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 application.
In the prior art, in the process of rendering an image of an electronic tag, the image is directly rendered into a vector diagram. However, there is a demand for adding more elements to the electronic label image, for example, adding new elements to the electronic label image so as to adapt to more application scenarios.

The following describes a rendering method of an electronic tag image according to an embodiment.
Referring to fig. 1, fig. 1 is a flowchart illustrating a rendering method of an electronic tag image according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, receiving image drawing data;
this step is intended to acquire image drawing data. The image drawing data is data for drawing an electronic label image. The image drawing data cannot be used for direct presentation or display.
Generally, the image drawing data is data indicating what content needs to be displayed in the electronic label image. For example, the image drawing data may include: the main title is 'multifunctional display', the auxiliary title is 'top-level IPS hard screen', the price data is '1999', and the two-dimension code information and the commodity bar code information are purchased. As can be seen, the image drawing data is the main content describing the information that needs to be displayed in the electronic label.
In this step, the image drawing data may be obtained in a wired manner, may be obtained in a network manner, or may be obtained in a wireless technique manner. It is to be understood that the manner of acquiring the image drawing data in this step is not exclusive, and is not limited herein.
Optionally, this step may include:
and acquiring the received image drawing data through a preset path.
It can be seen that the present alternative is primarily described with respect to how image drawing data is acquired. The optional solution summarization is mainly to acquire the image drawing data through a preset path. The predetermined path includes, but is not limited to, wired, wireless and network modes.
S102, analyzing the rendering mode of different elements in the image drawing data according to a preset element dictionary to obtain rendering operations corresponding to the different elements;
on the basis of S101, in this step, different elements in the image drawing data are subjected to rendering mode analysis according to a preset element dictionary, so as to obtain rendering operations corresponding to the different elements. That is, each element in the image drawing data is subjected to type judgment according to a preset element dictionary, and a rendering operation corresponding to the type is selected.
For example, if the element of the corresponding character type is parsed, the rendering operation of the character type is matched. Or the element of the corresponding picture type is analyzed, and then the rendering operation of the picture type is matched. Or the two-dimensional code type element is analyzed, the rendering operation of the two-dimensional code type can be matched, so that the corresponding two-dimensional code image is generated through the link information.
The preset element dictionary in this step is a data structure of a type corresponding to a key value containing element information, and the corresponding value and the corresponding type value can be obtained under the condition of a known key. In this step, the type of the element is analyzed, and the rendering operation corresponding to the type can be obtained through the preset element dictionary.
The preset element dictionary may be constructed and acquired by technicians according to different experiences, or may be constructed and acquired by image processing equipment according to executable rendering operations and types.
Optionally, this step may include:
step 1, checking elements of image drawing data according to a preset element dictionary to obtain an element type corresponding to each element;
and 2, matching corresponding rendering operation according to the element type corresponding to each element.
It can be seen that the present alternative is primarily illustrative of determining rendering operations. In the alternative scheme, firstly, elements of image drawing data are checked according to a preset element dictionary to obtain an element type corresponding to each element; and then, matching the corresponding rendering operation according to the element type corresponding to each element.
S103, performing corresponding rendering operation on each element according to the sequence of the image drawing data and the image data of each element to obtain an electronic tag image.
On the basis of S102, this step is intended to perform a corresponding rendering operation on each element according to the order in the image drawing data and the image data of each element, resulting in the electronic tag image.
The sequence of the image drawing data is used for determining the sequence of elements rendered in the image, and further when the covering condition among the elements occurs, a certain element is determined to be displayed, and the element is covered.
Specifically, when a rendering operation corresponding to an element is performed on the element, ID information, type information, X-axis information, Y-axis information, height information, width information, color information, and other information of the element are mainly acquired, and the rendering operation is performed according to the above information to render the element into an image. It is conceivable that different information should exist for different types of elements, so that a specific rendering operation is performed for different types of elements, and that rendering can be performed in different element types.
Optionally, this step may include:
step 1, acquiring image data corresponding to each element from image drawing data;
and 2, performing corresponding rendering operation on each element according to the image data corresponding to the element according to the sequence of the image drawing data to obtain the electronic tag image.
It can be seen that the alternative scheme mainly explains how to obtain the electronic tag image. Firstly, acquiring image data corresponding to each element from image drawing data; and then, performing corresponding rendering operation on each element according to the image data corresponding to the element according to the sequence of the image drawing data to obtain the electronic tag image.
Optionally, this embodiment may further include:
and when a new element is acquired, adding the image data of the element to the electronic tag image according to the rendering operation corresponding to the new element to acquire a new electronic tag image.
It can be seen that the present embodiment will be described when a new element is added to the electronic tag image. When a new element is acquired, the rendering operation corresponding to the element type is executed to obtain the image content of the element, and then the image content is added to the electronic tag image to obtain a new electronic tag image.
In summary, in the embodiment, the image drawing data is received, then the rendering modes of different elements in the image drawing data are analyzed according to the preset element dictionary, so that the rendering operations corresponding to the different elements are determined, and finally, each element is independently rendered according to the sequence of the image drawing data and the image data of each element, so as to obtain the electronic tag image, so that independent rendering operations can be performed on the elements of different types, and the richness of electronic tag rendering is improved.
The following further describes an apparatus for rendering an electronic tag image according to a specific embodiment.
In this embodiment, the method may include:
step 1, receiving image drawing data;
step 2, performing rendering mode analysis on different elements in the image drawing data according to a preset element dictionary to obtain rendering operations corresponding to the different elements;
and 3, performing corresponding rendering operation on each element according to the sequence of the image drawing data and the image data of each element to obtain the electronic tag image.
The image data of each element in the image drawing data of the present embodiment includes various image information for rendering.
For example, the following may be used:
"0":{
"id" is an "element id",
type element type "
......
}
Where "0" represents the level of the element, which is used to determine the rendering order of the element, starting from 0 to infinity, the smallest representing that it will be rendered first on the picture, the largest meaning that it will be rendered last.
Specifically, in the process of rendering each element, two data need to be determined, one is to determine the type of the element, and then the image data device calls the processing module of the corresponding type to perform rendering, and the other is how to render the element, and the processing module of the corresponding type obtains the required data from the element data and completes the subsequent rendering.
For example, when a two-dimensional code is rendered, the following data are obtained:
"9":{
"id":"qrcode",
"type":"grapcode_qr",
"x":270,
"y":180,
"width":80,
"height":80,
"color":"black",
"content":https://minew.com
},
from the above data, it is found that this will be the 10 th element rendered and its id is "qrcode", which is its "identification card" will not be repeated within the entire data. The types are: "grapcode _ qr" means that the element is a two-dimensional code type, x/y determines the coordinate position of the element on the image, width/height means that the width and height of the two-dimensional code are both 80, the color of the element is black, and the content is "https:// minwtech.com", meaning that the generated two-dimensional code contains the content of the website.
For distance, the text is rendered, and the following data are acquired:
"4":{
"id":"name",
"type":"text",
"x":10,
"y":240,
"align":"left",
"font_size":9,
"bold":false,
"font_family":"sourcehansans",
"color":"black"
content, ESL electronic label "
}
According to the data, the element is shown to be the 5 th element to be rendered, id is name, type text refers to that it is a text element, x/y is the coordinate position of the element in the image, align refers to the typesetting direction of the text, left alignment, right alignment and centering are supported currently, the font size is 9, thickening is not needed, the rendering font used is sourcehansans, the color is black, and the text content is an ESL electronic label.
Obviously, the rendering mode of each element can be determined according to the data information in the above example, and then, the rendering operation is performed on each element according to the data information through the corresponding rendering operation, so as to obtain the corresponding electronic tag image.
It can be seen that, in the embodiment, by receiving the image drawing data, then performing rendering mode analysis on different elements in the image drawing data according to the preset element dictionary, so as to determine rendering operations corresponding to the different elements, and finally performing the rendering operation on each element separately according to the sequence of the image drawing data and the image data of each element, an electronic tag image is obtained, so that independent rendering operations can be performed on the elements of different types, and richness in rendering of the electronic tag is improved.
