculation function corresponding to the target image effect, call the rendering parameter calculation function, calculate an image rendering parameter corresponding to the target image effect based on the rendering information, and perform image rendering based on the image rendering parameter to obtain an image with the target image effect.
After obtaining the image having the target effect, the terminal 10 may display the image having the target image effect.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
The embodiment of the present invention will be described from the perspective of an image rendering apparatus, which may be specifically integrated in a terminal.
As shown in fig. 2, a specific flow of the image rendering method of the present embodiment may be as follows:
201. and acquiring a rendering code file corresponding to the target image effect.
The target image effect may be an image that the user specifies to be displayed on the terminal and/or a rendering effect that the image has, for example, image a in image A, B, C may be specified by the user to be displayed on the terminal while setting a special effect of adding a lighting effect to an edge of the image for image a, an image a whose edge has a lighting effect, and so on.
Alternatively, the target image effect may be an image displayed on the image and/or a rendering effect that the image has set by the technician, for example, the technician may set that after the terminal does not receive any trigger operation for 3 minutes, the dynamic image a is displayed in a preset image display area of the terminal, the target image effect is the dynamic image a is displayed in the preset image display area, and so on.
In some examples of the embodiment of the present invention, the rendering code file may be a code file written by a technician according to an image rendering requirement, and it may be understood that the rendering code file may include not only program codes that can be executed, but also rendering information that is required when an image is rendered, and the like.
In the actual use process, a corresponding rendering code file can be set for each image effect, and after a target image effect is determined from multiple image effects, the rendering code file corresponding to the target image effect can be acquired. That is, before the step "obtaining the rendering code file corresponding to the target image effect", the image rendering method provided in the embodiment of the present invention further includes:
acquiring an image rendering request, wherein the image rendering request comprises a target image effect identifier;
and determining the target image effect corresponding to the target image effect identifier based on the corresponding relation between the preset image effect identifier and the image effect.
The image rendering request can be triggered by the operation of a user or generated by the terminal. For example, the image rendering request may be generated by operation triggering such as clicking and sliding by a user, or the image rendering request may be automatically generated by the terminal at set time intervals when a technician sets a certain target image effect to be displayed at fixed time, and so on.
In some alternative embodiments, the image effect identifier may be a mark that serves as an identifier for the image effect, for example, the image effect identifier may be a name corresponding to a different image effect, for example, the image identifier may be "image B with a luminous effect at an image edge", or the image effect identifier may be a preset label corresponding to a different image effect, for example, the image effect of "image B with a luminous effect at an image edge" may be preset to be effect 1, "image C with a luminous effect at an image edge" may be preset to be effect 2, and then the image identifier may be 1, 2, and so on.
For example, the technician may preset the correspondence between the image effect identifier and the image effect to be: the image effect of the "image B with a light-emitting effect at an image edge" is effect 1, the image effect of the "image C with a light-emitting effect at an image edge" is effect 2, the image effect of displaying the moving image a in the preset image display area is effect 3, the target image effect identifier in the image rendering request is 3, the target image effect may be determined to be displaying the moving image a in the preset image display area according to 3, and so on.
It is understood that the rendering code file corresponding to the target image effect may be one file, for example, the image effect of the image B with the light-emitting effect at the edge of the image corresponds to only one rendering code file, or the rendering code file corresponding to the target image effect may also be two or more files, for example, the image effect of the image B with the light-emitting effect at the edge of the image may correspond to the rendering code file of one image B and the rendering code file with the light-emitting effect at the edge of the image, respectively, and so on.
That is, the image effect may be split, and when the rendering code file is determined, at least two corresponding code files may be determined according to the target image effect, so as to further save storage resources of the rendering code file. For example, a first rendering code file corresponding to an image and a second rendering code file corresponding to other effects may be set. Step 201 may include: and acquiring a first rendering code file and a second rendering code file corresponding to the target image effect.
For example, image a corresponds to a first rendering code file a, image B corresponds to a first rendering code file B, image edges having a lighting effect correspond to a second rendering code file 1, and image edges having a blinking effect correspond to a second rendering code file 2. When it is determined that the target image effect is an image B whose image edge has a lighting effect, the first rendering code file B and the second rendering code file 1 are acquired, and so on. By combining the rendering code files, each target image effect does not need to correspond to one rendering code file, the requirements on storage resources, transmission resources and computing resources are further reduced, and the image rendering cost is saved.
202. And analyzing the rendering code file to obtain rendering information and a rendering parameter calculation function corresponding to the target image effect.
The rendering information may be information required in the image rendering process, such as which range, which position, what time point and/or what color is displayed in the display area of the terminal, and the like.
The rendering parameter calculation function may be a function that calculates an image rendering parameter required in an image rendering process based on the rendering information. For example, the rendering information may be information of which range, which position, what time point, and/or what color is displayed in a display area of the terminal, and the rendering information may be converted into specific rendering parameters through calculation of a rendering parameter calculation function, and the terminal may implement image rendering according to the obtained rendering parameters.
Specifically, the process of analyzing the rendering code file may be a process of performing operations such as file stream reading and storing on the obtained rendering code file by the terminal. For example, the terminal may download a rendering code file corresponding to the target image effect from the server, and the process of parsing the rendering code file may include: and reading the content in the rendering code file stored in the terminal disk after downloading through a byte input stream technology, such as an inputstream technology in Java, storing the read content in a memory of the terminal, and the like.
In some optional examples, the rendering information and the rendering parameter calculation function may be subfiles of the rendering code file, respectively, and the rendering information and the rendering parameter calculation function corresponding to the target image effect may be obtained by parsing the subfiles of the rendering code file.
In other optional examples, the rendering information and the rendering parameter calculation function may be stored in the same code file, and at this time, the character string parsed from the code file needs to be further parsed to obtain the rendering information and the rendering parameter calculation function corresponding to the target image effect. That is, step 202, may include:
analyzing the rendering code file to obtain a character string in a preset format;
and analyzing the character string to obtain rendering information and a rendering parameter calculation function corresponding to the target image effect.
The process of parsing the character string may be a process of dividing the character string according to a marker in the character string, for example, identification information or a keyword may be set for the rendering information and the rendering parameter calculation function, and when the character string is read, the read content may be determined as the rendering information or the rendering parameter calculation function according to the read identification information and/or the read keyword.
For example, in the actual use process, the codes of the functions may be calculated in advance for different rendering parameters, different program class names may be set according to different calculation functions, the functions may be calculated according to different class names and different rendering parameters at the parsing position when the character string is parsed, and the like.
It can be understood that the character string may be a character string obtained by reading a character in a rendering code file, and because a code in the rendering code file is written after a developer selects an image rendering interface and a program language for image rendering according to an image rendering requirement, the code in the rendering code file should be in a code form required by a review language specification, an interface specification, and the like, a format of the character string may be understood as a format in which the character in the character string also meets a preset requirement.
For example, a technician may use an OpenGL (Open Graphics Library) interface and a GLSL (OpenGL rendering Language), the format of the string should be a format that satisfies the OpenGL and GLSL specifications, and so on.
203. And calling a rendering parameter calculation function, and calculating an image rendering parameter corresponding to the target image effect based on the rendering information.
In some optional examples, the rendering information may include rendering position information, rendering size information, and rendering color information, and the rendering parameter calculation function may include a position calculation function, a size calculation function, and a color calculation function.
Correspondingly, the step of invoking a rendering parameter calculation function and calculating an image rendering parameter corresponding to the target image effect based on the rendering information may specifically include:
calling a position calculation function, and calculating rendering position parameters corresponding to the target image effect based on the rendering position information;
calling a size calculation function, and calculating rendering size parameters corresponding to the target image effect based on the rendering size information;
calling a color calculation function, and calculating rendering color parameters corresponding to the target image effect based on the rendering color information;
and obtaining an image rendering parameter corresponding to the target image effect based on the rendering position parameter, the rendering size parameter and the rendering color parameter.
The rendering position information is information for determining an image rendering position in an image rendering process, and may be, for example, which position of a center point of an image is in a display area of the terminal, and the like. The position calculation function may be a function that calculates a rendering position parameter indicating a rendering position of the image during the image rendering process based on the rendering position information.
The rendering size information is information for determining a rendering size of the image during the image rendering process, and may be, for example, determining a size of the image, or the like. The size calculation function may be a function that calculates a rendering size parameter indicating a rendering size of the image during the image rendering process based on the rendering position information.
For example, the rendering size information may be determined according to the model of the terminal (e.g., mobile phone, smart tv, etc.), such as the same moving picture, the display size on the mobile phone may be 300 × 500 pixels, and the display size on the smart tv may be 1080 × 2000 pixels, and so on.
The rendering color information is information for determining an image rendering position during image rendering, and may be, for example, which position of a center point of an image is in a display area of the terminal. The color calculation function may be a function of calculating a rendering color parameter indicating a rendering color of the image during the image rendering process based on the rendering position information.
For example, the rendering color information may indicate which color a certain pixel in the image is, or indicate which regions in the image are, and so on.
In some specific embodiments, the rendering position parameter, the rendering size parameter, and the rendering color parameter may be directly used as the image rendering parameter, or the image rendering parameter may be generated after determining the corresponding relationship among the position, size, and color of the image according to the rendering position parameter, the rendering size parameter, and the rendering color parameter, and so on. For example, the correspondence between the position, size, and color of the image may be that the center point of the image is the center of the circle, a circle of radius 10 pixels is red, and so on.
In the practical application process, a dynamic image can be displayed on the terminal, or the image is refreshed at regular time, or the image displayed on the terminal is replaced at regular time, and the like, so that time-related information can be further included in the rendering code file. That is, the step of "analyzing the rendering code file to obtain the rendering information and the rendering parameter calculation function corresponding to the target image effect" may include:
analyzing the rendering code file to obtain rendering time information, rendering information and a rendering parameter calculation function corresponding to the target image effect;
correspondingly, the step of invoking the rendering parameter calculation function and calculating the image rendering parameter corresponding to the target image effect based on the rendering information may include:
and calling a rendering parameter calculation function, and calculating the image rendering parameters corresponding to the target image effect based on the rendering time information and the rendering information.
Wherein the rendering time information is time information related to image rendering. For example, the rendering time information may be how often the rendering parameter calculation function is called again at specific intervals, and the image rendering parameters are calculated to re-render the image, or the rendering time information may be how often the image is re-rendered based on the obtained image rendering parameters, or the rendering time information may be the total time of displaying the rendered image by the terminal, or the rendering time information may be a time parameter related to a variable in the rendering parameter calculation function, and the rendering parameter calculation function needs to calculate the rendering parameter corresponding to the rendering time information according to the rendering time information, and so on.
For example, the technician may read the following code statement "uniform float iTime; "define time parameter, in the rendering parameter calculation function, may include the following code statement" float time ═ iTime ═ 25; "," from + ═ vec3(time 2, time-2.); "and the like, and establishes an association relationship between the rendering parameters and the rendering time information.
In an actual use process, an image with a target image effect may be rendered according to an operation behavior of a user on a terminal, that is, the image rendering method provided in the embodiment of the present invention may further include:
generating operation information in response to a trigger operation input by a user;
correspondingly, the step of invoking the rendering parameter calculation function and calculating the image rendering parameter corresponding to the target image effect based on the rendering information may include:
and calling a rendering parameter calculation function, and calculating the image rendering parameters corresponding to the target image effect according to the rendering information and the operation information.
The operation information may be a click, a slide, a long press, and the like of the user, for example, the click position of the user may be used as the rendering position of the image, or a new image rendering position may be determined according to the click position of the user and a preset image rendering position, and the like.
For another example, different frames of the moving image may be displayed according to the sliding operation of the user, for example, the moving image is a flickering star, and a star at different positions in the moving image may be displayed according to the sliding operation of the user.
204. And performing image rendering based on the image rendering parameters to obtain an image with a target image effect.
As shown in fig. 6, an image rendering module specially implementing an image rendering function may be disposed in the terminal, and the image rendering module may include a parsing module and a rendering module, where the parsing module may perform step 202 and step 203, and the rendering module may perform step 204.
In some alternative embodiments, step 204 may include:
determining an image rendering boundary with a target image effect based on the rendering position parameter and the rendering size parameter;
determining an image display range based on the image rendering boundary;
and performing image rendering in the image display range based on the rendering color parameters to obtain an image with a target image effect.
The image rendering boundary may be an image rendering boundary point, an image rendering boundary line, or the like. If the image rendering boundary is an image rendering boundary point, the step "determining an image display range based on the image rendering boundary" may include:
and connecting the image rendering boundary points, and determining the range determined by the connected image rendering boundary points as an image display range.
It can be understood that a skilled person may generate rendering code files corresponding to different image effects in advance according to the different image effects. Therefore, before the step "obtaining the rendering code file corresponding to the target image effect", the image rendering method provided in the embodiment of the present invention may further include:
acquiring a target image corresponding to a target image effect;
performing color analysis on display colors of the target image, and generating rendering color information based on a result of the color analysis;
acquiring preset rendering size information and rendering position information;
generating rendering information according to the rendering size information, the rendering position information and the rendering color information;
and generating a rendering code file according to the rendering information.
For example, the target image effect to be rendered may be a straight line, which may be represented by y ═ kx + b, and different colors of points on the line may all be represented by rendering color information. Meanwhile, the complicated picture mathematics field has a noise function and a fuzzy function to further process the target image effect.
As can be seen from the above, the embodiment of the present invention may obtain a rendering code file corresponding to a target image effect, analyze the rendering code file to obtain rendering information and a rendering parameter calculation function corresponding to the target image effect, call the rendering parameter calculation function, calculate an image rendering parameter corresponding to the target image effect based on the rendering information, perform image rendering based on the image rendering parameter, and obtain an image with the target image effect; according to the embodiment of the invention, the rendering information and the rendering parameter calculation function required by image rendering are stored in the rendering code file, when the image is required to be rendered, the image file is not required to be obtained for rendering, and only the rendering code file occupying less storage resources, transmission resources and the like is required to be obtained, so that the requirements on the storage resources, the transmission resources and the calculation resources can be reduced, the image rendering cost is saved, and the image rendering speed is increased.
The method according to the preceding embodiment is illustrated in further detail below by way of example.
In this embodiment, the system of fig. 1 will be explained.
As shown in fig. 3, a specific flow of the image rendering method of the present embodiment may be as follows:
301. and the terminal generates an image rendering request and sends the image rendering request to the server.
The image rendering request can be triggered by the operation of a user or generated by the terminal. For example, the image rendering request may be generated by operation triggering such as clicking and sliding by a user, or the image rendering request may be automatically generated by the terminal at set time intervals when a technician sets a certain target image effect to be displayed at fixed time, and so on.
The server may be a physical server disposed outside the terminal, a cloud server that can communicate with the terminal, or the server may be disposed inside the terminal, and so on. The invention is not limited in this regard.
302. And the server receives an image rendering request sent by the terminal and sends a rendering code file corresponding to the target image effect to the terminal according to the image rendering request.
Specifically, the image rendering request may include a target image effect identifier, and after receiving the image rendering request, the server may determine, based on a preset correspondence between the image effect identifier and the image effect, a target image effect corresponding to the target image effect identifier, and then determine a rendering code file corresponding to the target image effect.
303. And the terminal acquires a rendering code file corresponding to the target image effect.
It is understood that the rendering code file corresponding to the target image effect may be one file, or when determining the rendering code file, at least two corresponding code files may be determined according to the target image effect. For example, a first rendering code file corresponding to an image and a second rendering code file corresponding to other effects may be set.
For example, an image a corresponds to a first rendering code file a, a dynamic image B corresponds to a first rendering code file B, an image edge having a flicker effect corresponds to a second rendering code file 1, and an image having a timing display effect corresponds to a second rendering code file 2. When it is determined that the target image effect is the image a having a flicker effect at the edge of the image, the first rendering code file a and the second rendering code file 1 are acquired, and so on.
304. And the terminal analyzes the rendering code file to obtain a character string in a preset format.
The process of analyzing the rendering code file may be a process of performing operations such as file stream reading and storing on the obtained rendering code file by the terminal.
For example, the process of the terminal parsing the rendering code file may include: and reading the content in the rendering code File stored in the terminal disk after downloading through a byte input stream technology, such as a File inputstream technology in Java, to obtain a character string in a preset format, and storing the read character string in a memory of the terminal, and the like.
305. And analyzing the character string by the terminal to obtain rendering information, rendering time information and a rendering parameter calculation function corresponding to the target image effect.
The process of parsing the character string may be a process of dividing the character string according to a marker in the character string, for example, identification information or a keyword may be set for the rendering information, the rendering time information, and the rendering parameter calculation function, and when the character string is read, the read content may be determined to be the rendering information, the rendering time information, or the rendering parameter calculation function according to the read identification information and/or the keyword.
For example, in the actual use process, the codes of the functions may be calculated in advance for different rendering parameters, different program class names may be set according to different calculation functions, the functions may be calculated according to different class names and different rendering parameters at the parsing position when the character string is parsed, and the like.
306. And the terminal calls a rendering parameter calculation function and calculates the image rendering parameters corresponding to the target image effect based on the rendering information and the rendering time information.
For example, the target image effect may be rendering a pair of dynamic starry sky images, and then the dynamic starry sky images may be decomposed into different frames at different times for display. A rendering parameter calculation function may be invoked to determine the refresh time per frame of the dynamic image, as well as the specific image rendering parameters at each refresh.
307. And the terminal carries out image rendering based on the image rendering parameters to obtain an image with a target image effect.
Specifically, step 307 may include determining an image rendering boundary having the target image effect based on the rendering position parameter and the rendering size parameter;
determining an image display range based on the image rendering boundary;
and performing image rendering in the image display range based on the rendering color parameters to obtain an image with a target image effect.
In some embodiments, the terminal may display the image while rendering the image, and in other embodiments, the terminal may display the rendered image with the target image effect after all the images are rendered, which is not limited in the present invention.
Therefore, the embodiment of the invention can reduce the requirements on storage resources, transmission resources and computing resources, save the image rendering cost and improve the image rendering speed.
